Here is a simple "Hello, World!" program in C:

#include <stdio.h>

int main(void)
{
printf("Hello, World!\n");
return 0;
}


This program includes the stdio.h header file, which contains declarations for functions such as printf(). The main() function is the entry point of the program and is where the code execution starts. The printf() function is used to print a string to the standard output (in this case, the console). The \n at the end of the string indicates a newline character, which causes the string to be printed on a new line. The return 0; statement at the end of the function indicates that the program has completed successfully.

To compile and run this program, you can use a C compiler such as gcc. For example, you can save the above code to a file called hello.c, and then compile and run it like this:

$ gcc hello.c -o hello
$ ./hello
Hello, World!
