When a comment is encountered by a compiler, the compiler simply skips that line of code. Change the program at the bottom so that it prints to the output "Hello, World! Last, we have a sentence within quotes that we'd like printed on the screen.

very nice article.

Last but not least, we will need to call the function printf to print our sentence.

The first code which will run will always reside But a program can contain thousands of lines of code and can be so complex that it is hard for us to understand.
