Recursion is a programming technique where a function calls itself directly or indirectly in order to solve a problem. It allows a function to repeat itself several times, reducing the problem size with each iteration, until it reaches a base case where a direct solution can be obtained without further recursion. Recursion is commonly used in problems that can be broken down into smaller, similar subproblems.
Here’s a classic example of recursion: calculating the factorial of a number.
In mathematics, the factorial of a non-negative integer
�
n is denoted by
�
!
n! and is the product of all positive integers less than or equal to
�
n.
The factorial function can be defined recursively as:
\begin{cases}
1 & \text{if } n = 0 \\
n \times (n-1)! & \text{if } n > 0
\end{cases} \]
Let’s implement this factorial function recursively in C:
“`c
#include
// Function prototype
int factorial(int n);
int main() {
int num;
printf(“Enter a non-negative integer: “);
scanf(“%d”, &num);
// Call the factorial function
int result = factorial(num);
printf(“Factorial of %d is %d\n”, num, result);
return 0;
}
// Recursive function to calculate factorial
int factorial(int n) {
// Base case: factorial of 0 is 1
if (n == 0) {
return 1;
}
// Recursive case: n! = n * (n-1)!
else {
return n * factorial(n – 1);
}
}
“`
Explanation of the code:
– `factorial(int n)`: This is the recursive function that computes the factorial of `n`.
– Base Case: `if (n == 0)`: If `n` is 0, the function returns 1 because \( 0! = 1 \).
– Recursive Case: `else`: If `n` is greater than 0, the function recursively calls itself with `n-1` until it reaches the base case.
When you run this program and enter a non-negative integer, the program will compute its factorial using recursion. For example, entering 5 would output:
“`
Enter a non-negative integer: 5
Factorial of 5 is 120
“`
This demonstrates how recursion works by breaking down the factorial calculation into smaller subproblems (calculating `(n-1)!` in each step) until it reaches the base case (factorial of 0).

A pointer is a variable in programming that stores the memory address of another variable. In simpler terms, it “points to” the location of another variable in memory rather than storing a value directly. Pointers are fundamental in languages like C, C++, and other low-level languages where direct memory manipulation and efficiency are important.
Here’s an example in C:
#include
int main() {
int num = 10; // declaring an integer variable
int *ptr; // declaring a pointer variable
ptr = # // assigning the address of num to ptr
printf(“Address of num: %p\n”, &num); // printing the address of num
printf(“Value of ptr: %p\n”, ptr); // printing the value of ptr (which is the address of num)
printf(“Value at ptr: %d\n”, *ptr); // printing the value at the address stored in ptr
return 0;
}
Explanation of the example:
int num = 10;: Defines an integer variable num with a value of 10.
int *ptr;: Declares a pointer ptr to an integer (int * denotes a pointer to an integer).
ptr = #: Assigns the address of num to ptr using the address-of operator (&).
printf(“Address of num: %p\n”, &num);: Prints the address of num using %p format specifier.
printf(“Value of ptr: %p\n”, ptr);: Prints the value stored in ptr, which is the address of num.
printf(“Value at ptr: %d\n”, *ptr);: Prints the value at the address stored in ptr using the dereference operator (*ptr), which accesses the value at the memory address ptr points to (num in this case).
In this example, ptr is a pointer that “points to” the variable num, allowing us to indirectly access and manipulate num through ptr. Pointers are powerful tools for efficient memory management and data manipulation in programming languages that support them.
