/* 
 * In C, one function can call another. Write a program that calls a function 
 * named one_three(). This function should display the word one on one line, 
 * call a second function named two(), and then display the word three on one 
 * line. The function two() should display the word two on one line. The main()
 * function should display the phrase starting now: before calling one_three() 
 * and display done! after calling it. Thus, the output should look like the 
 * following:
 *
 * starting now:
 * one
 * two
 * three
 * done!
