Program to Print the Equilateral triangle Pattern of Star in C, C++, and Python

Below are the ways to Print the Equilateral triangle Pattern of Star in C, C++, and Python.

• Using For loop(Star Character)
• Using For loop(User Character)

Method #1: Using For Loop (Star Character)

Approach:

• Give the number of rows as static input and store it in a variable.
• Take a variable to say g and initialize its value with (2*number of rows)-2.
• Loop from 0 to the number of rows using For loop.
• Loop from 0 to g using another For Loop(Inner For loop).
• Print the space character in the inner For Loop.
• Decrement the value of g by 1 after the end of the inner For loop.
• Loop from 0 to m+1 using another For loop(Nested For loop) where m is the iterator value of the parent For loop.
• Print the star character with space.
• Print the Newline character after the end of the Two inner For loops.
• The Exit of the Program.

1) Python Implementation

Below is the implementation:

# Give the number of rows as static input and store it in a variable.
numberOfRows = 8
# Take a variable to say g and initialize its value with (2*number of rows)-2.
g = (2*numberOfRows)-2
# Loop from 0 to the number of rows using For loop.
for m in range(0, numberOfRows):
    # Loop from 0 to g using another For Loop(Inner For loop).
    for n in range(0, g):
      # Print the space character in the inner For Loop.
        print(end=" ")
    # Decrement the value of g by 1 after the end of the inner For loop.
    g = g-1
    # Loop from 0 to m+1 using another For loop(Nested For loop)
    # where m is the iterator value of the parent For loop.
    for n in range(0, m+1):
      # Print the star character with space.
        print('*', end=" ")
    # Print the Newline character after the end of the Two inner For loops.

Program to Print Hollow Square Star Pattern in C, C++, and Python

Below are the ways to print the hollow square star pattern in C, C++, and Python.

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

Method #1: Using For loop (Star Character)

Approach:

• Give the side of the square as static input and store it in a variable.
• Loop till the side length of the square using For loop.
• Loop till the side length of the square using another nested For loop.
• We use the If Else statement to check If the side length is 0 or maximum – 1.
• If it is true then print * else print space.
• The Exit of the Program.

1) Python Implementation

Below is the implementation:

# Give the side of the square as static input and store it in a variable.
squareside = 6
# Loop till the side length of the square using For loop.
for m in range(squareside):
    # Loop till the side length of the square using another nested For loop.
    for n in range(squareside):
        # We use the If Else statement to check If the length or breadth number is 0 or maximum – 1.
        # If it is true then print * else print space.
        if(m == 0 or m == squareside - 1 or n == 0 or n == squareside - 1):
            print('*', end=' ')
        else:
            print(' ', end=' ')
    print()

Method #2: Using While Loop (User Input)

Approach:

• Give the number of rows as user input and store it in a variable.
• Take a variable(say f ) and initialize it 1.
• Loop till f is less than or equal to the number of rows using While Loop.
• Take a variable(say g ) and initialize it 1.
• Loop till g is is less than or equal to f i.e g<=f using Another While Loop(Nested While Loop).
• Inside the inner While Loop print the value of 2*f-1 with space.
• Increment the value of j by 1.
• After the end of the inner while loop increment the value of variable f by 1.
• Print the Newline character.
• The Exit of the Program.

1) Python Implementation

Give the number of rows as user input using int(input()) and store it in a variable.

Below is the implementation:

# Give the number of rows as user input using int(input()) and store it in a variable.
numberrows = int(input('Enter some random number of rows = '))
# Take a variable(say f ) and initialize it 1.
f = 1
# Loop till f is less than or equal to the number of rows using While Loop.
while(f <= numberrows):
    # Take a variable(say g ) and initialize it 1.
    g = 1
    # Loop till g is is less than or equal to f
    # i.e g<=f using Another While Loop(Nested While Loop).
    while g <= f:
        # Inside the inner While Loop print the value of 2*f-1 with space.
        print((f * 2 - 1), end=" ")
        # Increment the value of g by 1.
        g = g + 1
    # After the end of the inner while loop increment the value of variable f by 1.
    f = f + 1
    # Print the Newline character.

• Give the character to print as user input and store it in a variable.
• Loop from 1 to the number of rows using For Loop.
• Loop from 1 to the number of rows -iterator value of the parent For loop using another For loop(Nested For loop).
• Print the space character in the inner For loop.
• Loop from 0 to the 2* iterator value – 1 of the parent For loop using another For loop(Nested For loop).
• Print the given character.

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

Below is the implementation:

diamondrows = int(input(
    'Enter some random number of rows  = '))
# Give the Character as user input using input() and store it in another variable.
givencharacter = input('Enter some random character = ')
# Loop from 1 to the number of rows using For Loop.
for m in range(1, diamondrows+1):
    # Loop from 1 to the number of rows -iterator value of the parent
    # For loop using another For loop(Nested For loop).
    for n in range(1, diamondrows - m + 1):
        # Print the space character in the inner For loop.
        print(end=' ')
    # Loop from 0 to the 2* iterator value - 1 of the parent For loop
    # using another For loop(Nested For loop).
    for l in range(0, (2 * m) - 1):
        # Print the given character
        print(givencharacter, end='')
    # After the end of the inner for Loops print the Newline Character.
    print()

# Loop from 1 to the number of rows using For loop.
for m in range(1, diamondrows):
    # Loop from 1 to iterator value of the parent For loop
    # using another For loop(Nested For loop).
    for n in range(1, m+1):
        # Print the space character in the inner For loop.
        print(end=' ')

• Loop till the first iterator value using another For loop(Nested For loop).
• Check if the first loop iterator value is equal to the second loop iterator value using the If Statement.
• Check if the second loop iterator value is equal to 0 using the If Statement.
• Combine these two conditions using or operator.
• If the statement is true then print star character with space.
• Else print space character.
• After the end of the inner for loop print the Newline Character.
• After the end of two For loops Loop from 1 to the number of rows using For loop.
• Loop from the first iterator value to the given number of rows using another For loop(Nested For loop).
• Check if the first loop iterator value is equal to the second loop iterator value using the If Statement.

Method #2: Using For loop (User Character)

Approach:

• Give the number of rows of the number of diamond pattern as user input and store it in a variable.
• Give the character to print as user input and store it in a variable.
• Loop from 0 to the number of rows using For loop.
• Loop till the first iterator value using another For loop(Nested For loop).
• Check if the first loop iterator value is equal to the second loop iterator value using the If Statement.
• Check if the second loop iterator value is equal to 0 using the If Statement.
• Combine these two conditions using or operator.
• If the statement is true then print the given character with space.
• Else print space character.
• After the end of the inner for loop print the Newline Character.
• After the end of two For loops Loop from 1 to the number of rows using For loop.
• Loop from the first iterator value to the given number of rows using another For loop(Nested For loop).
• Check if the first loop iterator value is equal to the second loop iterator value using the If Statement.
• Check if the second loop iterator value is equal to the number of rows using the If Statement.
• Combine these two conditions using or operator.
• If the statement is true then print the given character with space.
• Else print space character.
• After the end of the inner for loop print the Newline Character.
• The Exit of the Program.
