with keyword in Pascal can be use to quick access the field of a record.
Anybody knows if C++ has anything similar to that?
Ex: I have a pointer with m
A simple way to do this is as follows
class MyClass
{
int& m_x;
public MyClass(int& x)
{
m_x = x;
m_x++;
}
~MyClass()
{
m_x--;
}
}
int main():
{
x = 0;
{
MyClass(x) // x == 1 whilst in this scope
}
}
I've been writing python all day long and just scrapped this down before anyone takes me to the cleaners. In a larger program this is an example of how to keep a reliable count for something.
