Write a C Program to Print Diamond Star Pattern using for loop. This c Diamond Star Pattern example uses two sets of for loops to print the upper and lower portion of a diamond. There are nested for loops to iterate rows and columns and print the diamond star pattern.
#include<stdio.h> int main() { int i, j, rows; printf("Enter Diamond Rows = "); scanf("%d", &rows); printf("Diamond Star Pattern\n"); for(i = 1; i <= rows; i++) { for(j = 1; j <= rows - i; j++) { printf(" "); } for(j = 1; j <= i * 2 - 1; j++) { printf("*"); } printf("\n"); } for(i = rows - 1; i > 0; i--) { for(j = 1; j <= rows - i; j++) { printf(" "); } for(j = 1; j <= i * 2 - 1; j++) { printf("*"); } printf("\n"); } return 0; }

In this C Program, we removed the multiple for loops and used if statements to print Diamond Star Pattern.
#include<stdio.h> int main() { int i, j, k, rows; printf("Enter Diamond Rows = "); scanf("%d", &rows); int x = rows - 1; int y = 1; printf("Diamond Star Pattern\n"); for(i = 1; i <= rows; i++) { for(j = 1; j <= x; j++) { printf(" "); } for(k = 1; k <= y; k++) { printf("*"); } if(x > i) { x = x - 1; y += 2; } if(x < i) { x += 1; y = y - 2; } printf("\n"); } return 0; }
Enter Diamond Rows = 12

This C program allows entering a symbol and prints that symbol in a Diamond pattern using a while loop.
#include<stdio.h> int main() { int i, j, rows; printf("Enter Diamond Rows = "); scanf("%d", &rows); printf("Diamond Star Pattern\n"); i = 1; while(i <= rows) { j = 1; while(j <= rows - i) { printf(" "); j++; } j = 1; while(j <= i * 2 - 1) { printf("*"); j++; } printf("\n"); i++; } i = rows - 1; while(i > 0) { j = 1; while(j <= rows - i) { printf(" "); j++; } j = 1; while(j <= i * 2 - 1) { printf("*"); j++; } printf("\n"); i--; } return 0; }
Enter Diamond Rows = 11
