How to initialize data members using a constructor in a c++ program?

Question

if the constructor is initialized within public of a class and the input of data members of the class is being done at the main function. what is the right way to do it?
an example with a program would be helpful.

Answer 1

myClass(string newName) : name(newName) { }

is also acceptable.. (Using everything else from the example provided by luka)

Answer 2

naww i like the () way it seems alot cleaner... dang standards lol

Answer 3

in c++11 we use these {} for initialising, but it's also okay to use (), tho it's not standard anymore

Answer 4

thanks everyone for helping out.
