Initialization difference with or without Curly braces in C++11

Question

We can initialize the variable in two ways in C++11

One:

int abc = 7;

Two:

int ab         


        

Answer 1

While for int the existing replies are complete, I painfully found out, that in some cases, there are other differences between the () and {} initializations.

The keyword is that {} is an initializer list.

One such cases is, the std::string initialization with count copies of a char:

std::string stars(5, '*')

will initialize stars as *****, but

std::string stars{5, '*'}

will be read as std::string stars(char(5), '*') and initialize star as * (preceded by an hidden character).
