C Program To Print Triangle

A triangle pattern in C is a pattern of characters arranged in successive rows to form a triangular shape. It can be printed using nested loops, where the outer loop controls the rows and the inner loop prints the characters.

• The number of characters increases with each row.
• Nested loops are used to control the rows and characters in the pattern.

Example

Input:  5

Output:

* 
* * 
* * * 
* * * * 
* * * * *

Approach

The triangle pattern can be printed using two nested loops:

• Take the number of rows n as input.
• Use the outer loop to iterate through each row.
• Use the inner loop to print stars in the current row.
• Print a newline after each row.

#include <stdio.h>

int main() {
    int n;

    scanf("%d", &n);

    // Iterate through each row
    for (int i = 1; i <= n; i++) {

        // Print stars in the current row
        for (int j = 1; j <= i; j++) {
            printf("* ");
        }

        printf("\n");
    }

    return 0;
}  

Output

For input 5, the output is:

*
* *
* * *
* * * *
* * * * *

Explanation

• The outer loop runs from 1 to n and represents the rows.
• The inner loop runs from 1 to i, so each row contains i stars.
• printf("\n") moves the cursor to the next line after printing each row.
