The Basics of C Programming

Console Input and Output

In C programming, console input and output are handled using
the scanf() and printf() functions.

scanf() is used to get input from the user, while printf() is used to display
output on the console.

Arithmetic Operators and Variables

C supports several arithmetic operators such as +, -, *, /, and %.

Variables are used to store data in a C program. A variable must be declared before
it can be used. The declaration specifies the type of data that the variable will
hold.

Conditional Statements

Conditional statements are used to execute different blocks of code based on
whether a certain condition is true or false.

The if, else if, and else statements are used to accomplish this in C.

Loops and Iteration

Loops are used to execute a block of code multiple times.

There are several types of loops in C, including for, while, and do-while loops.

Functions and Recursion

Functions are reusable blocks of code that perform a specific task.

In C, functions are defined using the funciton keyword.

Recursion is a technique in which a function calls itself repeatedly until a
certain condition is met.

Data Structures and File Handling

Data structures are used to organize and store data in a C program.

File handling is the process of reading from and writing to files in a C program.

In C, files are handled using the FILE and fopen() functions.
