C program to find the sum of squares of first n natural numbers

Here is a simple C program to find the sum of squares of first n natural numbers using do-while looping construct –

main(){
             int n, sum =0;
   
             printf("\nInput any integer of your choice>>");

             scanf("%d",&n);

             nsave = n;

             do{                
                sum += n*n;
                n--;
             }
             while(n > 0);

             printf("Sum of squares upto %d = %d \n", nsave, sum);
      }
