Question

Some compilers will automatically remove from loops body statements that do not need to be executed multiple times through a process known as ________.

1) classification
2) optimization
3) interpretation
4) None of the above

Answer 1

Compilers use a process called optimization to improve code efficiency by removing redundant computations within loops.

Step-by-step explanation:

The process by which some compilers remove statements from the body of loops that do not need to be executed multiple times is known as optimization. When an operation inside a loop does not change with each iteration, the compiler identifies it as an invariant and may decide to compute it once before the loop start rather than repeatedly during each iteration.
