In a programming language, an evaluation strategy is a set of rules for evaluating expressions. [1] The term is often used to refer to the more specific notion of a parameter-passing strategy [2] that defines the kind of value that is passed to the function for each parameter (the binding strategy) [3] and whether to evaluate the parameters of a function call, and if so in what order (the ...
In Pascal, arrays are a distinct type from pointers. This makes bounds checking for arrays possible from a compiler perspective. Practically all Pascal compilers support range checking as a compile option. The ability to both have arrays that change length at runtime, and be able to check them under language control, is often termed "dynamic ...
The dope vector is a complete handle for the array, and is a convenient way to pass arrays as arguments to procedures. Many useful array slicing operations (such as selecting a sub-array, swapping indices, or reversing the direction of the indices) can be performed very efficiently by manipulating the dope vector. [2]
Array's destructor deletes the data array of the original, therefore, when it deleted copy's data, because they share the same pointer, it also deleted first's data. Line (2) now accesses invalid data and writes to it. This produces a segmentation fault. If we write our own copy constructor that performs a deep copy then this problem goes away.
Provides reading and writing functionality to/from certain types of character sequences, such as external files or strings. <strstream> Provides input/output operations on array-backed streams. Deprecated in C++98, removed in C++26. <syncstream> Added in C++20. Provides std::osyncstream and other supporting classes for synchronized output streams.

stdarg.h is a header in the C standard library of the C programming language that allows functions to accept an indefinite number of arguments. [1] It provides facilities for stepping through a list of function arguments of unknown number and type.
In computer programming, a variable-length array (VLA), also called variable-sized or runtime-sized, is an array data structure whose length is determined at runtime, instead of at compile time. [1] In the language C, the VLA is said to have a variably modified data type that depends on a value (see Dependent type).
