Just introducing myself to TMPing, and came across a quirk
- by Justen
I was just trying to learn the syntax of the beginner things, and how it worked when I was making this short bit of code. The code below works in adding numbers 1 to 499, but if I add 1 to 500, the compiler bugs out giving me:
fatal error C1001: An internal error has occurred in the compiler.
And I was just wondering why that is. Is there some limit to how much code the compiler can generate or something and it just happened to be a nice round number of 500 for me?
#include <iostream>
using namespace std;
template < int b >
struct loop {
enum { sum = loop< b - 1 >::sum + b };
};
template <>
struct loop< 0 > {
enum { sum = 0 };
};
int main() {
cout << "Adding the numbers from 1 to 499 = " << loop< 499 >::sum << endl;
return 0;
}
