Explaining Your First C Program

Here's the first C program we wrote:

#include <stdio.h> 

int main() {

  printf("Hello, World!");

  return 0;
}

Notice the following line of code:

printf("Hello, World!");

In the above code, the printf statement prints the text Hello, World! to the screen.

Remember these important things about printf:

• Everything required for the printing operation is kept inside parentheses ().
• The text to be printed is enclosed within double quotes "".
• Each printf statement ends with a semicolon ;.

Not following these rules will result in errors and your code will not run successfully.
