Let’s get a bit more practical!
Often in our examples, we simplify variable names to match their data type (myInt or myNum for int types, myChar for char types, and so on). This is done to avoid confusion.
However, for a practical example of using variables, we have created a program that stores different data about a college student: Continue reading C++ Variables Examples
Variables are containers for storing data values.
In C++, there are different types of variables (defined with different keywords), for example:
int – stores integers (whole numbers), without decimals, such as 123 or -123double – stores floating point numbers, with decimals, such as 19.99 or -19.99char – stores single characters, such as ‘a’ or ‘B’. Char values are surrounded by single quotesstring – stores text, such as “Hello World”. String values are surrounded by double quotesbool – stores values with two states: true or falseOften in our examples, we simplify variable names to match their data type (myInt or myNum for int types, myChar for char types, and so on).
