Overview of C Programming

Are you ready to get started coding with C? This structured introduction to the language will walk you through the fundamentals.

C is an incredibly versatile, essential language—and it's a great option for beginners who are looking to make a start in programming. It's used to build software on virtually every platform, and its list of applications is vast. C is often used to program operating systems, as well as a wide variety of embedded devices like phones, game consoles, and even spacecraft. That's why it's important to build your skills in this popular language.

The basics of C programming include: understanding data types like variables and arrays, understanding input/output operations like reading and writing data from files or other programs, controlling program flow with structures such as if-else statements and loops, memory management with pointers, understanding functions and structures—even working with libraries and modules developed by other programmers.

It may feel overwhelming at first glance—but mastering these basics will give you a strong foundation in C programming that you can use in any project.

Fundamental Concepts: Data Types & Operators

Now that you understand the core principles behind a programming language, let's dive into the fundamental concepts

When you're learning a language like C, you'll need to understand data types and operators. These are the building blocks of programming that will help you apply the language effectively.

Data types are integral in any programming language, and there are different kinds of data types in C. You'll need to learn to work with primitive data types such as integers, floats, characters, and strings. Understanding how they can be used will help you create robust programs.

Data types in C

In C programming language, data types determine the type and size of data that can be stored in a variable. Here are the data types, their storage size in bytes, and their range in C:

  1. Basic Data Types:

  • char: 1 byte (-128 to 127 or 0 to 255)

  • int: 2 bytes (-32,768 to 32,767)

  • short: 2 bytes (-32,768 to 32,767)

  • long: 4 bytes (-2,147,483,648 to 2,147,483,647)

  • float: 4 bytes (6 decimal places)

  • double: 8 bytes (15 decimal places)

  • long double: 10 bytes (19 decimal places)

  1. Derived Data Types:

  • arrays: a collection of similar data types

  • pointers: a variable that stores the memory address of another variable

  1. User Defined Data Types

  • structures: a collection of variables of different data types

  • unions: a data type that can store different types of data in the same memory location

  • enums: a data type consisting of a set of named constants called enumerators

  1. Empty Data Type

  • void : Normally used with function meaning is NULL.

It's important to note that the size and range of these data types may vary depending on the implementation and the system you are using.

OPERATORS IN C

Operators are basically special symbols that allow you to manipulate variables and values. You can use them to assign values, compare values, perform mathematical operations, and combine values. You'll need to learn how to use the different types of operators—like arithmetic operators, relational operators, logical operators, and assignment operators—to write efficient code.

These are the fundamentals of C that you'll need to understand in order to move on to more complex programming tasks. Learning these concepts will provide you with a solid foundation in the language and will give you the confidence you need to move onto more advanced features.

Here are some of the commonly used operators in Turbo C:

  1. Arithmetic Operators:

  • Addition (+): adds two operands

  • Subtraction (-): subtracts one operand from another

  • Multiplication (*): multiplies two operands

  • Division (/): divides one operand by another

  • Modulo (%): returns the remainder of division

  1. Relational Operators:

  • Equal to (==): checks if two operands are equal

  • Not equal to (!=): checks if two operands are not equal

  • Greater than (>): checks if one operand is greater than another

  • Less than (<): checks if one operand is less than another

  • Greater than or equal to (>=): checks if one operand is greater than or equal to another

  • Less than or equal to (<=): checks if one operand is less than or equal to another

  1. Logical Operators:

  • Logical AND (&&): returns true if both operands are true

  • Logical OR (||): returns true if at least one operand is true

  • Logical NOT (!): reverses the logical state of an operand

  1. Bitwise Operators:

  • Bitwise AND (&): performs bitwise AND operation on two operands

  • Bitwise OR (|): performs bitwise OR operation on two operands

  • Bitwise XOR (^): performs bitwise exclusive OR operation on two operands

  • Bitwise NOT (~): performs bitwise complement operation on an operand

  • Left shift (<<): shifts the bits of an operand to the left

  • Right shift (>>): shifts the bits of an operand to the right

  1. Assignment Operators:

  • Simple assignment (=): assigns the value of the right operand to the left operand

  • Addition assignment (+=): adds the value of the right operand to the left operand and assigns the result to the left operand

  • Subtraction assignment (-=): subtracts the value of the right operand from the left operand and assigns the result to the left operand

  • Multiplication assignment (*=): multiplies the value of the right operand by the left operand and assigns the result to the left operand

  • Division assignment (/=): divides the left operand by the right operand and assigns the result to the left operand

These are just some of the operators supported by Turbo C. There are many other operators available in the language.

So, as you get started with coding in C, remember to take the time to understand these key concepts. They are essential for writing effective programs that are not only bug-free, but also efficient and secure. Doing so will ensure that you have a strong foundation in the language that you can use for any project.

of C programming. These will come up a lot during your journey with C, so it's important to understand them as thoroughly as you can.

Understanding data types and operators is essential for any sort of programming in C; therefore, before delving deeper into this language you must have a firm grasp of these concepts. Taking some time now to study them will save you considerable effort later on.

Writing Your First C Program: Structure and Syntax

Now that you understand the basics of the C programming language, let's dive into writing your first program! While every program is a bit different, there is a general structure you should follow to make sure it runs correctly. It's all about getting the structure and syntax right.

Structure

When writing your C program, you'll want to make sure it follows this generic structure:

  1. Preprocessor directives – allow you to use libraries and declare constants.

  2. Function declarations & definitions – where you define what each function is doing.

  3. Main function – where your code actually starts running.

  4. Statements & expressions – these are the actual commands that get executed in your program.

  5. Return statement - used to return values from functions or exit programs with an exit code.

FOR EXAMPLE

#include<stdio.h> //adding some user defined function in C program

void main() //Essential function for writing C programs

{

printf("This is my first program"); //output statement used to print msg on screen

} //Program ends

Above program is used to print This is my first program

Make sure every program has these elements in this same order! That way, you'll be able to understand how your program works and avoid errors when running it.

 Introduction to Languages: The basic components of a computer are: Input unit Central Processing Unit(CPU) Output unit The CPU is further divided into three parts-   Memory unit  Control unit  Arithmetic Logic unit      Most of us have heard that the CPU is called the brain of our computer because it accepts data, provides temporary memory space to it until it is stored(saved) on the hard disk, performs logical operations on it, and hence processes(here also means converts) data into information.       We all know that a computer consists of hardware and software. Software is a set of programs that performs multiple tasks together. An operating system is also software (system software) that helps humans to interact with the computer system.      A program is a set of instructions given to a computer to perform a specific operation. or computer is a computational device that is used to process data under the control of a com...

DECISION MAKING STATEMENTS IN C

Image
  Decision Making Statements : if, if else,nested if, switch statement if STATEMENT if is most basic statement of Decision making statement. It tells to program to execute a certain part of code only if particular condition or test is true. Syntax if(<condition>)     [ Statement or block of statements]; Example #include<stdio.h> #include<conio.h> void main() { int a=9; if(a<10) { printf(“a is less than 10”); } getch(); } Output a is less than 10 Constructing the body of "if" statement is always optional, Create the body when we are having multiple statements. For a single statement, it is not required to specify the body. If the body is not specified, then automatically condition part will be terminated with next semicolon ( ; ). if -else STATEMENT It is a keyword, by using this keyword we can create a alternative block for if part. Using else is always optional i.e, it is recommended to use when we are having alternate block of condition. In any prog...
