Documentation Section:
A documentation section consist of comment line that helps us giving the heading name or Name – what we are doing in program.
For ex: if I am writing a program for developing any software then in start-up, if I am not mentioned what I am doing, then no buddy can understand what program I am written, so for understanding we have to write a heading or tilte name like: Program for adding 2 no. For mention heading/title in c we are using comment line:
Comment Line In C Programming:
There are 2 types of comment line:
1. Single Line: (//) Ex: // Program to add 2 numbers.
2. Multiple Line: (/*……..*/) Ex: /* Write a program to add 2 numbers given by the users. */
C never compile or run the comment line. So it is not displayed on output screen. We are also using comment line for mentioning what function/ structure or work we are doing within a code.
Link Section:
It provides instruction to the compiler to link library functions from there header files. It means in c program we are using some built in programs and these programs are stored in header files. We just have to link those programs to our required filed or function.
In above line question arise what is header file:
Header file is a collection of some c built in programs.
Like For Ex: we write printf(“ABC”); and it print ABC, but you think if we want to add 2 no then we need to write a long code so for printing the value, there is also we need to write code. Yes its true but c provides us some built in (Already written programs) function, we just need to call them then it directly link with that program and run the complete code and give us output. So you can say that header file is collection of built in functions.
