CompTIA ITF+ (FC0-U61) — Question 106

A global variable called `age` will be created in a program and incremented through the use of a function. Which of the following data types should be defined with the age variable?

Answer options

• A. Integer
• B. Float
• C. Double
• D. String

Correct answer: A

Explanation

The correct choice is Integer since age is typically represented as a whole number. Float and Double are not suitable because they are used for decimal values, while String is inappropriate as it represents text rather than numerical data.
