Let’s take the simple example from before, and work on getting inputs from a user: In the example, we specifically set the radius, however we want to get that information from the user. With Python, we had a single command, however in C++ getting an input will consist of two steps. First we need to…
Let’s walk through the steps to create a simple C++ program that will calculate a circle’s area using the formula area = pi x r2 First we’ll set up our preprocessor directives, and an empty main function. Next we will need to define variables that will be used by the program. In C/C++ we must…
Standard convention for programming with C++ can be found in several other languages. Not only is the commands similar to other languages, but so is the structure format. Now C++ doesn’t care about white space (tabs, spaces, new line characters, etc), but it makes it easier to read and debug, and work with others. While…
C and C++ are complied languages. Unlike Python which is typically interpreted, which means the run time converts the source code to computer understandable code as it runs, C/C++ has to go through a process to make it run on a computer. This process is called compiling, but there is actually several steps to this…
A little bit of history C++ is an expansion of the C programming language. It’s main addition was the ability to create and use objects. That makes it an Object Oriented Programming (OOP) based language. You do not have to start with objects however, as it retains all of the C procedural language constructs and…
Let’s look at a simple program and work through it step by step. #include #include statements are at the top of the file, and let you include any libraries you might need. iostream, in our example is used to help process input and output. You might think this is standard, but if you are building…
