Question

Which of the following for loop will not be an infinite loop?

Options

• for(; ;) 

• for (a = 0; a < 1; a--)

• for (a = 0; ; a++)

• for (a = −1; a < 1; a++)

Answer 1

for (a = −1; a < 1; a++)

Explanation:

for(a = -1; a < 1; a++) is not an infinite loop because a starts at -1 and increments until a < 1 becomes false.
