无法从const char []转换为std：string *

Question

In a visual c++ cli project file i created the following class (c++ type) . not able to declere a string or char type suitable for name variable.

#include <vector>
#include <string.h>
using namespace std ;

class MyClass 
{
public :
int x;
int y;
string * name;

void foo() { name = "S.O.S" ;}
};

Ps . type casting err

Answer 1

You need to make the following changes:

#include <string> // not <string.h>

class MyClass
{
public:
    int x;
    int y;
    string name; // not string*
};

EDIT:

To address comments by eliz , a small example:

#include <iostream>
#include <string>

using namespace std;

class MyClass
{
public:
    int x;
    int y;
    string name;

    string foo()
    {
        name = "OK";
        return name;
    }
};

int main()
{
    MyClass m;

    // Will print "OK" to standard output.
    std::cout << "m.foo()=" << m.foo() << "\n";

    // Will print "1" to standard output as strings match.
    std::cout << ("OK" == m.foo()) << "\n";

    return 0;
}

If name is of type string * , then you must call one of the string constructors.

name = new string("S.O.S");

And don't forget to release your string in the destructor (~MyClass())!
