The for loop is the counting loop of C++. It is usually designed to run a specific number of times, and then end. With it, it keeps a counter, to let you know where in the loop you are – useful when looping through an array which will look at soon enough. The general form…
The Do-While loop is similar to the while loop. It is a conditional loop, just like the while loop, running the body of the loop while the condition is met. However, the big difference is that the do-while loop is a post-test loop. That means that the body runs at least once, and then there…
The cin and cout commands are for reading and writing to the stream for the console. However, there are other streams, and we can set one up for reading from a file. Writing to a Text File To write to a file, you will need to create a variable used to access the file stream….
The char data type is used to store a single character. The literal value is stored within a set single quotes. Old style C strings were actually an array of chars, but now we have our own string data type. Even when we store a number in a char, it is the char value, not…
C++ provides many useful math function inside the cmath header. As with Python, in C/C++, a function is a collection of statements which can perform a task with a single call, instead of having to write them all out. We’ll look at how to create our own functions later on. Trigonometric Functions Function Description sin(radians)…
A switch statement executes statements based upon the value of a variable. It is useful to replace a series of if statements, if the if statements are all looking for an equality value. The general form of this is below: Your variable must be an integer value, and must be enclosed in parentheses. The case…
If you want to do more complex decisions in C++ there are a couple of ways to accomplish this. We’ll look at three that are fairly common. Nested If Statements Inside of an if statement true block, or the else block for that matter, you can nest another if statement. This allows you to build…
C/C++ has a couple of different ways to perform selections. We’re going to start looking at some of these. As with most languages, C./C++ has a Boolean data type, called bool. This can be used directly with your conditions, or separately to store data. Relational Operators Since we will need to compare values, C/C++ gives…
