Program to Print Floyd’s Triangle in C, C++, and Python

Below are the ways to print Floyd’s triangle in C, C++, and Python.

• Using For loop(Static Input)
• Using For loop(User Input)

Method #1: Using For Loop (Static Input)

Approach:

• Give the number of rows of the triangle as static input and store it in a variable.
• Take a variable and initialize it with 1 say sampNum.
• Loop from 1 to the number of rows of the triangle using For loop.
• Using another For loop, loop from 1 to the parent loop iterator value (Nested For loop).
• Inside the inner for loop print the sampNum with a space character.
• Increase the value of sampNum by 1.
• Print the Newline Character after the end of the inner for loop.
• The Exit of the program.

1) Python Implementation

Below is the implementation:

# Give the number of rows of the triangle as static input and store it in a variable.
triRows = 10
# Take a variable and initialize it with 1 say sampNum.
sampNum = 1
# Loop from 1 to the number of rows of the triangle using For loop.
for m in range(1, triRows+1):
  # Using another For loop, loop from 1 to the parent loop iterator value (Nested For loop).
    for n in range(1, m+1):
        # Inside the inner for loop print the sampNum with a space character.
        print(sampNum, end=' ')
        # Increase the value of sampNum by 1.
        sampNum = sampNum+1
    # Print the Newline Character after the end of the inner for loop.

Program to Print Box Number Pattern in C, C++, and Python

Below are the ways to Print Box Number Pattern in C, C++, and python.

• Box Pattern with 1 and 0 characters (Outer Elements 1 and Inner elements 0)
• Box Pattern with 1 and 0 characters (Outer Elements 0 and Inner elements 1)

Method #1: Box Pattern with 1 and 0 characters (Outer Elements 1 and Inner elements 0)

Approach:

• Give the number of rows and number of columns of the box as static or user input and store them in two separate variables.
• Loop from 1 to the number of rows of the box +1 using a For loop.
• Loop from 1 to the number of columns of the box +1 using another Nested For loop.
• Check if the parent iterator value is equal to 1 or the number of rows of the box using the If statement.
• Check if the inner loop iterator value is equal to 1 or the number of columns of the box using the If statement.
• Merge these two conditions in a single If statement using or operator.
• If the condition is true then print 1 with a space character.
• Else print 0 with a space character.
• Print the newline character after the end of the inner For loop.
• The Exit of the Program.

1) Python Implementation

Below is the implementation:

# Give the number of rows and number of columns of the box as static or user input
# and store them in two separate variables.
boxrows = 11
boxcolumns = 19
# Loop from 1 to the number of rows of the box +1 using a For loop.
for m in range(1, boxrows+1):
    # Loop from 1 to the number of columns of the box +1 using another Nested For loop.
    for n in range(1, boxcolumns+1):
        '''Check if the parent iterator value is equal to 1 or the number of rows of the box using the If statement.
            Check if the inner loop iterator value is equal to 1 or the number of columns of the box using the If statement.
            Merge these two conditions in a single If statement using or operator.       
                  '''
        if(m == 1 or m == boxrows or n == 1 or n == boxcolumns):
            # If the condition is true then print 1 with a space character.
            print("1", end=" ")
        else:
            # Else print 0 with a space character.
            print("0", end=" ")
    # Print the newline character after the end of the inner For loop.
    print()

Program to Print Right Triangle Number Pattern in C, C++, and Python

Below are the ways to print the Right Triangle Number Pattern in C, C++, and Python.

• Using For Loop (Static Input)
• Using For Loop (User Input)

Method #1: Using For Loop (Static Input)

Approach:

• Give the number of rows of the right-angled triangle Number pattern as static input and store it in a variable.
• Loop from 1 to the number of rows using For loop.
• Loop from 1 to first loop iterator value using another Nested For loop.
• Print the iterator value of the parent loop with space in the inner For loop. (This prints the same number parent loop number of times)
• Print the newline character after ending of inner For loop.
• The Exit of the program.

1) Python Implementation

Below is the implementation:

# Give the number of rows of the right-angled triangle Number pattern
# as static input and store it in a variable.
triangleNum = 11
# Loop from 1 to the number of rows using For loop.
for m in range(1, triangleNum+1):
    # Loop from 1 to first loop iterator value using another Nested For loop.
    for n in range(1, m+1):
        # Print the iterator value of the nested loop with space in the inner For loop.
        # (This prints the same number parent loop number of times)
        print(m, end=' ')
    # Print the newline character after ending of inner For loop.
    print()

# Give the number of rows of the right-angled triangle star pattern
# as static input and store it in a variable.
trianglerows = 19
# Loop from 1 to the number of rows using For loop.
for m in range(1, trianglerows+1):
    # Loop from 1 to first loop iterator value using another Nested For loop.
    for n in range(1, m+1):
        # Print the star character with space in the inner For loop.
        print('*', end=' ')
    #Print the newline character after ending of inner For loop.

Program to Print Hollow Box Number Pattern in C, C++, and Python

Below are the ways to Print Hollow Box Number Pattern in C, C++, and python.

