Using strcat in C

Question

Okay so I have the following Code which appends a string to another in C#, note that this is Just an example, so giving alternative string concatination met

Answer 1

As said previously, you have to write to a sufficiently large buffer. Unfortunately, doing so is a lot of extra work. Most C applications that deal with strings use a dynamically resizable string buffer for doing concatenations.

glib includes an implementation of this, glib strings, which I recommend using for any application that uses strings heavily. It makes managing the memory easier, and prevents buffer overflows.
