Question

How many iterations will this for loop execute?

for (int Z = 10; Z>0; Z=Z-2)
a 4
b 5
c 6
d 10

Answer 1

The for loop presented will execute a total of 5 iterations, decrementing the variable Z by 2 in each iteration starting from 10 and ending when Z is no longer greater than 0.

Step-by-step explanation:

The for loop in question decrements the value of Z by 2 each time it iterates, starting from 10 and continuing until Z is no longer greater than 0. The iterations would be as follows:

• First iteration: Z = 10
• Second iteration: Z = 8
• Third iteration: Z = 6
• Fourth iteration: Z = 4
• Fifth iteration: Z = 2

After the fifth iteration, the next value of Z would be 0, at which point Z > 0 would no longer be true and the loop would terminate. Hence, the for loop will execute a total of 5 iterations.
