Which data type refers to whole numbers without fractional components?

• A. Floats
• B. Booleans
• C. Integers
• D. Strings

Answer: (C)

The data type being tested is how numbers are represented when there is no fractional part. Integers are whole numbers without decimals, including zero and both positive and negative values. They’re used when you need exact counts or discrete steps, such as item counts or array indices. Floats hold numbers with fractional components like 3.14, booleans represent true/false, and strings store text. Therefore, the data type for whole numbers without fractional components is integers.
