2 days ago · The C program structure consists of the following sections or components: Component. Description. Documentation. Comments describing the program’s purpose. Preprocessor Directives. Includes libraries and macros using #include and #define. Definition Section. Defines constants or macros used in the program.
Sep 12, 2024 · The Structure of C Program defines the arrangement of headers, the primary function, and code blocks. It starts with preprocessor commands and concludes with return lines. In this blog, we’ll understand the Structure of C Program, its different sections, why it is important, and how you can compile and execute a C Program.
There are three basic steps involved in compiling a C program: preprocessing, compilation of C source code to machine code (or assembly) (also called object code), and linking of multiple object files into a single binary executable program. Each of these steps are described below.

Whenever we create a program in C language, we can divide that program into six different sections. This section is as follows: 1. Documentation (Documentation Section) 2. Preprocessor Statements (Link Section) 3. Definition Section 4. Global Declarations Section 5. Main functions section 6. User-Defined Functions or Sub Program Section In C langua...
Programmers write comments in the Documentation section to describe the program. The compiler ignores the comments and does not print them on the screen. Comments are used only to describe that program. In the comments, programmer writes the name of the program, the author name which is making the program, and other information like – the date of t...
Within the Link Section, we declare all the Header Files that are used in our program. From the link section, we instruct the compiler to link those header files from the system libraries, which we have declared in the link section in our program. Example -: In addition to all these Header Files in the Link Section, there are a lot of Header Files ...
The definition of Symbolic Constant is defined in this section, so this section is called Definition Section. Macrosare used in this section. Example -:
Within the Global Declarations Section section, we declare such variables which we can use anywhere in our program, and that variable is called Global Variables, we can use these variables in any function. In the Global Declaration section, we also declare functions that we want to use anywhere in our program, and such functions are called Global F...
Whenever we create a program in C language, there is one main() function in that program. The main () function starts with curly brackets and also ends with curly brackets. In the main () function, we write our statements. The code we write inside the main() function consists of two parts, one Declaration Part and the other Execution Part. In the D...
