Algorithm to print square star pattern using loop
- Take the number of stars in each side of square as input from user using scanf function. Let it be N.
- We will use two for loops to print square star pattern.
- In one iteration, outer for loop will print one row of pattern.
- In one iteration, inner for loop will print one star (*) characters in a row.
Here is the matrix representation of the square star pattern. The row numbers are represented by i whereas column numbers are represented by j.
C program to print square star pattern
#include<stdio.h>
int main(){
int side, i, j;
printf("Enter side of square\n");
scanf("%d", &side);
/* Row iterator for loop */
for(i = 0; i < side; i++){
/* Column iterator for loop */
for(j = 0; j < side; j++){
printf("*");
}
printf("\n");
}
return 0;
}
Output
Enter side of square 5 ***** ***** ***** ***** *****
