#include <stdio.h>
void increment(int num) {
num++;
printf("Inside Function: %d\n", num);
}
int main() {
int value = 10;
increment(value);
printf("Inside Main: %d\n", value);
return 0;
}Coding works best on desktop or with an external keyboard.
Demonstrates call by value, where a copy of the actual argument is passed to the function. Changes made inside the function do not affect the original variable.

}
int main() {
int value = 10;

}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.
