String Handling Functions in C (string.h)

Because strings in C are just arrays of characters, standard operations like copying a string or finding its length are not as simple as typing stringA = stringB. You cannot use standard mathematical operators on arrays!

To solve this, C provides a standard library dedicated entirely to string manipulation. To use these functions, you must include the <string.h> header file at the top of your program.

Let's look at the four most important string functions that you will use constantly.
