String initialization in C++
Hi Experts,
In C, if you want to initialize a char string you would set it to null. But, in C++ string how do I do it? I think C++ string doesn't terminate on null character.....
char * myStr = "\0";

When you construct an object of the std::string class from the standard library, it is empty by default, so if that's what you want, you need not do any more to initialize it. If you want to get rid of the content of a string, you can use the clear function as Akumas showed, except you need parentheses:
myStr.clear();
myStr.clear();
btw, instead of this :
char * myStr = "\0";
this is sufficient :
char * myStr = "";
The '\0' character is automatically appended by using "" for initialising.
char * myStr = "\0";

char * myStr = "";

initialize:
#include <string>
using std::string;
sttring myStr;//initialized
myStr = "some contant";//assign value
myStr.clear;//clear content in vc7 and above
myStr = "";//clear content in vc6
const char* cStyle = myStr.c_str();//get c style str
