Rust: Control Flow, Making Decisions with If, Else, and Loops
Programs are not just top-to-bottom lists of instructions. For software to be useful, it needs to react to data, make decisions, and repeat tasks. A game needs to keep running until the player quits. A server needs to respond differently to an admin than to a guest. The mechanisms that guide a program through these decisions are called Control Flow. Let’s go over how Rust handles branching logic (if/else) and repetition (loops). We will also build a classic beginner project: a number-guessing game that utilizes an infinite loop and conditional breaking. ...
