C++ Developer - Arithmetic Operators

This video tutorial covers the basics of variables, literals, and operators in C programming. It explains arithmetic operators like addition, subtraction, multiplication, division, and modulus, and introduces compound assignment operators for efficient coding. The tutorial also covers increment and decrement operators, providing practical examples and a challenge exercise to reinforce learning.

What is the primary purpose of operators in C programming?

• To write comments

• To create variables

• To perform operations on data

• To store data

Which symbol is used for the modulus operator in C?

• *

• +

• %

• -

What is the result of the integer division 10 / 3 in C?

• 4

• 3

• 3.33

• 3.0

What does the modulus operator (%) return?

• The remainder of a division

• The quotient of a division

• The sum of two numbers

• The product of two numbers

What is the purpose of compound assignment operators?

• To simplify arithmetic operations

• To create new variables

• To write comments

• To store data

Which of the following is a compound addition assignment operator?

• -=

• *=

• +=

• /=

What does the increment operator (++) do to a variable?

• Increases its value by one

• Divides its value by two

• Decreases its value by one

• Multiplies its value by two

How can you decrease a variable's value by one using a shorthand operator?

• ++

• -=

• +=

• --

What is the equivalent of 'myInt++' in long form?

• myInt = myInt + 2

• myInt = myInt - 1

• myInt = myInt + 1

• myInt = myInt * 1

What is the main advantage of using increment and decrement operators?

• They reduce memory usage

• They allow for faster execution

• They make code more readable

• They simplify common operations
