error C2143 missing ';'...

Hi all,

i am using Microsoft Visual C++ 2010 Express

i am sure, a super easy question. i am just learning C++...and i am already stuck with this error...here the simple program

Code:

---

#include <iostream>
using namespace std;
int main()
{
    int ai {5}; // Error : Missing ';' before {
    cout << ai;
    return 0;
}

---

i admit i never used such initialisation and never heard of it so far, i used to write

Code:

---

int ai = 5

---

why is the compiler complaining.

The syntax you're trying to use was introduced in the 2011 edition of the C++ standard, i.e., your compiler is too old.

oook. Understood. thanks.

is there an advantage of the new syntax again the old one?

It's a bit old and so might be outdated for C++14 and C++17 as I vaguely recall some technical change in this area, but it's still a good overview: GotW #1 Solution: Variable Initialization – or Is It?
