Pyramid Problem No. 36

 Q. 36 Write a C program to display the following number rhombus structure:

     1
    121
   12321
  1234321
   12321
    121
     1

Solving in C:

    #include <stdio.h>
    int main(){
        int row,col;
        for(row=1;row<=4;row++){
            for(col=1;col<=4-row;col++) printf(" ");
            for(col=1;col<=row;col++) printf("%d",col);
            for(col=row-1;col>=1;col--)printf("%d",col);
            printf("\n");
        }
        for(row=4-1;row>=1;row--){
          for(col=4;col>=row+1;col--) printf(" ");
          for(col=1;col<=row;col++) printf("%d",col);
          for(col=row-1;col>=1;col--)printf("%d",col);
            printf("\n");
        }
    
        return 0;
    }
