convert C++ string to C character array.

hello, i realy can't figure this out. i have tried to search, but i cant find any topics to match "convert string to string" :rolleyes:
here is what i tired:

Code:

---


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

int main()
{
string stra;
char strb[100];
int mim;
stra = "test";
mim = (int)stra;
strcpy(strb, (char)mim);
}

---

i thought this code might work.. but doesn't, i thought it would 'trick' the compiler. heh

Code:

---

std::string MyString = "Yo world!";
char MyCharArray[1024];
strcpy(MyCharArray, MyString.c_str());

---

YAY!
thanks a lot.
i really appreciate it.

and it was so simple!
is there some website that lists all the standard functions?

try www.cppreference.com :)

thank you :)

just one more question.
when i use 'getline(cin, string)' i input the string, then press return, and it only inputs the string after i press return twice?
why?

>and it only inputs the string after i press return twice?
You probably use Microsoft Visual C++ 6. That's a bug in the getline source code.

yes!
i have always tried to avoid using getline(), but now i can use it. Thank you
prelude, you realy are a great member at this forum, keep up the good helping! :)

ok, sorry, i know this is a completely different question (again...) but i didn't see the point in opening another thread, when i already had a recent one.

but anyway..

Code:

---

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

int main()
{
        string x="hello world";
        cout << x[1];

}

---

this works fine, but if i wanted to input a character like:

Code:

---

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

int main()
{
        string x;
        cin >> x[1];
                cout << x[1];

}

---

it doesn't work, why not?
i see no reason for it not to work?

>string x;
This creates an empty string.

>cin >> x[1];
This references x[1], but does x[1] exist in an empty string?

Try this:

Code:

---

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

int main()
{
    string x="hello world";
    cin >> x[1];
    cout << x[1];
}

---

That works fine. The reason is because the string has a size. In your example that didn't work, you tried to change the second letter of an empty string. That is undefined behavior. You must make sure the string is big enough to access the character at the position you are trying to read into. You could also use x.resize(2) to make the size larger. I don't remember if that fills the string with null characters or spaces, but it seemed to work in my quick test.

*bows* thanks
