Hi everyone, im new to C and I'm stuck doing an exercise that asks me to draw an empty square of " * " using "while" and where n = side (side must be >=1 and <= 20) I succeeded to make a square of asterisks like this:

now i need to do the same thing but the box needs to be empty:Code:n = 6 ****** ****** ****** ****** ****** ******

This is the code i wrote for the first exercise:Code:n = 6 ****** * * * * * * * * ******

Any help would be appreciate, I know this should be easy to do but im still a beginner..Code:#include <stdio.h> int main() { int n, i, j; printf("Insert a number between 1 and 20:\n"); scanf("%d", &n); if ((n >= 1)&&(n <=20)) { i = 0; while( i<n ) { i++; j = 0; while( j<n ) { printf("* ") ; j++; } printf("\n"); } } else printf("the square's side must be between 1 and 20.\n"); return 0; }
