[Solved] Best way to call a function C++ [closed]

by


It depends on the return value of the function.

If this is void the function does not have a return value and you do the first.

callOne(1, 2);

If it has something else like int, char or std::string you can use the first but also the second.

callTwo = func2(5, 9);

In this case you save the value the function returns in the variable.

If you use the first variant on a function with return value (not void) the result will be ignored.

I would advice you to google for some basic tutorials like this or this for example. You won’t be very fast if you let SO teach you basic things.
