I'm trying to add all the square root answer but why am i getting this output: -858993430

#include <iostream.h>
void main()
{
int input;
int sqrt;
int i, sum, add;
cout << "Please enter your desire number: ";
cin >> input;
for (i=1; i <= input; i++)
{
sqrt = i * i;
add = sqrt;
cout << i << "^2 = " << sqrt<< "\n";
sum += add;
}
cout << "the sum is: " << sum;
}

what could be wrong? hope you could help me with this. thanks!

i got it! hmmm.... i cant use other than void... i'm not a pro yet and i must stick with the way my prof has taught us. though yah it would be nice to experiment from time to time but as now i have to stick with it :(. new ways are hard for me to understand especially when you have tones of assignments regarding it! hahaha!

but anyway, i appreciate it! thank a lot everybody!

so here's my code and glad to have it work... after how many paper scratches for computation.. :(

#include <iostream.h>
void main()
{
int input;
int sqrt;
int i, sum, add;
cout << "Please enter your desire number: ";
cin >> input;
cout << "\n" ;
for (i=1; i <= input; i++)
{
sqrt = i * i;
cout << "\n" << i << "^2 = " << sqrt<< "\n";
sum = sum + sqrt;
}
add = 0;
for (i=0; i <=input; i++)
{
sum = i * i;
add = add + sum;
}
cout << "\nThe sum is: " << add << "\n\n";
}

now my next problem is how to do the sum of powers from 1 to n :(
