Thread: I don't understand this error...

Okay I'm just writing a short piece of code to figure out a math problem

Code:

#include <iostream.h>

void main() {
	int num;
	int num2;
	int sum=0;

	cout<<"Enter num: ";
	cin>>num;
	
	num2=num*2;

	for (int i=1; i<num2; i++) {
		if (num2%i==0 && num%i!=0) {
			sum+=i;
		}
	}

	cout<<sum<<endl;
}

It compiles fine but it gives me the runtime error up to the part that inputs the data then crashes. Similary if i just put 1 statement in the main like "cout<<"blah"<<endl; then it still crashes:

Code:
