Simple C Program for Print Left Triangle Pattern

/*## Simple C Program for Print Left Triangle Pattern Example C Program */
/*## Basic Pattern Programs,Left Triangle Pattern C Programming*/

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

	// Declare Variables
    int rows,i,j;
    
    //Read Day Value
    printf("Enter the number of rows : ");
    scanf("%d",&rows);
     
    //Print Left Triangle Pattern
    for (i = 1; i <= rows; i++){
            for (j = 1; j <= i; j++){
                printf("*");
            }
      printf("\n");
     }
   
	return 0;
}

Sample Output:

Enter the number of rows : 7

How It Works

This C program demonstrates Left Triangle. It first reads the required values as input, then walks through the data with a loop to compute the result, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Read the input values that the program will work with.
3. Iterate over the data using a loop to apply the logic.
4. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
