C++ equivilant of Basic MID$

Question:
I need to test for a certain char in a char array. For example, in BASIC I would have:
if mid$(string,1,1) = "`" then
 blah blah blah....

How would I do this in C/C++? Note: I'm still new to C++ :P Compiler == Turbo C++ 3.0(Dos)

Answer:
Normally, you could just use:

   if (string[0] == '`') ...
This assumes that string is a character array (or pointer to a character array) and is much more efficient than BASIC's Mid$ function. (Note that the index for the first character is 0 and not 1).

If you are using a string class, the syntax might be a little different, but all good string classes provide a syntax for accessing individual characters and it often looks the same as that for character arrays.
