Tutorial 4

An array is a collection of similar data types stored in contiguous memory locations that can be accessed using an index. Strings are arrays of characters that can be manipulated using functions like strcat to concatenate, strcmp to compare, and strstr to search. User-defined functions allow programmers to define reusable blocks of code. Functions are categorized based on return type and parameters, with actual parameters passed during a call corresponding to formal parameters defined in the function header. Recursive functions call themselves during execution, while global variables are accessible from anywhere in a program and local variables are only accessible within the function they are declared.
