Structure of c language

Structure of c

The structure of c program is nothing but the way of framing the group of statement while writing a c program. Step to learn c language. we have arrived to a conclusion that a program us a collection of statement.

1. Documentation Section-

This section is used to declaration of the program name or comments.

2. Pre-processor Directives-

This section is used to start with # symbol. These statement instruct the compiler to include the specified file in the begenning of the program.
E.G-     "#include "

3. Global Declaration-

The variable that are declaration all the function are called Global variable. All the function can access these variable by default the global variable initialised with zero.

4. Main() -

Each and every c programs should have a function main() and this function is always executed first. The statement is closed with in left and right curly braces "{ }" are called body of function.

5. Declaration Section-

The local variable that are to be used in the main() should declaration in this section.

6. Executable Section-

This section contain the builting block of the program. The block containing executable statement represent the direction given to the processor to perform the task.

7. User Defined Function-

This is last optical selection of the program structure. The function write by the user to perform particular task are called user Defined function.

                 void main()
                 {

             printf("This is C programming Tutorial");
             getch();
