Calling a constructor to reinitialize variables doesn't seem to work?
- by Matt
I wanted to run 1,000 iterations of a program, so set a counter for 1000 in main. I needed to reinitialize various variables after each iteration, and since the class constructor had all the initializations already written out - I decided to call that after each iteration, with the result of each iteration being stored in a variable in main.
However, when I called the constructor, it had no effect...it took me a while to figure out - but it didn't reinitialize anything!
I created a function exactly like the constructor - so the object would have its own version. When I called that, it reinitialized everything as I expected.
int main()
{
Class MyClass()
int counter = 0;
while ( counter < 1000 )
{ stuff happens }
Class(); // This is how I tried to call the constructor initially.
// After doing some reading here, I tried:
// Class::Class();
// - but that didn't work either
/* Later I used...
MyClass.function_like_my_constructor; // this worked perfectly
*/
}
...Could someone try to explain why what I did was wrong, or didn't work, or was silly or what have you? I mean - mentally, I just figured - crap, I can call this constructor and have all this stuff reinitialized. Are constructors (ideally) ONLY called when an object is created?
