What is the data type of 1?

integer
1 is an integer, 1.0 is a floating-point number. Complex numbers are written in the form, x + yj , where x is the real part and y is the imaginary part.

Is string is a data type?

A string is generally considered a data type and is often implemented as an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding.

What type of data is age?

Age can be both nominal and ordinal data depending on the question types. I.e “How old are you” is used to collect nominal data while “Are you the firstborn or What position are you in your family” is used to collect ordinal data. Age becomes ordinal data when there’s some sort of order to it.

What are the three basic data types?

Basic types: numbers, strings, and booleans. Aggregate types: arrays and structs.

What are the two basic types of data?

What are some examples of data types?

The value types directly contain data. Some examples are int, char, and float, which stores numbers, alphabets, and floating point numbers, respectively. When you declare an int type, the system allocates memory to store the value.

What are simple data types?

Simple data types. Simple data types represent a single value. Simple data types used to create policies: The integer data type represents a positive whole number or its negative value. Examples of integers are 0, 1, 2, 3 and 4. The float data type represents a floating-point or decimal number.
