Hi . new to C++
have a var. that is called password, password could contain 1-10 char. I would like to find out how many char's password contains

Try the function strlen.

length = strlen(password);
should do it.

More better use STL string class from <string>:

#include <string>
...
string psw;
...
... psw.length()...

I like to use the CString class since the variables cannot overflow the allocated memory. Over the last twenty years, I have exceeded the defined length of a variable way too many times.

CString also has a function for obtaining the length of the string.
