Here’s my gcc

Whenever i try to compile code, say this simple program called test:

#include <iostream>
using namespace std;
int main() {
    cout << "Hello, World!" << endl;
    return 0;
}

If i compile using: g++ -m64 -o test.exe test.cpp
And then try to run from cmd, i get this error:

While if i compile using: g++ -m32 -o test.exe test.cpp
it runs just fine.

What’s the issue here?
