}Coding works best on desktop or with an external keyboard.
Demonstrates the use of increment (++) and decrement (--) operators. Shows the effect of pre-increment, post-increment, pre-decrement, and post-decrement on variable values.

}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.
