In C and C++ arrays do not support the size function, so programmers often have to declare separate variable to hold the size, and pass it to procedures as a separate parameter. Elements of a newly created array may have undefined values (as in C), or may be defined to have a specific "default" value such as 0 or a null pointer (as in Java).
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.

The format is best suited for small data chunks that don't exceed a few megabytes and can be loaded/sent into memory right away and therefore is not a streamable format. [9] The library doesn't provide compression out of the box. The format also isn't well supported in non–object-oriented languages (e.g. Fortran). [10]
Nim provides string interpolation via the strutils module. Formatted string literals inspired by Python F-string are provided via the strformat module, the strformat macro verifies that the format string is well-formed and well-typed, and then are expanded into Nim source code at compile-time.
In both languages, a string is a primitive array of characters. In Pascal a string literal of length n is compatible with the type packed array [1..n] of char. In C a string generally has the type char[n]. Pascal has no support for variable-length arrays, and so any set of routines to perform string operations is dependent on a particular ...
sizeof can be used to determine the number of elements in an array, by dividing the size of the entire array by the size of a single element. This should be used with caution; When passing an array to another function, it will "decay" to a pointer type. At this point, sizeof will return the size of the pointer, not the total size of the array.
The format string syntax and semantics is the same for all of the functions in the printf-like family. Mismatch between the format specifiers and count and type of values can cause a crash or vulnerability. The printf format string is complementary to the scanf format string, which provides formatted input (lexing a.k.a. parsing). Both format ...
