In this program, we will learn, how we can print reverse full pyramid using ‘asterisks’ and ‘loops’.

C program

#include <stdio.h>

int main()
{
    int a, b, rows, space;

    printf("Enter number of rows: ");
    scanf("%d", &rows);
    for (a = 5; a >= 1; a--) //decease number of rows
    {
        //print magin space
        for (b = 1; b <= space; b++)
            printf(" ");

        //this loop prints half part of pyramid
        for (b = 1; b <= a; b++)
            printf("*");

        //this loop prints remaining half part of pyramid
        for (b = a - 1; b >= 1; b--)
            printf("*");

        printf("\n");
        space++;
    }

    return 0;
}

Output:

Enter number of rows: 5
