Question

Which loop structure always uses a semicolon after the test condition?

A. for
B. do-while
C. while

Answer 1

do-while

Step-by-step explanation:

syntax:

do {

//the statements;

} while(the condition is true);

In the other two types of loops, you can put a semicolon after the condition, but it signifies the end of the statement (e.g. for loop, it will mean end of for statement and it's body will have no meaning)

Answer 2

I would have to go with A

Step-by-step explanation:

It could be B, but I'm going with A because of the fact that right after the condition, there is a semicolon, whereas for the do-while loop, the semicolon comes after the )

Syntax:

// For loop

for (int i = 0; i < 10; i++)

{

// Body

}

// Do-while

int i = 0;

do

{

i++;

// Other code

} while(i < 9); // We do i < 9, because by the time we get to the condition, i = 10, because the increment happens before the condition is checked
