COBOL uses the STRING statement to concatenate string variables. MATLAB and Octave use the syntax "[x y]" to concatenate x and y. Visual Basic and Visual Basic .NET can also use the "+" sign but at the risk of ambiguity if a string representing a number and a number are together. Microsoft Excel allows both "&" and the function "=CONCATENATE(X,Y)".
A spreadsheet's concatenate ("&") function is used to assemble a complex text string—in this example, XML code for an SVG "circle" element. In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of "snow" and "ball" is "snowball".
concatenate(string 1,string 2) returns string. Description Concatenates (joins) two strings to each other, returning the combined string. Note that some languages like C have mutable strings, so really the second string is being appended to the first string and the mutated string is returned.
This is a pictorial representation of a code concatenation, and, in particular, the Reed–Solomon code with n=q=4 and k=2 is used as the outer code and the Hadamard code with n=q and k=log q is used as the inner code. Overall, the concatenated code is a [, ]-code.
The properties of concatenative languages are the result of their compositional syntax and semantics: The reduction of any expression is the simplification of one function to another function; it is never necessary to deal with the application of functions to objects.
Primes that are the concatenation of the first n primes written in decimal. 2, 23, 2357 (OEIS: A069151) The fourth Smarandache-Wellin prime is the 355-digit concatenation of the first 128 primes that end with 719.
Hopcroft and Ullman (1979) define the quotient L 1 /L 2 of the languages L 1 and L 2 over the same alphabet as L 1 /L 2 = { s | ∃t∈L 2. st∈L 1}. [7] This is not a generalization of the above definition, since, for a string s and distinct characters a, b, Hopcroft's and Ullman's definition implies yielding {}, rather than { ε }.
Pivot tables are not created automatically. For example, in Microsoft Excel one must first select the entire data in the original table and then go to the Insert tab and select "Pivot Table" (or "Pivot Chart"). The user then has the option of either inserting the pivot table into an existing sheet or creating a new sheet to house the pivot table.
