覆寫C++的new與delete

#include <iostream>

#include <memory.h>

#include <stdlib.h>

using namespace std;

void* operator new(size_t num)

{

cout << "I'm operator new, i got num=" << num << endl;

return malloc(num);

}

void* operator new[](size_t num)

{

cout << "I'm operator new[], i got num=" << num << endl;

return malloc(num);

}

void operator delete(void* addr)

{

cout << "I'm operator delete, i got addr=0x" << hex << (long long)addr << endl;

return free(addr);

}

void operator delete[](void* addr)

{

cout << "I'm operator delete[], i got addr=0x" << hex << (long long)addr << endl;

return free(addr);

}

int main()

{

int* a = new int[10];

delete[] a;

return 0;

}
