How can I transfer string to char* (not const char*)

Question

I wanna do something like:

string result;
char* a[100];
a[0]=result;

it seems that result.c_str() has to be const char*. Is there any way to do this?

Answer 1

You can take the address of the first character in the string.

a[0] = &result[0];

This is guaranteed to work in C++11. (The internal string representation must be contiguous and null-terminated like a C-style string)

In C++03 these guarantees do not exist, but all common implementations will work.
