In this chapter, you will: Learn about repetition (looping) control structures; explore how to construct and use count-controlled, sentinel-controlled, flag-controlled, and eof-controlled repetition structures; examine break and continue statements; discover how to form and use nested control structures; | C++ Programming: From Problem Analysis to Program Design, Fourth Edition Chapter 5: Control Structures II (Repetition) C++ Programming: From Problem Analysis to Program Design, Fourth Edition Objectives In this chapter, you will: Learn about repetition (looping) control structures Explore how to construct and use count-controlled, sentinel-controlled, flag-controlled, and EOF-controlled repetition structures Examine break and continue statements Discover how to form and use nested control structures C++ Programming: From Problem Analysis to Program Design, Fourth Edition Why Is Repetition Needed? Repetition allows you to efficiently use variables Can input, add, and average multiple numbers using a limited number of variables For example, to add five numbers: Declare a variable for each number, input the numbers and add the variables together Create a loop that reads a number into a variable and adds it to a variable that contains the sum of the numbers C++ Programming: From | C++ Programming: From Problem Analysis to Program Design, Fourth Edition Chapter 5: Control Structures II (Repetition) C++ Programming: From Problem Analysis to Program Design, Fourth Edition Objectives In this chapter, you will: Learn about repetition (looping) control structures Explore how to construct and use count-controlled, sentinel-controlled, flag-controlled, and EOF-controlled repetition structures Examine break and continue statements Discover how to form and use nested control structures C++ Programming: From Problem Analysis to Program Design, Fourth Edition Why Is Repetition Needed?
