Fundamentals of Object-Oriented Programming - C++ - Constants

The video tutorial explains data types in C++, focusing on integers and floating point variables. It demonstrates how to calculate the area of a circle using float variables, including user input for the radius and outputting the result. The tutorial covers declaring constants, using the extraction operator, and performing arithmetic operations in C++.

Which of the following is NOT a type of floating point variable in C++?

• float

• double

• long double

• integer

What is the convention for naming constant variables in C++?

• Using all caps

• Using lowercase letters

• Using camelCase

• Using underscores

What value is assigned to π in the program?

• 3.14159265

• 3.14159F

• 3.14159

• 3.14

How is the area of the circle calculated in the program?

• π times radius

• π times radius squared

• radius squared

• π times diameter

What is the output of the program when the radius is 8.11?

• 205.629

• 208.629

• 206.629

• 207.629
