Using of Variable
# include <stdio.h> void main() { int a = 5, b = 7; int c = a+b+3; printf (“C= %d”, c); }	# include <stdio.h> void main() { int a = 5, b = 7; printf (“SUM= %d”, a+b); }	# include <stdio.h> void main() { char a1 = ‘s’, a2 = ‘g’; printf (“%s%c%s%s”,a1,a2,a2,a1); }
O/p: C = 15	O/p: C = 15	O/p: sggs

Comments

Comments in C

Comment is the code which is not executable means compiler will not compile the comments and that’s why comments are not visible on output screen. Two types of Commenting: Type 1: double slash ‘ // ’ method the whole statement after double slash is not executed by compiler Example: try to run below code its output will be blank screen #include <stdio.h> void main(){ // printf (“Hello World!”); } #include<stdio.h> void main ( ){ //Comments // Comment printf (“Hello World!”);//abc } #include<stdio.h> //Comments void main(){ //Comments printf(“Hello World”); } o/p: blank screen O/p: Hello World! O/p: Hello World In this way you can give multiple comments anywhere in the program but double slash is used to comment only single line for commenting multiple lines use type 2. Type 2: For multiline commenting or for commenting a whole paragraph from the program we have to add /* at the start of comment and */ at the end of comment as shown in examples: #include <s

New trends and advantages of C language.

1. You can program the ROBOTS and Automatic Running Machines using C language. click here for more information. 2. For building more advanced software or Games you need to learn more advanced languages like Visual Basic, .NET, JAVA, ANDROID programming which is based on C. 3. To build a website you need only HTML and you can make your own website but for making it more advance you need to learn more web designing languages like CSS, JavaScript, Ajax, PHP and this all languages are very easy to learn if you have some basic knowledge about C. 4. After learning C you will be able to make your own software like Calculator, Games, Embedded Softwares, Compilers.

Why should I learn Computer language (Programming)? And why C language good for beginners?

1. Software is the spirit ( आत्मा ) of hardware . 2. Just by joining some hardware (Electronics Components) we can’t make our Computers, Laptops, Mobiles, Tablets, etc. so programming is essential to make this hardware functional. 3. Program instructs and controls the hardware and C is the very basic language to start. 1. By learning a computer language you'll able to build your own software, OS, Virus, Antivirus. For example, WhatsApp, Hike, Calculator, Media Player, Facebook, Twitter. 5. After learning the C language you'll be able to build your own computer applications. 6. C language Helps to learn more advanced languages like Java, Dot Net, MATLAB. because this all language depends upon C language. 7. It is good for starters because it is just like the English language and easy to understand.
