Pyramid Problem No. 35

 Q. 35 Write a C program to display the following number rhombus structure:

     1
    212
   32123
  4321234
   32123
    212
     1

Solving in C:

    #include <stdio.h>
    int main(){
        int row,col;
        for(row=1;row<=4;row++){
            for(col=4;col>=1;col--){
                if(col>=row+1) printf(" ");
                else printf("%d",col); }
            for(col=2;col<=row;col++)printf("%d",col);
            printf("\n");
        }
        for(row=4-1;row>=1;row--){
          for(col=4;col>=1;col--){
                if(col>=row+1) printf(" ");
                else printf("%d",col); }
            for(col=2;col<=row;col++)printf("%d",col);
            printf("\n");
        }
    
        return 0;
    }
