Declaring strings as std:string in C++

Question

This is based on GCC/G++ and usually on Ubuntu.

Here\'s my sample program I\'ve done:

#include 

using namespace std;

int main()
{
          


        

Answer 1

You need to include the string class header:

#include 

This code has a typo, missing a second colon

std:string N;

should be:

std::string N;

With a single colon, it becomes a label for goto, which is probably not what you meant.
