#include <stdio.h>
int factorial(int n) {
if (n == 0)
return 1;
return n * factorial(n - 1);

int main() {
printf("Factorial = %d\n", factorial(5));

}Coding works best on desktop or with an external keyboard.
Demonstrates recursion by creating a function that calls itself. Shows how a recursive function solves a problem by reducing it to smaller subproblems until a base case is reached.
#include <stdio.h>
int factorial(int n) {
if (n == 0)
return 1;
return n * factorial(n - 1);

}C is a general-purpose, procedural programming language that provides low-level access to memory, efficient performance, and a foundation for system and application software development.
Origin & Creator
Created by Dennis Ritchie at Bell Labs in 1972, originally for developing the UNIX operating system.
Industrial Note
C is essential in embedded systems, OS kernels, compilers, device drivers, and performance-critical applications where low-level memory control and speed are required.
