This repository contains a simple C program that outputs the text "Hello, World!" to the console. This is often the first program beginners write when learning a new programming language, as it introduces basic concepts such as syntax, structure, and the process of compiling and executing code.
-
#include <stdio.h>
This line is a preprocessor directive that tells the compiler to include the Standard Input Output library (stdio.h
) in the program. This library contains functions for performing input and output operations, such asprintf
, which is used to print text to the console. -
int main()
Themain
function is the entry point of the program. When the program is executed, the code inside the main function is run first. Theint
beforemain
indicates that the function returns an integer value. -
{ ... }
The curly braces{
and}
define the beginning and end of themain
function's body. All the code inside these braces is what gets executed when the program runs. -
printf("Hello, World!\n");
Theprintf
function is used to output text to the console. In this case, it prints the string"Hello, World!"
followed by a newline character\n
, which moves the cursor to the next line after printing the text. The semicolon;
at the end of the line indicates the end of this statement. -
return 0;
Thereturn
statement is used to exit themain
function and return a value to the operating system. Returning0
typically indicates that the program completed successfully. This is a convention in C programming, where a return value of0
means the program executed without errors.
