Fundamentals of Object-Oriented Programming - C++ - Data Types

This video tutorial introduces key data types in C++ such as int, float, double, char, string, boolean, and auto. It explains how to declare and initialize these variables, and how to print their values to the console. The tutorial also covers the use of the auto keyword for type inference and demonstrates the process of building and running a C++ program.

Which data type would you use to store a whole number in C++?

• float

• char

• int

• string

What is the correct way to declare a float variable with the value 10.32?

• float myFloat = '10.32';

• float myFloat = 10.32;

• float myFloat = 10.32F;

• float myFloat = "10.32";

How is a boolean value represented in C++?

• As a string

• As a character

• As 0 or 1

• As a decimal

What is the purpose of the 'auto' keyword in C++?

• To automatically print values

• To declare a variable without specifying its type

• To create a constant variable

• To define a function

What C++ statement is used to print a variable's value to the console?

• echo

• cout <<

• print()

• console.log()
