How to create a memory leak in C++?

Question

I was just wondering how you could create a system memory leak using C++. I have done some googling on this but not much came up, I am aware that it is not really feasible t

A memory leak occurs when you call new without calling a corresponding delete later. As illustrated in this sample code:

int main() {
    // OK
    int * p = new int;
    delete p; 

    // Memory leak
    int * q = new int;
    // no delete
}
