I sew lot of sample for ASP WEB API. In althose link the post method is using
HttpResponseMessage as return tyope
Is it possible to use return type bool in WEB API post method?
I am new to c++ and trying to learn. for instance. i have a struct and method.I am trying to learn what i can do with the method if i define the return type as struct type.
struct S {
int age;
string name;
};
S method() {
//what i can do in here. with the Struct. I mean can i reach members of the struct. etc
}
I have a class where a method based on the type passed I should return a value.
prototype declared in the header file:
template <typename T>int getNum() const;
Code of the cpp file:
template <typename T> int class::getNum() const{
int c = 0;
for(int i=0;i<v.size();i++)
if(typeid(*(Pro*)v.at(i)) == typeid(T)) c++;
return c;
}
To invoke the method as I do:
ostream & operator << (ostream & os, Pro & obj) {
return os << obj.getNum();
}

How do I do a get/post for an array in c#? In C#, you get and set variables like this:
public int ID { get; set; }
How would one get and set an array in C#?
This will not work:
public uint [5] BIG_Hash {get; set;}
Is the bool keyword in C exactly like the boolean keyword in Java? why this code is getting an 'unknown type error' when I initiialze looping.
#include <stdio.h>
#include <stdlib.h>
int main()

If I am completely using the boolean concept wrong in C, should I just use break statements instead?
I try to make dll and install it under "Component Services". I tried to make method that return string but when i test it i don't get any result :
Code:
STDMETHODIMP CSimpleChat::CellMe(BSTR name, BSTR** helloMessage) {
CString temp = _T("Hi ");
temp += name;
temp += ", welcome to the simple chat server!";
BSTR str = temp.AllocSysString();
*helloMessage = &str;
return S_OK;
}
I want my method of the class to take as an input an array of data type derived from class. How can I do this?
Code:
class Planet {
public:
// typedef class Planet PlanetType;
void GetForce(int, PlanetType []);
};
Or when should I define my new data type PlanetType?
I got base class called Statistic and inherited classes from it : lsp, cpu, memory. Those methods inheriting some of methods from Statistic and implement also theirself methods. I prepared some new class called ExecuteRequest which is taking Statistic object in the constructor. What i want to achieve is after i put e.g LSP to this class i would like to determinate what specific object it is in this case LSP right? Then having that i would like to put this object to RunRequest method. How can i achieve that? See my code below:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace SOAP_testing {
public class ExecuteRequest

what is static method?

I'm new to c++ and bought the Jumping in C++ ebook. I read about the bool type but was confused about what it is and when I used it.

The error I'm getting is "Cannot implicitly convert type 'string[*,*]' to 'string'". So that tells me what the issue is. However, I'm not sure how to fix it.
How do I change this method, so that it properly returns my two dimensional array?
Code:
returnType operatorOperatorSymbol (parameterList); // syntax for operator overloading
Class Fraction
public:
Fraction operator-(const Fraction& f1){
Fraction r;
return r;
}
Is this even syntactically correct? It gives me errors. Im just trying to compile it without errors. I think the function makes sense since its returning a type Class
understand the below program.

Say I have overloaded functions with different arguments AND return types. Each set of argument has only one corresponding return type.
Code:
Vector grad(Scalar)
Tensor grad(Vector)
Later I have:
Code:
template <class T>
void test(T x) {
... Y = grad(x)
}
Then how do I automatically declare the type of Y. Do I need to make the grad function a template and specialize each of them ?
I am wondering why return type for an assignment operator cant be a void or int? Cant I write assignment operator for student class like this as we do nothing with returned value?

In my main I have a do/while loop, which is to iterate around the method calculateImportance while i is not equal to the numNodes.
do
{
int i;
int numNodes = Test.count();
for(i=0; i<=numNodes; i++)
[Code]....
I have been messing around with the data type node, hence why it is there are present, but, that doesn't seem to the answer
This is the function declaration in the header file.
node CalculateImportance();
i'm getting a new error is a wrong return type.
WebAPI.cs
namespace DarkAPP___WForm.Libs {
class WebAPI {
System.Net.WebClient wc = new System.Net.WebClient();
public WebAPI() {

i heard that it was int but later it is deprecated , so at present what is the default return type of a function ?

I want my function to return the type mpz_t, but I'm not sure how?
I've tried: mpz_t MyFunction(mpz_t A, mpz_t B){}
But it didn't work, here is my code so far, I have bolded the parts of the code which are causing errors and added the errors in the comments:
Code:
#include <iostream>
#include <mpir.h>
using namespace std;
???? A(mpz_t m, mpz_t n){
mpz_t mmo; //used to store the value of m, minus one

Is there a way around this?
I am having problems with my function definition of a function that should return a structure value.
This is the error I get compute.cpp(9): error C2146: syntax error : missing ';' before identifier 's_advertisebus'
The error is on the line where I start my function definition typing my function type as a structure. A long time ago in c the keyword struct is used with the structure type like struct s_advertisebus s_readadbus(). I tried it both ways but I got errors.
// struct.h
#ifndef STRUCT_H
#define STRUCT_H
struct s_advertisebus {

I always have confusions while using pointers with functions both as arguments and as return type.
