You've now learned about the two fundamental pillars of control flow: conditionals (if) and loops (loop, while, for). The real power comes when you start combining these two concepts to build more complex and interesting logic. In this article, we'll explore some common patterns for using if expressions inside loops.
In the previous article, we learned the basics of if-else expressions. This is great for handling a single condition, but what if you have multiple conditions you want to check? For this, Rust provides the else if expression.
Welcome to our fourth series! Now that you've built some complete console applications, it's time to dive deeper into one of the most fundamental concepts in programming: control flow. Control flow allows you to run different blocks of code based on certain conditions. The most common way to do this is with if expressions.
In the previous articles, we explored how if-else expressions can be used to control the flow of our program. Now, we're going to look at a particularly powerful feature of Rust: because if is an expression, we can use it on the right side of a let statement to conditionally assign a value to a variable.
