What is Structure of a C Program

C (Programming) | bartleby

The structure of a C program generally consists of several parts, including:

  1. Preprocessor directives: These are commands to the compiler to carry out certain actions before the code is compiled. For instance, they could encompass header documents, outline macros, or encompass different vital libraries.
  2. Global declarations: These are variables or capabilities which are declared at the beginning of this system and are accessible to all capabilities within the software.
  3. Main characteristic: This is the principal characteristic of this system and contains the code this is performed when this system is run.
  4. Other features: These are extra features which can be called by means of the primary function to carry out unique responsibilities.

A simple C program:

Here’s an example of a simple C program:

#include <stdio.h>

int main() {

printf(“Hello, World!”);

return 0;

}

In this case, this system includes a preprocessor directive #consist of <stdio.H>, which includes the usual input/output library. The most important feature incorporates a unmarried announcement, printf(“Hello, World!”);, which prints the string “Hello, World!” to the console. The software then returns 0, which shows that the program ran efficiently.

This is only a simple example, but C applications may be a whole lot extra complex and encompass many more features and statements. However, the primary shape remains the equal, with preprocessor directives, global declarations, the main feature, and any extra capabilities.
