Implementation:

#include <stdio.h> int main(void) { int n; int i,j; printf("Enter the size of the diamond:\n"); scanf("%d",&n); /* Upper hollow creation */ for(i=1;i<=n;i++) { for(j=n;j>=i;j--) { printf(" "); } printf("*"); for(j=n-i;j<n-1;j++) { printf(" "); } for(j=n-i;j<n-1;j++) { printf(" "); } printf("*"); printf("\n"); } /* lower hollow */ /* Whatever you typed for upper hollow, just copy and paste it below to create lower hollow. the only difference you have to make is in the outer for loop */ for(i=n;i>=1;i--) // see the difference here. started from n, till >=1 & decrements { for(j=n;j>=i;j--) { printf(" "); } printf("*"); for(j=n-i;j<n-1;j++) { printf(" "); } for(j=n-i;j<n-1;j++) { printf(" "); } printf("*"); printf("\n"); } return 0; }
