What is data type and variable?

A variable can be thought of as a memory location that can hold values of a specific type.

The value in a variable may change during the life of the program—hence the name “variable.” …

A variable that holds integers (whole numbers) has the data type Integer and is called an integer variable..

Why do we use data types?

The data type defines which operations can safely be performed to create, transform and use the variable in another computation. When a program language requires a variable to only be used in ways that respect its data type, that language is said to be strongly typed.

What type of data is money?

The money data type is an abstract data type. Money values are stored significant to two decimal places. These values are rounded to their amounts in dollars and cents or other currency units on input and output, and arithmetic operations on the money data type retain two-decimal-place precision.

What is the data type of 1?

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. Here are some examples. Notice that the float variable b got truncated.

What is range data type?

Range means the maximum and minimum value that can be stored inside the variable of a given type. For example if you have unsigned char and if we assume that the size of the datatype is 8 bits then you can store values ranging from 0 – 2^8-1 i.e. 0-255 inside it.
