Which C++ string function returns nth character of the string?

Mar 28th, 2008

This has been driving me nuts for the last half hour or so. Google didn't help. I don't know which function returns the nth character in the string. I know that it is supposed to be something like this

stringname.something(n?)

If someone could post the function and an example of how to use it, I would really appreciate it.

there is no string data type in c++... the string u enter is in char array.... so u already have the access to any index element in the c++ string

If you are using char[] array or STL strings, just use the [] operator. e.g.

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
#include <string>
using namespace std;
...
string mystring = "hello";
v = mystring[n]; // v = nth character of string
 
// or
char mycharstring = "hello";
v = mycharstring[n]; // v = nth character of string
#include <string>
using namespace std;
...
string mystring = "hello";
v = mystring[n]; // v = nth character of string

// or
char mycharstring = "hello";
v = mycharstring[n]; // v = nth character of string
