Question

What is another way of declaring this for loop:

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

A) for (int x = 10; x > 0; x--)
B) for (int x = 1; x <= 10; x++)
C) for (int x = 0; x <= 9; x++)
D) for (int x = 9; x >= 0; x--)

Answer 1

The correct way to declare another version of the for loop 'for (int x = 0; x<10; x++)' that loops with the same range and iteration count is Option C: for (int x = 0; x <= 9; x++).

Step-by-step explanation:

An alternative way of declaring the for loop for (int x = 0; x<10; x++) would be to use a different starting point, end condition, or increment/decrement operation while ensuring that the loop executes the same number of times and in the same manner. Among the options provided:

• Option A changes both the starting point and uses a decrement operation, which reverses the count direction.
• Option B increases the starting value to 1 and runs until x is less than or equal to 10, which does not follow the initial range exactly.
• Option C starts at 0 and continues as long as x is less than or equal to 9, incrementing x by 1 for each iteration, which is effectively the same range as the original loop.
• Option D also reverses the loop, counting downwards from 9.

Therefore, the correct answer is Option C: for (int x = 0; x <= 9; x++), which is the correct way to declare the loop with the same iteration behavior as the original loop statement.
