C Program – Print Simple Pyramid Pattern - Star Pyramid

Print Simple Pyramid Pattern

A pyramid pattern displays rows of stars centred with respect to the base. Each row contains one more star than the previous, creating a triangular shape. To print the pyramid, we use two inner loops: one for spaces and one for stars.

#include <stdio.h>
int main() {
    int rows;
    printf("Enter number of rows: ");
    scanf("%d", &rows);
    for (int i = 1; i <= rows; i++) {
        // Print spaces before stars
        for (int j = 1; j <= rows - i; j++) {
            printf(" ");
        }
        // Print stars for the current row
        for (int k = 1; k <= 2 * i - 1; k++) {
            printf("*");
        }
        printf("\n");             // Move to the next line after each row
    }
    return 0;
}

Enter number of rows: 4

Practice: Simple Pyramid

The nested loops manage the spacing and star counts for each row. Before printing stars, the program prints rows - i spaces so that the stars are centered. Then it prints 2*i - 1 stars, which increases by two for each row, giving the pyramid its shape.
