#Whitespace, (looks like C++)

I don't know if this qualifies, but I thought it was fun

raw paste data here.

online interpreter here.

#include<iostream>               

int main() {                
    std::cout<<2+2;
             

                    

    return  0;      



}

If you run it in C++ it prints

4

If you run in whitespace it prints

2+2=5
