 |
|
Does the latest C++ standard support the following codes without any
warning:
struct unknown {
const int i;
const char str[4];
}
This will gave me a compilation error several years ago. If this is
supported now, what's the right way of initialization?
Thanks in advance.

Well the only error is the omission of the terminating semicolon so I
cannot imagine why you ever had a problem.

#include <iostream>
#include <string>
struct unknown {
const int i;
const char str[4];
};
int main(){
unknown uk = {3, "abc"};
std::cout << uk.i << ' ' << uk.str <<'n';
}
However you can only currently use the assignment style initialisation
syntax for brace initialisers. That is one of the things I want to
change in a future C++ Standard.
