Below are several short tips which will help you survive C programming.
The most terrifying aspect of the C programming language is closely related to it’s core strength. Programming in C is all about using pointers – which are memory locations. Thus, in C, when you need a variable to work with to store numbers and manipulate them, you don’t have to deal with the variable directly – you use it’s address, instead. This is, of course, a really stupid thing to do when you just have to use a single variable to store a single number. But it is an enormously useful strategy when sending that variable off to a distant procedure, or when dealing with large arrays.