• Using For Loop (Static Character)
• Using For Loop (User Character)

Method #1: Using For Loop (Static Character)

Approach:

• Give the number of rows and number of columns of the box as static or user input and store them in two separate variables.
• Loop from 1 to the number of rows of the box +1 using a For loop.
• Loop from 1 to the number of columns of the box +1 using another Nested For loop.
• Check if the parent iterator value is equal to 1 or the number of rows of the box using the If statement.
• Check if the inner loop iterator value is equal to 1 or the number of columns of the box using the If statement.
• Merge these two conditions in a single If statement using or operator.
• If the condition is true then print 1 with a space character.
• Else print space character.
• Print the newline character after the end of the inner For loop.
• The Exit of the Program.

Method #2: Using For Loop (User Character)

Approach:

• Give the number of rows and number of columns of the box as user input and store them in two separate variables.
• Give the character to print as a box pattern as user input and store it in a variable.
• Loop from 1 to the number of rows of the box +1 using a For loop.
• Loop from 1 to the number of columns of the box +1 using another Nested For loop.
• Check if the parent iterator value is equal to 1 or the number of rows of the box using the If statement.
• Check if the inner loop iterator value is equal to 1 or the number of columns of the box using the If statement.
• Merge these two conditions in a single If statement using or operator.
• If the condition is true then print the given character with a space character.
• Else print space character.
• Print the newline character after the end of the inner For loop.
• The Exit of the Program.

1) Python Implementation

• Give the number of rows of the box as user input using int(input()) and store it in a variable.
• Give the number of columns of the box as user input using int(input()) and store it in another variable.
• Give the Character as user input using input() and store it in another variable.

Below is the implementation:

# Give the number of rows and number of columns of the box as user input and store them in two separate variables.
boxrows = int(input("Enter some random number of rows of the box = "))
boxcolumns = int(input("Enter some random number of columns of the box = "))
# Give the character to print as a box pattern as user input and store it in a variable.
userchar = input('Enter some random character to print = ')
# Loop from 1 to the number of rows of the box +1 using a For loop.
for m in range(1, boxrows+1):
    # Loop from 1 to the number of columns of the box +1 using another Nested For loop.
    for n in range(1, boxcolumns+1):
        '''Check if the parent iterator value is equal to 1 or the number of rows of the box using the If statement.
            Check if the inner loop iterator value is equal to 1 or the number of columns of the box using the If statement.
            Merge these two conditions in a single If statement using or operator.       
                  '''
        if(m == 1 or m == boxrows or n == 1 or n == boxcolumns):
            # If the condition is true then print the given character with a space character.
            print(userchar, end=" ")
        else:
            # Else print space character.
            print(" ", end=" ")
    # Print the newline character after the end of the inner For loop.
    print()

Output:

Enter some random number of rows of the box = 9
Enter some random number of columns of the box = 13
Enter some random character to print = &

2) C++ Implementation

• Give the number of rows of the box as user input using cin and store it in a variable.
• Give the number of columns of the box as user input using cin and store it in another variable.
• Give the Character as user input using cin and store it in another variable.

Below is the implementation:

#include <iostream>
using namespace std;

int main()
{
    // Give the number of rows of the box as user input
    // using cin and store it in a variable.
    // Give the number of columns of the box as user input
    // using cin and store it in another variable.
    int boxrows;
    int boxcolumns;
    cin >> boxrows;
    cin >> boxcolumns;
    // Give the Character as user input using cin and store
    // it in another variable.
    char userchar;
    cin >> userchar;
    cout << endl;
    // Loop from 1 to the number of rows of the box +1 using
    // a For loop.
    for (int m = 1; m <= boxrows; m++) {
        // Loop from 1 to the number of columns of the box
        // +1 using another Nested For loop.
        for (int n = 1; n <= boxcolumns; n++) {
            /*Check if the parent iterator value is equal to
               1 or the number of rows of the box using the
               If statement. Check if the inner loop
               iterator value is equal to 1 or the number of
               columns of the box using the If statement.
                Merge these two conditions in a single If
               statement using or operator. */
            if (m == 1 || m == boxrows || n == 1
                || n == boxcolumns) {
                // If the condition is true then print user
                // character with a space character.
                cout << userchar << " ";
            }
            else {
                // Else print space character.
                cout << "  ";
            }
        }
        // Print the newline character after the end of the
        // inner For loop.
        cout << endl;
    }

    return 0;
}

Enter some random number of rows of the box = 9
Enter some random number of columns of the box = 13
Enter some random character to print = &

    // it in another variable.
    char userchar;
    scanf("%d%d%c",&boxrows,&boxcolumns,&userchar);
    printf("\n");
    // Loop from 1 to the number of rows of the box +1 using
    // a For loop.
    for (int m = 1; m <= boxrows; m++) {

               iterator value is equal to 1 or the number of
               columns of the box using the If statement.
                Merge these two conditions in a single If
               statement using or operator. */
            if (m == 1 || m == boxrows || n == 1
                || n == boxcolumns) {
                // If the condition is true then print user
                // character with a space character.
                printf("%c ", userchar);
            }
            else {
                // Else print space character.
                printf("  ");
            }
