Chapter 4, Problem 1.1SRE

Fill in the blanks in each of the following statements:

All programs can be written in terms of three types of control structures:    ,    and    .   

Program Description Answer

Three types of control structures such as “sequence”, “selection” and “iteration” structures are used to write all the computer programs.

Explanation of Solution

Control structures:

• To develop any problem solving algorithm, control structures are used.
• Control structures provide the flow order in which the program statements are executed.
• There are three types of control structures:
  • Sequence structure: his structure is used to execute the program statements one by one without any alteration in the flow of execution.
  • Selection structure: This structure is used to execute the statement based on the selection or condition. This structure can alter the execution flow.
  • Iteration: This structure is used to repeat the execution of same statements for a particular number of times.
