hello world program in c

```c #include

int main() {

printf("Hello, World!\n");

return 0;

}

```

Is program mein:

1. `#include `: Is line se `stdio.h` header file ko include kiya jata hai, jise standard input/output functions ke liye istemal kiya jata hai.

2. `int main() { }`: Ye program ka main function hai, jahan se program ki execution shuru hoti hai.

3. `printf("Hello, World!\n");`: `printf` function ka istemal text ko console par print karne ke liye hota hai. Yahan `"Hello, World!\n"` ko print kiya jata hai, jisme `Hello, World!` ek string hai jo double quotes ke bheetar hai. `\n` newline character ko represent karta hai, jisse "Hello, World!" ke baad ek new line par aaya jata hai.

4. `return 0;`: `main` function se `0` return kiya jata hai, jo ek convention hai ki program sahi se execute hui hai.

Is program ko compile aur run karne ke baad, aapko "Hello, World!" console par dikhega. Ye program C language mein sabse basic program hai, jise beginners usually pehle sikhate hain.
