A loop is a control structure in programming that allows you to repeat a block of code a certain number of times or until a specific condition is met. Loops are used to perform repetitive tasks, and they can help reduce the amount of code that you need to write.

There are several types of loops in programming, including:

For loop: A for loop is used to iterate over a sequence of values and execute a block of code for each value in the sequence.

While loop: A while loop is used to repeat a block of code as long as a certain condition is true.

Do-while loop: A do-while loop is similar to a while loop, but it executes the code block at least once before checking the condition.

Loops are an essential concept in programming and are used in a wide variety of applications. It’s important to understand how they work and how to use them effectively in your code.
