Of the following, which is NOT a logical error?

A logical error means the program runs, but it gives wrong output because the logic is incorrect.

Now check each option.

Option (a):

Using $'='$ instead of $'===' $ for comparison is a logical error.

Because $'='$ is used for assignment, while $'===' $ is used for strict comparison.

So, this may give wrong result.

Option (b):

Divide by zero is generally considered a run-time error.

The program may stop during execution.

Option (c):

Failing to initialize counter and total variables before loop execution is a logical error.

Because the program may use garbage or incorrect values and produce wrong output.

Option (d):

Using commas instead of required semicolons in a for loop header is a syntax error.

The program will not compile or run properly.

Since the question asks which is NOT a logical error, the best answer is syntax error.
