Thread: pointer to string???

this is normal pointer that gives variable that var contains

Code:

#include <iostream>
#include <string>
using namespace std;

int main ()
{
    int var = 0;
    cout << var << endl;
    int * pointer1 = &var;
    cout << *pointer1 << endl;
    
    int g;
    cin >> g;
    return 0;
}

it's all the same I have just put string instead of int

Code:

#include <iostream>
#include <string>
using namespace std;

int main ()
{
    string var = 0;
    cout << var << endl;
    string * pointer1 = &var;
    cout << *pointer1 << endl;
    
    int g;
    cin >> g;
    return 0;
}

1. I don't get compiler error
the program starts and ends very fast why???

what does program exactly do now??

or how to point to string???

You can't assign a number to a string variable. Try something like this:

Code:

string var = "a string";

use std::stringstream or itoa / ftoa to convert numeric types to ascii.

You can use an empty string.

If an empty string won't work with what you're doing, then you'll have to find some other solution. One option is a separate bool that holds the true or false value you want to keep. If the information is complicated enough you would combine these into a struct or class and provide methods to handle the behavior.

sorry I have edit the message

yes I found the solution to that message you saw

I used bool and works fine for 0 or flase
