Understanding Data Types in Programming

Data Types in Programming

Data types describe the kinds of values that a variable can store. They establish the kind of operations that can be carried out on the data, the amount of memory needed to hold the data, and the possible range of values. Integer, float, double, char, and boolean are a few examples of common data types. A boolean data type stores either true or false values, while a float or double data type stores floating point numbers, a char data type stores single characters, a string data type stores a series of characters, and an integer data type stores full integers. The type of data to be saved and the unique program requirements both influence the data type to be used.

Values of Variables

Suppose that x is an int variable, ch is a char variable, and the input is:
276.
Choose the values after the following statement executes:
cin >> ch >> x;
The values for the data types variables after the following statement executes are:
ch = '2', x = 76

What is a Data Type?

A data type is a classification of data that specifies which type of value a variable can hold. It also determines the operations that can be performed on the data. Data types in programming are used to ensure that the correct type of data is stored in memory and manipulated as intended by the program.
