Program to Print the Pyramid of Horizontal Number Tables in C, C++, and Python

Below are the ways to Print the Pyramid of Horizontal Number Tables in C, C++, and Python.

Method #1: Using For loop (Static Input)

Approach:

• Give the number of rows as static 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 1 to parent loop iterator value using another For loop(Nested For Loop).
• Print the value of the product of parent loop iterator value and inner loop iterator value with space.
• After the end of the inner For loop print the Newline Character.
• 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.
numberows = 9
# Loop from 1 to the number of rows using For loop.
for m in range(1, numberows+1):
# Loop from 1 to the number of 1 to parent loop iterator value
# using another For loop(Nested For Loop).
for n in range(1, m+1):
# Print the value of the product of parent loop iterator value
# and inner loop iterator value with space.
print(m*n, end=" ")
# Print the newline character after the end of the inner For loop.
print()


Output:

1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49
8 16 24 32 40 48 56 64
9 18 27 36 45 54 63 72 81

2) C++ Implementation

Below is the implementation:

#include <iostream>
using namespace std;

int main()
{
// Give the number of rows as static input and store it
// in a variable.
int numberows = 9;

// Loop from 1 to the number of rows using For loop.
for (int m = 1; m <= numberows; m++) {
// Loop from 1 to the number of 1 to parent loop
// iterator value
// using another For loop(Nested For Loop).
for (int n = 1; n <= m; n++) {
// Print the value of the product of parent loop
// iterator value and inner loop iterator value
// with space.
cout << m * n << " ";
}
// Print the newline character after the end of
// the inner For loop.
cout << endl;
}

return 0;
}

Output:

1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49
8 16 24 32 40 48 56 64
9 18 27 36 45 54 63 72 81

3) C Implementation

Below is the implementation:

#include <stdio.h>
#include <string.h>
int main()
{

// Give the number of rows as static input and store it
// in a variable.
int numberows = 9;

// Loop from 1 to the number of rows using For loop.
for (int m = 1; m <= numberows; m++) {
// Loop from 1 to the number of 1 to parent loop
// iterator value
// using another For loop(Nested For Loop).
for (int n = 1; n <= m; n++) {
// Print the value of the product of parent loop
// iterator value and inner loop iterator value
// with space.
printf("%d ", m * n);
}
// Print the newline character after the end of
// the inner For loop.
printf("\n");
}
return 0;
}

9 18 27 36 45 54 63 72 81

Method #2: Using For loop (User Input)

Approach:

• Give the number of rows 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 1 to parent loop iterator value using another For loop(Nested For Loop).
• Print the value of the product of the parent loop iterator value and inner loop iterator value with space.
• After the end of the inner For loop 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 word as user input using int(input()) and store it in a variable.
numberows = int(input('Enter some random number of rows = '))
# Loop from 1 to the number of rows using For loop.
for m in range(1, numberows+1):
# Loop from 1 to the number of 1 to parent loop iterator value
# using another For loop(Nested For Loop).
for n in range(1, m+1):
# Print the value of the product of parent loop iterator value
# and inner loop iterator value with space.
print(m*n, end=" ")
# Print the newline character after the end of the inner For loop.
print()


Output:

Enter some random number of rows = 13

Below is the implementation:

#include <iostream>
using namespace std;

int main()
{
// Give the number of rows as user input using cin and
// store it in a variable.
int numberows;
cin >> numberows;

// Loop from 1 to the number of rows using For loop.
for (int m = 1; m <= numberows; m++) {
// Loop from 1 to the number of 1 to parent loop
// iterator value
// using another For loop(Nested For Loop).
