3 C# Operators & Conditionals

In the previous chapter, we made a bit more of a custom-made project. We learned about variables, datatypes, and the random class. We also learned about concatenation and how we can use it to get custom results. However, for now, we only got to the point where we displayed a predefined value. Even though including randomness, we just displayed a value between two set numbers. We have not yet started implementing any logic into our program.

In this third chapter, we will finally add some complexity to our algorithm. Using operators and conditional statements, we will be able to get a specifically selected result depending on our preset situations.

For our third tiny C# project, we will generate two random numbers and then compare them to determine which one is bigger. Then, we will check if the bigger one is higher than a set value and display in a Console.WriteLine() the result of both conditions.

This algorithm will use everything we learned previously, such as datatypes, the random class, concatenation, and everything we will learn during this chapter.

Let us start this chapter with a bit of theory, with the definition of an operator in C#.
