Basic Output

In C there is a function called printf that sends output to the terminal. For example, the statement:

      printf("Hi there!\n");

prints the message ``Hi there!''-without the quotes--on the terminal. Notice that the message string is contained in double quotes. You might be wondering what the characters ``\n'' are doing in the message string above.
