String Functions

[Alan777]

I'm totally new to C++. Any help is very much appreciated

Can someone kindly give me C++ equivalents for the following VBA library functions:


Left <<< Solved
Right <<< Solved
Mid <<< Solved
InStr <<< Solved
InStrRev
Len <<< Solved
Trim

Looks like by the time someone answers I'll have solved them all myself

also, how do you make an array of Strings, or do you have to make a 2 dimensional char array for this?

Different classes have different methods. String, Cstring and regular char, are the basic ones.

C isn't like VB. If you are working on base types like char, you pretty much have only a few string operators available - you get to write your own for most things like LTRIM. String and Cstring have left and right, and so on.

Go into C++ help, look up string or strcpy. There are a lot of basic string operators. The same applies for String (with a capital S).

I can remeber at least 3 times someone asked this. Search the forum for trim.

string left(const string &s, size_t len) {
    return s.substr(0, len);
}

...or is it (1, len)?...
