Introduction
The program shows the sum of squares of n numbers. By using the formula (n*(n+1)*((2*n)+1))/6 sum of squares of numbers can be calculated. 1^2+2^2+3^2....
#include<stdio.h> #include<conio.h> void main() { int a,n; clrscr(); printf("/n Enter a number:"); scanf("%d",&n); a=(n*(n+1)*((2*n)+1))/6; printf("sum of squares of numbers upto %d is %d",n,a); getch(); }
Comments/Suggestions are invited. Happy coding......!
