Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point whe…
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to c…
Question
III. Write an structure that will print a message based on the grade (A,B,C,D,or F). Do this first using an if statement. Then do it using a switch statement. The grade and message are as follows. • A . B C D • F Get some help ● Excellent Job Very Good Average Need more effort IV. For each of the following, create an if statement. Then rewrite it using the ? conditional operator. a) If x is less than z then y will be equal to x, if not y will be equal to z. b) if r is greater than or equal to x plus 2 the s will be equal to r, if not it will be equal to x-2 c) if y+5 is less than or equal to x -2 and y is less than 99 then ans will be equal to 0 if not ans will be equal to 1
