The "Hello, World!" program is a classic and simple program that is often used to introduce a new programming language. The program simply prints the message "Hello, World!" to the screen. In the C programming language, the "Hello, World!" program is typically written as follows:

For Turbo C++ Compiler

If you are using Turbo C++, you need to include conio.h header file and call clrscr(); function at beginning and getch(); function at end.

#include <stdio.h>
#include <conio.h>

void main(){
    clrscr();   
    printf("Hello World");
    getch();
}

For GCC

#include <stdio.h>

void main(){
    printf("Hello World");
}

Hello World

• The first line, #include <stdio.h>, is a preprocessor directive that tells the compiler to include the contents of the standard input/output header file (stdio.h) in the program. This header file contains declarations for the standard input/output functions, such as printf().
• The int main() line defines the main function of the program. This is the entry point of the program, and the code within the curly braces ({}) will be executed when the program runs.
• The next line, printf("Hello, World!\n");, calls the printf() function to print the string "Hello, World!" to the standard output (usually the console). The \n at the end of the string is called a newline character, which causes the cursor to move to the next line after the string is printed.
• The last line, return 0;, is a return statement that tells the operating system that the program has finished executing successfully.

Learning C programming can seem daunting at first, but starting with a simple program like "Hello, World!" can help you to understand the basics of the language and build a solid foundation for more advanced programming. So, dive in and start experimenting with the language. Happy coding!
