C++ Data Types

1. Introduction

This section provides a foundational overview of arithmetic operations and their pitfalls, data types, and the importance of specifying types.

2. Numerical Data Types

short, int, long, float, double, etc. are all numerical data types in C++. In this section, you will learn about all of them as well as the pitfalls they may conceal.

3. Text Data Type

This section will guide you on char and string data types to work with text in C++. You will learn many handy string methods to make using strings easier.

Changing The String Practice

4. Other Data Types and Concepts

This section focuses on the bool data type, the use of void and auto, and covers type conversion, which is frequently used in C++.

Data Types are a classification of data items that inform the compiler or interpreter how the programmer intends to use the data. They define the operations that can be performed on the data, the meaning of the data, and the way values of that type can be stored.

Data

For computer data is just a sequence of ones and zeros. We need to tell the computer how to interpret it whether it's a number, text, symbols, or maybe even a mix of different things. And in this course you will learn how to properly do it.

Data Types

Basic data types include integer types, floating-point types, character types, and the boolean type. These types represent the most fundamental data elements, such as whole numbers, decimal numbers, characters, and true/false values.
