53 : C Program to display star/asterisk triangle sequence 1

This is the most favorite program of teachers and you may usually see in these kind of programming papers and praticals.

You need to display the below triagle of stars/asterisks (like a right angle triangle of stars). There are 10 rows and each row has one asterisk less then the above starting from 1 asterisk.

To achive this you need to have 2 nested for loops.

Variables :

i : Datatype int : Used in for loop condition.

sum : Datatype int : To hold the sum of 1st 10 natural numbers. Should be initialized to zero



Logic :

The outer i for loop controls the row, and the inner j for loop prints the stars. Note that the loop breaks when j = i

 for(i = 0; i <= 10 ; i++) {
        
        for(j = 0; j <= i; j++) {
            
            printf("* ");
        }
        
        printf("\n");
        
    }
