C program to Print Diamond Pattern of Numbers

In this program, we will make a C program to print diamond patterns of numbers & a C program to print diamond patterns of stars using nested for loop and if-else statements.

C program to print diamond pattern of number

#include<stdio.h>
int main(){

    int n;
    printf("Enter Number:");
    scanf("%d",&n);
    
    int i=1;
    
    while(i<=n)
    {
        for(int j=1;j<=n-i;j++)
            printf(" ");
        
        for(int j=1;j<=i;j++)
            printf("%d", j);
        
        for(int j=i-1;j>0;j--)
            printf("%d", j);
        printf("\n");
        i++;
    }
    i=n-1;
    while(i>0)
    {
        for(int j=1;j<=n-i;j++)
        printf(" ");
        
        for(int j=1;j<=i;j++)
            printf("%d", j);
        
        for(int j=i-1;j>0;j--)
            printf("%d", j);
        printf("\n");
        i--;
    }
  
}

#include <stdio.h>
int main()
{
    int i, j, p;
    for (i = 1; i <= 5; i++)
    {
        p = 1;
        for (j = 1; j <= 9; j++)
        {
            if ((j <= 5 - i) || (j >= 5 + i))
            {
                printf(" ");
            }
            else
            {
                printf("%d", p);
                p++;
            }
        }
        printf("\n");
    }
    for (i = 1; i <= 4; i++)
    {
        p = 1;
        for (j = 1; j <= 9; j++)
        {
            if ((j <= i) || (j >= 10 - i))
            {
                printf(" ");
            }
            else
            {
                printf("%d", p);
                p++;
            }
        }
        printf("\n");
    }
    return 0;
}

Output:

C program to print diamond pattern of star

#include <stdio.h>
int main()
{
    int i, j;
    for (i = 1; i <= 5; i++)
    {
        for (j = 1; j <= 9; j++)
        {
            if ((j <= 5 - i) || (j >= 5 + i))
            {
                printf(" ");
            }
            else
            {
                printf("*");
            }
        }
        printf("\n");
    }
    for (i = 1; i <= 4; i++)
    {
        for (j = 1; j <= 9; j++)
        {
            if ((j <= i) || (j >= 10 - i))
            {
                printf(" ");
            }
            else
            {
                printf("*");
            }
        }
        printf("\n");
    }
    return 0;
}
