Some integer examples include:Ĭharacters are letters or other figures that programmers might combine in a string. Integers are digits that account for whole numbers only. Here are some examples of the data types listed above that you might encounter when programming: Integer Data type examplesĭata types can vary based on size, length and use depending on the coding language. Programmers might use or encounter the void data type in early system testing when there are no responses programmed yet for future steps.

Void data types tell a user that the code can't return a response. Similar to the nothing type, the void type contains a value that the code cannot process. It's also called the "nullable type." 10. This might indicate that a code is missing, the programmer started the code incorrectly or that there were values that defy the intended logic. The nothing data type shows that a code has no value. When this happens, the Boolean data directs the program's response, which determines the next code in the sequence. These can be responses to "if/when" scenarios, where code indicates if a user performs a certain action. It's typically one of two values-true or false-intended to clarify conditional statements. Booleanīoolean data is what programmers use to show logic in code. Strings can include both upper and lowercase letters, numbers and punctuation. This often incorporates a sequence of character data types that result in specific commands depending on the programming language. StringĪ string data type is a combination of characters that can be either constant or variable. Sometimes a short data type is a single integer. Programmers represent these as whole numbers, and they can be positive or negative. Similar to the long data type, a short is a variable integer. Programmers use an ampersand to indicate the data type is a long variable. Sometimes, these can represent integers with 20 digits in either direction, positive or negative. Long data types are often 32- or 64-bit integers in code. There are two main floating-point data types, which vary depending on the number of allowable values in the string:įloat: A data type that typically allows up to seven points after a decimal.ĭouble: A data type that allows up to 15 points after a decimal. Floating point (real)įloating-point data types represent fractional numbers in programming. Since these are typically integer values, some programs can store basic mathematical operations like days elapsed since certain events or days away from an upcoming event. Dates are typically a combination of integers or numerical figures. This data type stores a calendar date with other programming information. Characters are usually fixed-length figures that default to 1 octet-an 8-bit unit of digital information-but can increase to 65,000 octets. Programmers might represent these data types as (CHAR) or (VARGCHAR), and they can be single characters or a string of letters. In coding, alphabet letters denote characters. The number of digits can vary based on the device, and some programming languages may allow negative values. An integer's value moves from one integer to another without acknowledging fractional numbers in between. Integer data types often represent whole numbers in programming. Related: What Is Java? (With FAQs) 10 data typesĮach programming language uses a different combination of data types. Most programming languages including C++ and Java use the same basic data types. You can also think of them as categorizations that different coding programs might combine in order to execute certain functions.

In this article, we define common data types in programming and provide examples of each. Learning about the basic types of data for coding can help you better understand these processes. These data types can determine how much memory a computer needs to process the code, how long it might take to load certain features and what functions a program might perform.
