no it will not work...


try this...


Constructor() : x(value) { }
Reply:there is no such thing as a constant variable, its either one or the other.


if you want it to be a constant, then you just say


const int x = 4;


the way you have your code written, it wouldnt be a constant, it would be a variable, so you would just declare it as


int x;
