Transcribed Image Text:54 Chapter 2 Introducing C 5. Write a program that produces the following output: Brazil, Russia, India, China India, China, Brazil, Russia Have the program use two user-defined functions in addition to main(): one named br() that prints "Brazil, Russia" once, and one named ic() that prints "India, China" once. Let main() take care of any additional printing tasks. 6. Write a program that creates an integer variable called toes. Have the program set toes to 10. Also have the program calculate what twice toes is and what toes squared is. The program should print all three values, identifying them. 7. Many studies suggest that smiling has benefits. Write a program that produces the following output: Smile! Smile! Smile! Smile! Smile! Smile! Have the program define a function that displays the string Smile! once, and have the program use the function as often as needed. 8. 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 three done!

Transcribed Image Text:printf("%d %d\n", x, y); return 0; { What is the program state after line 7? Line 8? Line 9? Programming Exercises Reading about C isn't enough. You should try writing one or two simple programs to see whether writing a program goes as smoothly as it looks in this chapter. A few suggestions follow, but you should also try to think up some problems yourself. You'll find answers to selected programming exercises on the publisher's website. 1. Write a program that uses one printf() call to print your first name and last name on one line, uses a second printf() call to print your first and last names on two separate lines, and uses a pair of printf() calls to print your first and last names on one line. The output should look like this (but using your name): Gustav Mahler First print statement ESecond print statement Gustav Mahler EStill the second print statement Gustav Mahler Third and fourth print statements 2. Write a program to print your name and address. 3. Write a program that converts your age in years to days and displays both values. At this point, don't worry about fractional years and leap years. 4. Write a program that produces the following output: For he's a jolly good fellow! For he's a jolly good fellow! For he's a jolly good fellow! Which nobody can deny! Have the program use two user-defined functions in addition to main(): one named jolly() that prints the "jolly good" message once, and one named deny() that prints the final line once.
