2) Steps to write C programs and get the output

3) Creation, Compilation, and Execution of a C program

4) The basic structure of a C program

 This is the main function from where the execution of any C program begins.

3) {

 This indicates the beginning of the main function.

4) /*some comments */

 Whatever is given inside the command in any C program won't be considered for compilation and execution.

The explanation for the above C basis Program:

Let's see the section of the above simple C program line by line.

Steps to write C programs and get the output:

Below are the steps to be followed for any C program to create and get the output. This is common to all C program and there is no Exception whether its a very small C program or very large C program.

1) Create a program

2) Compile the program

3) Execute or Run the program

4) Get the output.

Creation, Compilation and execution of a C program:

Prerequisite:

  • If you want to create, compile and execute C programs on your own, you have to install a C compiler in your machine. Then, you can start to execute your own C programs in your machine.

  • You have to install a C compiler and compile and execute C programs in your machine.

  • Once C compiler is installed in your machine, you can create, compile and execute C programs.
