Hello, World!
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.
Code Explanation
#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()The
mainfunction is the entry point of the program. When the program is executed, the code inside the main function is run first. Theintbeforemainindicates that the function returns an integer value.
{ ... }The curly braces
{and}define the beginning and end of themainfunction’s body. All the code inside these braces is what gets executed when the program runs.
printf("Hello, World!\n");The
printffunction 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;The
returnstatement is used to exit themainfunction and return a value to the operating system. Returning0typically indicates that the program completed successfully. This is a convention in C programming, where a return value of0means the program executed without errors.
