}Coding works best on desktop or with an external keyboard.
Demonstrates call by reference by passing the memory address of a variable to a function using pointers. Changes made inside the function affect the original variable.
#include <stdio.h>
void increment(int *num) {
(*num)++;

int main() {
int value = 10;
increment(&value);
printf("Updated Value: %d\n", value);

}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.
