C Tokens, Keywords, Identifiers, Constants, Variables, Data Types In this tutorial, you will learn What is a Character set? Token Keywords and Identifiers What is a Variable? Integer data type Floating point data type Constants What is a Character set? Like every other language 'C' also has its own character set. A program is a set of instructions that when executed, generate an output. The data that is processed by a program consists of various characters and symbols. The output generated is also a combination of characters and symbols. A character set in 'C' is divided into, Letters Numbers Special characters White spaces (blank spaces) A compiler always ignores the use ofcharacters, but it is widely used for formatting the data. Following is the character set in 'C' programming: Letters Uppercase characters (A-Z) Lowercase characters (a-z) Numbers All the digits from 0 to 9 White spaces Blank sp

How to write Comments in C Programming What Is Comment In C Language? A comment is an explanation or description of the source code of the program. It helps a developer explain logic of the code and improves program readability. At run-time, a comment is ignored by the compiler. There are two types of comments in C: 1) A comment that starts with a slash asterisk /* and finishes with an asterisk slash */ and you can place it anywhere in your code, on the same line or several lines. 2) Single-line Comments which uses a double slash // dedicated to comment single lines Example Single Line Comment // single line comment example Here is an example of comments type // C program to demo // Single Line comment #include <stdio.h> int main(void) { // This is a single line comment printf("Guru99"); return 0; // return zero } Example Multi Line Comment /* Sample Multiline Comment Line 1 Line 2 …. … */ Example Multi Line Comment #

First C Program

Your First C Program Here, is a Hello World program in C #include<stdio.h> //Pre-processor directive void main() //main function declaration { printf("Hello World"); //to output the string on a display getch (); //terminating function } Here is the code explanation: Pre-processor directive #include is a pre-processor directive in 'C.' #include <stdio.h> , stdio is the library where the function printf is defined . printf is used for generating output. Before using this function, we have to first include the required file, also known as a header file (.h). You can also create your own functions, group them in header files and declare them at the top of the program to use them. To include a file in a program, use pre-processor directive #include <file-name>.h File-name is the name of a file in which the functions are stored. Pre-processor directives are always placed at the beginning of the program. The main function The

What is C Programming Language? Basics, Introduction and History What is C programming? C is a general-purpose programming language that is extremely popular, simple and flexible. It is machine-independent, structured programming language which is used extensively in various applications. C was the basics language to write everything from operating systems (Windows and many others) to complex programs like the Oracle database, Git, Python interpreter and more. It is said that 'C' is a god's programming language. One can say, C is a base for the programming. If you know 'C,' you can easily grasp the knowledge of the other programming languages that uses the concept of 'C' It is essential to have a background in computer memory mechanisms because it is an important aspect when dealing with the C programming language. IEEE-the best 10 top programming language in 2018

Operator in C Programming Language

An operator is a symbol which operates on a value or a variable. For example: + is an operator to perform addition. C has wide range of operators to perform various operations. C Arithmetic Operators An arithmetic operator performs mathematical operations such as addition, subtraction and multiplication on numerical values (constants and variables). Operator Meaning of Operator + addition or unary plus - subtraction or unary minus * multiplication / division % remainder after division( modulo division) Example 1: Arithmetic Operators // C Program to demonstrate the working of arithmetic operators #include <stdio.h> int main () { int a = 9 , b = 4 , c ; c = a + b ; printf ( "a+b = %d \n" , c ); c = a - b ; printf ( "a-b = %d \n" , c ); c = a * b ; printf ( "a*b = %d \n" , c ); c = a / b ;
