Access violation reading location without location

Question

Well, i have two functions

void RealFunction()
{
    MessageBox(NULL, "RealFunction()", "Trace", MB_OK);
}

void FakeFunction()
{
    MessageBox(NULL, "FakeFunction()", "Trace", MB_OK);
}

and when i try to do that i get access violation error

void main()
{
    DWORD target = (DWORD)RealFunction;
    DWORD trampoline = (DWORD)Trampoline;
    cout << target + " - " + trampoline << endl;
}

I don't know why it is even throwing access violation while i am trying to cout a DWORD ?

Answer 1

DWORD target = (DWORD)RealFunction;
DWORD trampoline = (DWORD)Trampoline;
cout << target + " - " + trampoline << endl;

You must've meant << instead of + .

You have a const char * , the string literal containing a dash. To that, you're adding two, likely fairly large numbers, with the result being some absurd memory address, which is interpreted as a string pointer. Undefined behavior.
