hi,
i have two questions:
1. How to convert from string to char*? I use c_str() of string, but
it returns "const char*" instead of char*;
One way is to create a char array and copy from c_str() to it.
2. When i use copy() function of string, i always get some unknown
characters from the first parameter (char*) after using copy()
function.(these unknow character is like "<<" or ">>", but my string
doesn't include these characters.)
Using copy won't nul-terminate the string, so you will get junk characters
after the characters you copy. If you use this approach, then you need to
nul-terminate manually. If this doesn't solve the problem, then post
(compileable) code showing what you are doing.
