C program to print a pyramid pattern

#include <stdio.h>

int main(void) {
    int rows = 4;

    for (int i = 1; i <= rows; i++) {
        for (int s = 1; s <= rows - i; s++) {
            printf(" ");
        }
        for (int j = 1; j <= 2 * i - 1; j++) {
            printf("*");
        }
        printf("\n");
    }
    return 0;
}

Output:

How it works

• The first inner loop prints the spaces on the left, so the pyramid is in the centre.
• The second inner loop prints the stars: 1, 3, 5, 7 in the four rows.
