Program to Print Pyramid Star Pattern in C, C++, and Python
Below are the ways to print Pyramid Star Pattern in C, C++, and Python.
Method #1: Using For Loop (Star Character)
Approach:
- Give the number of rows of the pyramid as static input and store it in a variable.
- Loop from 0 to the number of rows using For Loop.
- Loop from 0 to the number of rows – iterator value-1 of the parent For loop using another Nested For loop(Inner For loop).
- Print the space character in the inner For loop.
- Loop from 0 to the iterator value+1 of the parent For loop using another Nested For loop(Inner For loop).
- Print the star character with a space character in the inner For loop.
- After the end of the two inner For loops print the newline character.
- The Exit of the Program.
1) Python Implementation
Below is the implementation:
# Give the number of rows of the pyramid as static input and store it in a variable.
pyRows = 10
# Loop from the number of rows to 0 in decreasing order using For Loop.
# Loop from 0 to the number of rows using For Loop.
for m in range(0, pyRows):
# Loop from 0 to the number of rows - iterator value-1 of the parent For loop\
# using another Nested For loop(Inner For loop).
for n in range(0, pyRows-m-1):
# Print the space character in the inner For loop.
print(end=' ')
# Loop from 0 to the iterator value+1 of the parent For loop
# using another Nested For loop(Inner For loop).
for l in range(0, m+1):
# Print the star character with a star character in the inner For loop.
print('*', end=' ')
print()
Output:
*
* *
* * *
* * * *
* * * * *
* * * * * *
* * * * * * *
* * * * * * * *
* * * * * * * * *
* * * * * * * * * *
2) C++ Implementation
Below is the implementation:
#include <iostream>
using namespace std;
int main()
{
// Give the number of rows of the pyramid as static
// input and store it in a variable.
int pyRows = 10;
// Loop from 0 to the number of rows using For Loop.
for (int m = 0; m < pyRows; m++) {
// Loop from 0 to the number of rows - iterator value-1 of the parent For loop\
// using another Nested For loop(Inner For loop).
for (int n = 0; n < pyRows - m - 1; n++) {
// Print the space character in the inner For
// loop.
cout << " ";
}
// Loop from 0 to the iterator value+1 of the parent
// For loop
// using another Nested For loop(Inner For loop).
for (int l = 0; l < m + 1; l++) {
// Print the star character with a space
// character in the inner For loop.
cout << "* ";
}
// Print the Newline Character after the end of the
// inner for loop.
cout << endl;
}
return 0;
}
Output:
*
* *
* * *
* * * *
* * * * *
* * * * * *
* * * * * * *
* * * * * * * *
* * * * * * * * *
* * * * * * * * * *
3) C Implementation
Below is the implementation:
#include <stdio.h>
int main()
{
// Give the number of rows of the pyramid as static
// input and store it in a variable.
int pyRows = 10;
// Loop from 0 to the number of rows using For Loop.
for (int m = 0; m < pyRows; m++) {
// Loop from 0 to the number of rows - iterator value-1 of the parent For loop\
// using another Nested For loop(Inner For loop).
for (int n = 0; n < pyRows - m - 1; n++) {
// Print the space character in the inner For
// loop.
printf(" ");
}
// Loop from 0 to the iterator value+1 of the parent
// For loop
// using another Nested For loop(Inner For loop).
for (int l = 0; l < m + 1; l++) {
// Print the star character with a space
// character in the inner For loop.
printf("* ");
}
// Print the Newline Character after the end of the
// inner for loop.
printf("\n");
}
return 0;
}

Method #2: Using For Loop (User Character)
Approach:
- Give the number of rows of the pyramid as user input and store it in a variable.
- Give the character as static input and store it in a variable.
- Loop from the number of rows to 0 in decreasing order using For Loop.
- Loop from 0 to the number of rows – iterator value of the parent For loop using another Nested For loop(Inner For loop).
- Print the space character in the inner For loop.
- Loop from 0 to the iterator value of the parent For loop using another Nested For loop(Inner For loop).
- Print the given character with a space character in the inner For loop.
- After the end of the two inner For loops print the newline character.
- The Exit of the Program.
1) Python Implementation
- Give the number of rows of the pyramid 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:
# Give the number of rows of the pyramid as user input using int(input()) and store it in a variable.
pyRows = int(input(
'Enter some random number of rows of pyramid = '))
# Give the Character as user input using input() and store it in another variable.
givencharacter = input('Enter some random character = ')
# Loop from 0 to the number of rows using For Loop.
for m in range(0, pyRows):
# Loop from 0 to the number of rows - iterator value-1 of the parent For loop\
# using another Nested For loop(Inner For loop).
for n in range(0, pyRows-m-1):
# Print the space character in the inner For loop.
print(end=' ')
# Loop from 0 to the iterator value+1 of the parent For loop
# using another Nested For loop(Inner For loop).
for l in range(0, m+1):
# Print the given character with a space character in the inner For loop.
print(givencharacter, end=' ')
print()
Output:
Enter some random number of rows of pyramid = 10
Enter some random character = ^

2) C++ Implementation
- Give the number of rows of the pyramid as user input using scanf and store it in a 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
// as user input using cin and store it in a
// variable.
int pyRows;
char givencharacter;
cout << "Enter some random number of rows = " << endl;
cin >> pyRows;
// Give the Character as user input using cin and store
// it in another variable.
cout << "Enter some random character = " << endl;
cin >> givencharacter;
cout << endl;
// Loop from 0 to the number of rows using For Loop.
for (int m = 0; m < pyRows; m++) {
// Loop from 0 to the number of rows - iterator value-1 of the parent For loop\
// using another Nested For loop(Inner For loop).
for (int n = 0; n < pyRows - m - 1; n++) {
// Print the space character in the inner For
// loop.
cout << " ";
}
// Loop from 0 to the iterator value+1 of the parent
// For loop
// using another Nested For loop(Inner For loop).
for (int l = 0; l < m + 1; l++) {
// Print the given character with a space
// character in the inner For loop.
cout <<givencharacter<<" ";
}
// Print the Newline Character after the end of the
// inner for loop.
cout << endl;
}
return 0;
}

Enter some random number of rows of pyramid =
10
Enter some random character =
