At this point, you know exactly what variables are, the main types, and how to declare and initialize them. But you still can't do many operations with them. You need to manipulate our variables, add them, take them away, multiply, divide, and test them.
- [John] Hi, this is video Manipulating Variables.…In the previous video, we looked at C++ variables.…In this video, we are going to take a look at…C++ arithmetic and assignment operators…and getting things done with expressions.…At this point we know exactly what variables are,…the main types, and how to declare and initialize them,…but we still can't do that much with them.…We need to manipulate our variables, add them,…take them away, multiply, divide, and test them.…First we will deal with how we can manipulate them,…and later we will look at how and why we test them.…
C++ arithmetic and assignment operators.…In order to manipulate variables,…C++ has a range of arithmetic operators…and assignment operators.…Most arithmetic and assignment operators…are quite intuitive to use,…and those that aren't are quite easy to explain.…To get started, let's look at a table…of arithmetic operators followed by a table…of assignment operators that we will regularly use…throughout this course.…These are arithmetic operators,…
