Square And Rhombus Star Pattern

 Square And Rhombus Star Pattern

In this topic, we will learn how to create the patterns by using C language. We will create the patterns by using either a '*' star character or some other character. We will create different patterns or a geometrical shape such as triangle, square, rhombus etc.

Square Star Pattern Program

C Program

//Square Star Pattern
#include <stdio.h>  
 int main()  
{  
    int n;  
    printf("Enter the number of rows: ");  
    scanf("%d",&n);  
    for(int i=0;i<n;i++)  
    {  
        for(int j=0;j<n;j++)  
        {  
            printf("*");  
        }  
        printf("\n");  
    }
 return 0;
}

Hollow Square Star Pattern Program

C Program

//Hollow Square Star Pattern
#include <stdio.h>  
int main()  
{  
    int n;  
    printf("Enter the number of rows: ");  
    scanf("%d",&n);  
    for(int i=1;i<=n;i++)  
    {  
        for(int j=1;j<=n;j++)  
        {  
            if(i==1 ||i==n||j==1||j==n)  
            {  
            printf("*");  
            }  
            else  
            printf(" ");  
        }  
        printf("\n");  
    }  
      
    return 0;  
}

Hollow Square Star Pattern With Diagonal Program

C Program

//Hollow Square Pattern with Diagonal
#include <stdio.h>  
int main()  
{  
    int n;  
    printf("Enter the number of rows: ");  
    scanf("%d",&n);  
    for(int i=1;i<=n;i++)  
    {  
        for(int j=1;j<=n;j++)  
        {  
            if(i==1 ||i==n||j==1||j==n-i+1||i==j||j==n)  
            {  
            printf("*");  
            }  
            else  
            {  
                  
                      printf(" ");  
                  }  
                 
            }        
        printf("\n");  
    }  
      
    return 0;  
}
