Every variable in C language has a name and a value associated with it. When a variable is declared, a specific block of memory within the computer is allocated to hold the value of that variable.

Every computer has a primary memory. All data and programs need to be placed in the primary memory for execution. RAM is a collection of memory locations (often known as cells) and each location has a specific address.

Recursion is more of a top-down approach to problem solving in which the original problem is divided into smaller sub-problems.

The tower of Hanoi is one of the main applications of recursion. It says, 'if you can solve n-1 cases, then you can easily solve the nth case'.

Subject and UNIT: Programming in C: Unit III (a): Functions
Recursion is a technique that breaks a problem into one or more sub-problems that are similar to the original problem.
Syntax with Example C Programs
Subject and UNIT: Programming in C: Unit III (a): Functions
A recursive function is defined as a function that calls itself to solve a smaller version of its task until a final call is made which does not require a call to itself.

Storage class defines the scope (visibility) and lifetime of variables and/or functions declared within a C program. In addition to this, the storage class gives the following information about the variable or the function.
Block, Function, Program, File Scope | Programming in C
Subject and UNIT: Programming in C: Unit III (a): Functions
In C, all constants and variables have a defined scope. By scope we mean the accessibility and visibility of the variables at different points in the program.

When a function is called, the calling function may have to pass some values to the called function. We have been doing this in the programming examples given so far.

Subject and UNIT: Programming in C: Unit III (a): Functions
The return statement is used to terminate the execution of a function and returns control to the calling function.
with Example C Programs
Subject and UNIT: Programming in C: Unit III (a): Functions
The function call statement invokes the function. When a function is invoked the compiler jumps to the called function to execute the statements that are part of that function.

When a function is defined, space is allocated for that function in the memory. A function definition comprises two parts:Function header,Function body
