Question

Given the following while loop, what is the value assigned to variable z for the given values of variables a, b and c?

mult = 0;

while (a < 10) { mult = b * a; if (mult > c) {

break;

}

a = a + 1;

}

z = a;

a = 4, b = 5, c = 20

Answer 1

Answer

a, b, c = 4, 5, 20
mult = 0;
while (a < 10) {
    mult = b * a;
    if (mult > c) {
        break;
    }
    a = a + 1;
}
z = a;

iteration 1:
-------------
mult = 5*4 = 20
mult > c => 20 > 20 is false. so, loop will not break
a = a+1 = 4+1 = 5

iteration 2:
-------------
mult = 5*5 = 25
mult > c => 25 > 20 is true. so, the loop will break.

so, final value of a after the loop ends is 5. hence the variable z is set a value of 5.
