C Program to Print Right Triangle Star Pattern

In this tutorial, you will learn how to write a C program to print the right triangle star pattern.

This is how a right triangle pattern looks like:

Number of rows = 6
Output: 
* 
* * 
* * * 
* * * * 
* * * * *

Program to Print Right Triangle Star Pattern

#include <stdio.h>
int main() {
  int row, column, numberOfRows=8;
  for(row=0; row<numberOfRows; row++)
  {
    for(column=0; column<=row; column++)
    {
      printf("* ");
    }
    //This is just to print the stars in new line after each row
    printf("\n");
  }
  return 0;
}

Output:

Explanation of the program:

In this program, we are running a nested for loop. The outer for loop runs from 0 till numberOfRows, this basically prints the rows of the pattern. In this example the value of numberOfRows is 8 so the outer loop runs 8 times to print 8 rows of the right triangle star pattern.
The inner loop is responsible for printing the stars in the each row. It prints one star in the first row, two stars in the second row and so on.
After the inner loop ends there is a print statement for new line. This is to move the cursor to new line for the next row.
