Question

In the sample code below

    std::string result = exec( "dir" ) ;
    cout<<result;

I get the following error

error C2679: binary ‘<<‘ : no operator defined which takes a right-hand operand of type ‘class std::basic_string

I suspect there is a special method to print out an std::string.

Please help me debug this.

Also, I have included iostream.h, fstream.h and stream header files.

Answer 1

Answering my own question on behalf of @MrLister since he was inactive.

I should have included <iostream> and <fstream> without .h. Also using namespace std; should have been typed after that.

Ex:

#include <string>
#include <iostream>
#include <fstream>
#include <stdlib>

using namespace std;

Many many thanks to @MrLister.

And thanks to @dasblinkenlight. His answer enhanced a little bit.
