C Programming the Basics

Explore the basics of the C programming language, its close-to-hardware, memory management focus, and its progression from machine language and assembly through high-level languages, taught by examples.

Learn to run C code using online compilers or a local tool like Visual Studio Code. Understand that a compiler turns C code into an executable you can run.

Create a hello world program by including stdio.h, defining main, and using printf to output text with newline characters.

Explore data types in c, from characters and text to integers and doubles, declare types explicitly, and print values with printf using %d, %f, %c, and %s with newlines.

Explore arithmetic in C with stdio and printf, covering integers and floating-point numbers, operators + - * /, format specifiers, and the effects of integer division.

Learn to compare values in C using if statements, equality with ==, and logical and with && to test A, B, and C, with else and else if for branching.

Define and call functions, pass parameters, and return values in C. Create named functions, invoke them from main, and store results in variables like x for later use.

Discover how arrays in C programming basics hold numbers, characters, or text, with a fixed size, zero-based indexing, and loops that print each item with its index.

Master for loops in C to repeat code with a start and end. Use index variables and plus plus or plus equals for stepping, including inclusive versus exclusive ends.

Learn how to read characters from the keyboard and output them in C using getchar and printf, then handle multi-character input with buffers while managing memory allocation and size constraints.
