Solution for Exercise 4-2
ex0402
#include <stdio.h> int main() { puts("I love displaying text!"); return(0); }
Notes
* A long time ago, when computers were controlled primarily by the command prompt, I wrote a program like this. It displayed the text "Who's there?" The name of the program was Knock-Knock
.
* Incidentally, you don't need to save updates as separate projects. If the book asks you to change a project, such as "modify ex0401 to ex0402," you can simply keep working on the original project. That's easier.
