Question

1 integer ← 22 2 lowtemp ← 0 3 4 IF(integer < 10) 5 { 6 lowtemp ← lowtemp - 5 7 } 8 ELSE 9 { 10 lowtemp ← lowtemp + 10 11 } 12 13 DISPLAY(lowtemp)

What is the best description of the structure implied by line 4?

Answer 1

The structure implied by line 4 is an IF-ELSE statement used for control flow in programming. It executes different code blocks based on the evaluation of a condition, affecting the variable lowtemp in this case.

Step-by-step explanation:

The structure implied by line 4 in the student's code snippet represents an IF-ELSE statement. This is a common control flow statement in programming that allows the code to execute different blocks depending on whether a specified condition is true or false. Line 4 checks if the variable integer is less than 10.

If the condition (integer < 10) evaluates to true, the block of code from lines 5 to 7 is executed, which results in decrementing lowtemp by 5. Otherwise, if the condition is false, the block of code from lines 9 to 11 is executed, and lowtemp is incremented by 10.

Finally, line 13 displays the value of lowtemp, which has been modified based on the condition evaluated in the IF-ELSE statement.
