 Control structures are statements that modify the running state of your program - that is, they turn your program into a **state machine** and allows it to perform logical decisions. Your program can be in a different state depending on various conditions. For instance, **if** you're hungry **then** you are empty, but if you eat, you are full. **Or** if you're **not** hungry or empty, then you are something else that is not defined. Notice how the state can change depending on the conditions that are set. We call these **conditionals** and they impart intelligent logic into our programs. Control structures are statements that modify the running state of your program - that is, they turn your program into a **state machine** and allows it to perform logical decisions.
