C program to Diamond pattern program

In this article, we will discuss the programming concept of C program to Diamond star pattern program

we can create star number, alphabet, binary patterns using loops (for, while and do-while loop) in C language

In this post, we are going to learn how to create a diamond pattern in C language using the given symbol

C code to the Diamond pattern using for loop

This program allows the user to enter the number of rows and the symbol then the program displays the diamond pattern with the given symbol using for loop in C language

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j,Num_Of_space=1;
    char ch;
    printf("Enter number of rows\n");
    scanf("%d%c",&rows,&ch);
    printf("Enter the symbol as you wish:");
    scanf("%c",&ch);
    Num_Of_space=rows-1;

    for(i=1; i<=rows; i++){
        for(j=1; j<=Num_Of_space; j++)
            printf(" ");
            Num_Of_space--;

        for(j=1; j<=2*i-1; j++)
            printf("%c",ch);

        printf("\n");

    }

    Num_Of_space=1;
    for(i=1; i<=rows-1; i++){
            for(j=1; j<=Num_Of_space; j++)
            printf(" ");
    Num_Of_space++;

        for(j=1; j<=2*(rows-i)-1; j++)
            printf("%c",ch);
            printf("\n");

        }
        getch();

    return 0;
}

When the above code is executed, it produces the following result

C code to Diamond using while loop

This program allows the user to enter the number of rows and the symbol then the program displays the diamond pattern with the given symbol using while loop in C language

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j,Num_Of_space=1;
    char ch;
    printf("Enter number of rows\n");
    scanf("%d%c",&rows,&ch);
    printf("Enter the symbol as you wish:");
    scanf("%c",&ch);
    Num_Of_space=rows-1;
i=1;
    while(i<=rows){
            j=1;
        while(j<=Num_Of_space){
            printf(" ");
     j++;
        }
            Num_Of_space--;
j=1;
        while(j<=2*i-1){
            printf("%c",ch);
             j++;
        }
        printf("\n");
 i++;
    }

    Num_Of_space=1;
      i=1;
    while(i<=rows-1){
j=1;
            while(j<=Num_Of_space){
            printf(" ");
             j++;
            }
    Num_Of_space++;
j=1;
        while( j<=2*(rows-i)-1){
            printf("%c",ch);
            j++;
        }
            printf("\n");

 i++;
        }
        getch();

    return 0;
}

When the above code is executed, it produces the following result

C code to Diamond using the do-while loop

This program allows the user to enter the number of rows and the symbol then the program displays the diamond pattern with the given symbol using the do-while loop in C language

Program 3

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j,Num_Of_space=1;
    char ch;
    printf("Enter number of rows\n");
    scanf("%d%c",&rows,&ch);
    printf("Enter the symbol as you wish:");
    scanf("%c",&ch);
    Num_Of_space=rows-1;
i=1;
    do{
            j=1;
        do{
            printf(" ");
     j++;
        }while(j<=Num_Of_space);
            Num_Of_space--;
j=1;
       do{
            printf("%c",ch);
             j++;
        } while(j<=2*i-1);
        printf("\n");
 i++;
    }while(i<rows);

    Num_Of_space=1;
      i=1;
    do{
j=1;
            do{
            printf(" ");
             j++;
            }while(j<=Num_Of_space);
    Num_Of_space++;
j=1;
        do{
            printf("%c",ch);
            j++;
        }while( j<=2*(rows-i)-1);
            printf("\n");

 i++;
        }while(i<rows);
        getch();

    return 0;
}
