Thread: Converting a string to a character array

Better yet, if you don't want a const char* use the copy() function:

Code:

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

int main()
{
string s;
char* buf;
s = "THIS IS A STRING";
buf = new char[s.size()+1];
s.copy(buf,s.size());
cout<<buf;


}

copy takes two or three parameters:

copy(char* buf, int len);
copy(char* buf, int len,int startpos);

It copies at most len characters into the buffer, and with the second function starts copying with a certain character in the std::string...It doesn't null terminate the char* so take that into account

Note: You could also simply use data() which works like c_str() (returns an array of chars) but doesnt append a Null character
