C (along with Python) allows juxtaposition for string literals, however, for strings stored as character arrays, the strcat function must be used. 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 ...
For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.

Python supports a wide variety of string operations. Strings in Python are immutable, so a string operation such as a substitution of characters, that in other programming languages might alter the string in place, returns a new string in Python. Performance considerations sometimes push for using special techniques in programs that modify ...
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
Slice semantics potentially differ per object; new semantics can be introduced when operator overloading the indexing operator. With Python standard lists (which are dynamic arrays), every slice is a copy. Slices of NumPy arrays, by contrast, are views onto the same underlying buffer.
real: floating-point number; can be manipulated with built-in mathematical operators; date: date and time; text: before AppleScript 2.0 (Mac OS X 10.4 and below) the text class was distinct from string and Unicode text, and the three behaved somewhat differently; in 2.0 (10.5) and later, they are all synonyms and all text is handled as UTF-16 [37]
These variables and functions have, in effect, been "sliced off". More subtly, object slicing can likewise occur when an object of a subclass type is copied to an object of the same type by the superclass's assignment operator , in which case some of the target object's member variables will retain their original values instead of getting ...
