rovided below is an if statement. Which of the following select case statements can be used to replace the if statement? if grade = “A” then price = price * 2 else if grade = “B” then price = price * 1.14 else if grade = “C” then price = price * 0.9125 else if price > 50 then price = price + 5 else price = price – 4 endif endif endif endif Select one: a.select case grade case “A” price = price * 2 case “B” price = price * 1.14 case “C” price = price * 0.9125 case else if price > 50 then price = price + 5 else price = price – 4 endif endselect b. select case case “A” price = price * 2 case “B” price = price * 1.14 case “C” price = price * 0.9125 case else if price > 50 then price = price + 5 else price = price – 4 endif endselect c. select case grade case “A” price = price * 2 case “B” price = price * 1.14 case “C” price = price * 0.9125 case price > 50 then if then price = price + 5 else price = price – 4 endif endselect d. select case grade case “A” price = price * 2 case “B” price = price * 1.14 case “C” price = price * 0.9125 case price > 50 then price = price + 5 case else price = price – 4 endselect
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 where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
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 change the order of the individual statements in the software execution via search.
Provided below is an if statement. Which of the following select case statements can be used to replace the if statement?
if grade = “A” then
price = price * 2
else
if grade = “B” then
price = price * 1.14
else
if grade = “C” then
price = price * 0.9125
else
if price > 50 then
price = price + 5
else
price = price – 4
endif
endif
endif
endif
case “A”
price = price * 2
case “B”
price = price * 1.14
case “C”
price = price * 0.9125
case else
if price > 50 then
price = price + 5
else
price = price – 4
endif
endselect
case “A”
price = price * 2
case “B”
price = price * 1.14
case “C”
price = price * 0.9125
case else
if price > 50 then
price = price + 5
else
price = price – 4
endif
endselect
case “A”
price = price * 2
case “B”
price = price * 1.14
case “C”
price = price * 0.9125
case price > 50 then
if then
price = price + 5
else
price = price – 4
endif
endselect
case “A”
price = price * 2
case “B”
price = price * 1.14
case “C”
price = price * 0.9125
case price > 50 then
price = price + 5
case else
price = price – 4
endselect
