Every programming language has its own structure in which the program code should be written. In this lesson, we are discussing the structure of C programs.
Let’s consider the simple C program given below:
main()
{
/*Example Program*/
printf("Welcome to CSAdeeb.com");
}
The output of the above program should be as shown below:
Welcome to TECHAntena
The first line of the program code contains a function main().
The main() is required by every C program. The execution of a C program starts from the main function.
The second line has an opening brace { which is used to indicate the beginning of the function main().
The third line of the program code contains /* and */ which is used to provide additional information on the program code to the programmer. Anything between /* and */ will not be executed by the compiler and is called Comments.
The fourth line contains the instruction to print “Welcome to CSAdeeb.com”. The printf() is a function used to print things in the C programming. This line of code is to be called a statement.
The last line of the code contains an ending brace { which indicate the ending of the function body.
