Can I passed a function directly as an argument / parameter to another function like the example below: function calculateSomething (getRandomNumber()) { // Do some calculation and return it } Without specifying the parameter name, can this be done? 1 Answer Michael Liendo 15,326 Points...
the next example shows how several different functions are passed into a function namedsum(). As you can see from the definition of the sum function, its first argument is a function which it namesf, and that function takes one Int as a parameter, and returns anIntas a function result: ...
I want to pass a function name (Y) as a procedure parameter. Can someone tell me how to do this? My current solution was OK (just) for a couple of forms but unwieldy and non-expandable for even 4 forms. I suspect the answer is something to do with addresses and pointers but I hav...
Bobbie, To pass a procedure as a parameter you need to define a type for the procedure eg ... TYPE IFunction = Function (X : Integer) : Integer; VAR IFun : IFunction; FUNCTION Int_Fun (Y : Integer) : Integer; VAR I, J : Integer; BEGIN I := 1; For J := 2 To Y Do I ...
ref=appI don't know how it's working, since the function add() doesn't accepts any parameter, yet, it receives the add() function as an argument and calculates the sum twicehttps://code.sololearn.com/cMZdR8U68haX/?ref=app functionsfunction-argumentsc...
Of course, parameter Fn must be specialized as, say, template<typename H> function<int(void)> FnInt = H::GetInt; For GetDbl I will have vector<double> vRes, and push_back(H0::GetDbl()) and template <typename H> function<double(void)> FnDbl = H::GetDbl;...

The key property of thenameparameter that makes this technique work is thatnamehas to be copied. Indeed, the essence of this technique is totry to make the copy operation happen on the function call boundary, where it can be elided,rather than in the interior of the function. This need ...
Therefore, when we use a std::array as a function parameter, we have to explicitly specify both the element type and array length: #include <array> #include <iostream> void passByRef(const std::array<int, 5>& arr) // we must explicitly specify <int, 5> here { std::cout << arr[...
