C Programming

Introduction to Programming

• Programming is the process of writing some instructions (software) for computers to follow
• Computers only understand binary (0 and 1), also known as machine language
• Machine code (language) is difficult to remember and is quite lengthy, even for small operations

Setting up the Work Environment

• Compiler This is a software that converts our source code into computer understandable code
• This is a software that creates an executable file from the object code created by the compiler

Exploring the IDE

• This IDE works with many languages
• Can create projects which will include related files
• Excellent debugging tools
• Easy to use interface

Objective

• A pointer stores the address (memory location) of another entity
• Address-of operator (&) gets the address of an entity
• De-reference operator (*) makes a reference to the value at the address stored by the pointer
• Pointer and array
• Pointer arithmetic
