C program to Display diamond number pattern using while loop

C program to Display diamond number pattern using while loop

In this tutorial, we will discuss the concept of the C program to Display diamond number pattern using while loop

In this post, we will learn how to make different diamond number pattern using while loop in C language

 

We can use for loop, while loop or do while loop to display different diamond Number patterns.

Here, we will use while loop to print diamond Number patterns in C language.

 

The following C program requests the user to enter the number of rows as the user wanted and the program will display the number of rows in diamond number pattern according to the user input

 

Program 1

diamond number pattern 1

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

int main()
{
    int rows;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    int row=1,i,j,k;
i=1;
while(i<=rows){    //print upper part
    for(j=1; j<=rows-i; j++){
      printf(" ");//print space
}
k=1;
while(k<=i){
      printf("%d",k);//print number to upper part
      printf(" ");
       k++;
}
printf("\n");
 i++;
}

i=1;
while(i<=rows-1){  //print lower part
        j=1;
    while(j<=i){
      printf(" ");//print space
 j++;
}

k=1;
while(k<=rows-i){
      printf("%d",k);//print num ber to lower part
      printf(" ");
       k++;
}
printf("\n");//move to next line
 i++;
        }
getch();
return 0;
    }

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

 

Enter the number of rows: 6
         1
       1  2
     1  2  3
   1  2  3  4
  1  2  3  4  5
1  2  3  4  5  6
  1  2  3  4  5
    1  2  3  4
      1  2  3 
        1  2
          1

 

Program 2

diamond number pattern 2

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

int main()
{
    int i,j,k,l,rows;
    printf("|Enter the number of rows");
    scanf("%d",&rows);
    i=1;
    while(i<=rows){    //print upper part
            j=1;
    while(j<=rows-i){
      printf(" ");//print initial space for upper part
     j++;
}
k=i;
while(k>=1){
      printf("%d",k);
       k--;
}
l=2;
while(l<=i){
      printf("%d",l);
       l++;
}
printf("\n");
 i++;
}

i=rows-1;
while(i>=1){  //print lower part
        j=0;
     while(j<=rows-1-i){
     printf(" ");//print initial space for lower part
 j++;
}
k=i;
while(k>=1){
      printf("%d",k);
       k--;
}
l=2;
while(l<=i){
      printf("%d",l);
       l++;
}
printf("\n");
 i--;
        }
    return 0;
}

 

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

Enter the number of rows: 6
          1
        212
      32123
    4321234
  543212345
65432123456
  543212345
    4321234
      32123
        212
          1

 

Program 3

diamond number pattern 3

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

int main()
{
    int rows,i,j;
    int row=1;
   printf("Enter the number of rows: ");
scanf("%d",&rows);
i=rows/2;
while(i>0){    //print upper part
        j=1;
    while(j<=i){
      printf(" ");
 j++;
}
j=1;
while(j<=row){
      printf("%d",row);
      printf(" ");
       j++;
}
printf("\n");
row++;
 i--;
}

i=0;
while(i<=rows/2){
        j=1;
  while(j<=i){
      printf(" ");
 j++;
}

j=row;
while(j>=1){  //print lower part
      printf("%d",row);
      printf(" ");
       j--;
}
printf("\n");
row--;
 i++;
        }
        getch();
    return 0;
}

 

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

Enter the number of rows: 8
        
             1
          2   2
       3   3   3
     4  4   4   4
  5  5   5   5   5
     4  4   4   4  
       3   3   3
          2   2
             1
