So, I have to print this pattern but my code dont work.

And my code is printing this:

My code:


#include <stdio.h>

int stars(int n) {
    
    if(n==1){
       printf("*");
       return;
     }
    // i = 0 ; i<3; i++//
    // 2*3-1 = 5
    for(int i=0; i<n; i++){
    
    for(int z=0; z<((2*n)-1) ; z++){
     
    printf("*");
    
    }
    
    printf("\n");
    
    }
    
}

int main() {

    stars(3);

    return 0;
}

Your problem is that in the second loop you always iterate for 2*n-1 you should iterate based on the iteration variable i

for(int z=0; z<((2*i)+1) ; z++)

The first loop that you wrote iterate on the number of lines, for each line you want a different amount of printf(“*”) but if the number of iterations is constant (because n Doesn’t change) the amount of printing will also be constant. This is the reason you printed the same amount of “*” for each line.
