How do loops differ from selection structures?

Loops and selection structures serve different purposes in programming. Loops repeatedly execute a block of code as long as a specified condition is true, allowing for repetitive tasks. In contrast, selection structures, such as if-else statements, execute a block of code based on whether a condition evaluates to true or false, providing a way to make decisions in the flow of the program. Essentially, loops focus on repetition, while selection structures focus on decision-making.
