Mar 16, 2014 · #define MAX_ITEMS 100 const char pArray[MAX_ITEMS] It should be noted that the second option is wasteful. Because you can not dynamically resize this array you must allocate a large enough chunk to hold the maximum number of items your program could create. Finally, you can always use data structures provide by C++. std::vector is such a class.
Apr 12, 2012 · I want to be able to 'build' a numpy array on the fly, I do not know the size of this array in advance. For example I want to do something like this: a= np.array() for x in y: a.append(x) W...
Mar 7, 2015 · Pratically it means "don't use the value returned. The implementation, you use, have chosen to make a concrete value named the unspecified value. It is printed #<unspecified>. Rather than removing the unspecified value from the list, I recommend you figure out where the value come from in the first place.
Nov 22, 2021 · 3.4.4 1 unspecified behavior use of an unspecified value, or other behavior where this International Standard provides two or more possibilities and imposes no further requirements on which is chosen in any instance. 2 EXAMPLE An example of unspecified behavior is the order in which the arguments to a function are evaluated.
My question is how to define unspecified constants in Coq. To make clear what I mean, assume the following toy system: I want to define a function f:nat->nat, which has the value 0 at all but one place w, where it has the value 1. The place w shall be a parameter of the system. All proofs of the system can assume that w is fixed but arbitrary.
I know it could be done using malloc, but I do not know how to use it yet.. For example, I wanted the user to input several numbers using an infinite loop with a sentinel to put a stop into it (i.e. -1), but since I do not know yet how many he/she will input, I have to declare an array with no initial size, but I'm also aware that it won't work like this int arr[]; at compile time since it has to have a definite number of elements.
Feb 27, 2014 · An array type with unspecified size is incomplete. 8.3.4/1: If the constant expression is omitted, the type of the identifier of D is “derived-declarator-type-list array of unknown bound of T”, an incomplete object type.
Jul 22, 2015 · (define <variable> <unspecified>) where <unspecified> is a side-effect-free expression returning an unspecified value. Consider (define foo) (define bar) It is up to the implementor whether the same unspecified value that is bound to both foo and bar. Try this program: (define unspecified) (define unspecified1) (eq? unspecified unspecified1)
Mar 3, 2017 · How can I define unknown functions that have certain algebraic properties? Example: I want to define the conjugation operator with the properties: bar(a+b) = bar(a) + bar(b) and bar(a*b) = bar(a)*bar(b). The goal is that maple should then use these properties to simplify a polynomial expression involving bars.
Jun 1, 2021 · As mentioned in many other answers, a function taking an unspecified number of arguments of unspecified type just means it's caller doesn't know about its definition. It's completely different from variadic functions where you must define with ... and then use va_list in stdarg.h to obtain the arguments
