A loop in programming is a control structure that allows for the repeated execution of a block of code until a certain condition is met. Loops are powerful tools for automating repetitive tasks, and they help reduce the amount of code needed to perform a task multiple times. There are several types of loops, with the most common being the for
loop, the while
loop, and the do-while
loop.
Definition: A loop is a control structure that repeats a set of instructions as long as a given condition is true. Common types of loops are
for
andwhile
loops.
- A for loop is typically used when the number of iterations is known beforehand. For example, iterating through a list of items to perform a task on each item.
- A while loop repeats the code block as long as a specified condition remains true. It’s often used when the number of iterations isn’t known in advance.
- A do-while loop is similar to a
while
loop but guarantees that the block of code will be executed at least once before checking the condition.
For i from 1 to 10:
Print i
Loops are essential for a wide variety of tasks, such as processing elements in arrays, repeating operations, and creating repetitive tasks in user interfaces. They also help in optimizing performance by reducing redundancy and improving code efficiency.
