This online utility creates a linear or random array of integers that can be directly used in various programming languages. You can quickly switch between array syntax of over a dozen different programming languages or create a custom array format in the options. You can specify start and step values for linear arrays or range start and range end values for random arrays. Additionally, you set the desired length of the output array and can create an array of string integers. Created by math nerds from team Browserling.
With this browser-based application, you can generate an array of integers for any programming language. An array is a data structure that consists of a sequence of elements (in our case it's a sequence of integers) that are identified by an array index. Different programming languages use different syntax for creating arrays. For example, JavaScript, PHP, Swift, and Ruby use square brackets to create arrays and the elements are comma-separated, such as [1, 55, -23]. Matlab also uses square brackets, but separates the elements with spaces, for example, [1 55 -23]. Rust creates comma-separated arrays with square brackets, prefixed with a type signature [T; size], for example, [i8; 5] = [0, 3, 7, -9, 4] or [i16; 3] = [255, -146, 2]. Languages C, C#, C++, Go, Java, Visual Basic, and Mathematica put the array elements in curly brackets, for example, {1, 55, -23}. Python uses either round brackets or square brackets, depending on if you're creating tuples or lists. The Perl language, similar to Python tuples, encloses array elements in curly brackets, for example, (1, 55, -23). R uses a special syntax "c(...)" where "c" stands for a column. This language internally represents arrays as column vectors and an example of an R array is c(1, 55, -23). All in all, you can choose between eighteen programming languages and two different array types in the options. If you need a different array format for a language that's not listed, then you can create your own array syntax via the custom mode option. With this mode selected, you can specify the symbols that go before and after an array on the left and right, as well as the symbol that goes between integers. The two array types are – a linear array that lets you specify the start value, step value, and the number of integers and an array of random integers that have the range start value, range end value, and also the number of output integers. For all array types, you can also quickly quote integers to get an array of integers that are strings. Integerabulous!
In this example, we create a linear 12-element array for the Java programming language. Arrays in Java use the curly bracket format with comma-separated elements. We start the linear array at 0 and increment the subsequent elements by 2 until the array is filled with 12 integers.
This example creates a Python list with random integers in string representation. There are twenty random integers in this list from the range [-100, 100] and they're all put in quotation marks so that the elements have the string type. Just a quick reminder – Python lists, compared to tuples, which use round parentheses, can be modified but tuples are immutable and can't be modified.
In this example, we decided to create an array for our own imaginary programming language that has a unique syntax. In our language, arrays are declared via angle brackets and elements are separated using colons. We generate an array of twenty-three decreasing integers that start from the value 99 and end at -99.
You can pass options to this tool using their codes as query arguments and it will automatically compute output. To get the code of an option, just hover over its icon. Here's how to type it in your browser's address bar. Click to try!
