The C++ if and else keywords are what enable you to make decisions. You have already seen them in action in the previous section when you detected, in each frame, whether the player had pressed the Esc key.
- [Presenter] This is the fifth video of this section,…Making Decisions with if and else;…in the previous video, we looked at random numbers;…in this video, we're going to take a look…at logical operators, and C++ if and else.…The C++ if and else keywords are what enable us…to make decisions; actually, we have already seen…if in action, in the previous section when we detected…in each frame whether the player had pressed the escape key.…
So far, we have seen how we can use arithmetic…and assignment operators to create expressions;…now we can receive some new operators.…Logical operators are going to help us make decisions…by building expressions that can be tested for a value…of either true or false; at first, this might seem…like quite a narrow choice, and insufficient…for the kind of choices that might be needed…in an advanced PC game.…Once we dig a little deeper, we will see…that we can actually make all the required decisions…we will need, with just a few logical operators;…here is a table of the most useful logical operators,…
