Basics
Nim Loops
Loop Structures
Nim loops use while and for with break and continue.
Introduction to Loops in Nim
Loops are fundamental in programming, allowing you to execute a block of code repeatedly. Nim provides two primary loop constructs: while and for. In addition, you can control the flow of these loops using break and continue statements.
Using the While Loop
The while loop in Nim repeatedly executes a block of code as long as a specified condition is true. It's useful when the number of iterations is not known beforehand.
Using the For Loop
The for loop iterates over a range or collection, such as an array or sequence. It is often more concise and easier to understand than a while loop.
Controlling Loop Execution with Break
The break statement exits the loop immediately, regardless of the loop's original condition. It is useful for terminating a loop when a certain condition is met.
Skipping Iterations with Continue
The continue statement skips the rest of the current loop iteration and proceeds with the next iteration. It's handy for skipping specific conditions within a loop.
Conclusion
In Nim, loops are a powerful feature that, when combined with break and continue, provide flexible control over code execution. Understanding how to use while and for loops effectively can greatly enhance your ability to write efficient and readable code.
