Why can't I change regVar?

Question

class MyClass {
public:
MyClass(int a, int b);
private:
int regVar;
const int constVar;
};

MyClass::MyClass(int a, int b)
: regVar(a), constVar(b)
{
regVar = 5;
cout << regVar << endl;
cout << constVar << endl;
}

int main() {
MyClass obj(42, 33);
}

Answer 1

The last assignment to regVar is 5 so it will result in the output with value 5.
What is that you didn't understand?

Answer 2

I tested your code in Code Playground and it runs just fine and outputs as expected.

Answer 3

lol.. thanks a lot you both. It didn't work when I tried.

Answer 4

The program don't run. Why can't I change regVar value to 5 in that way? As it's not declared constant, it should be changed isn't it?
