C/C++ :: How To Implement Pointers To Call The Function

Mar 11, 2014

write a program which contains two global variables:

1.Account number (integer)
2.Account Balance (float)

and three functions :

A function called set values which sets initial values for account number and account balance,

A function called set values which prompt user to enter the values of the above variables,

A function called input transaction which reads a character value for transaction type that is D (for deposit) and W (for withdrawal ) and a floating point value for transaction amount which updates the account balance .

Implement a pointer to call each of the functions using C++.

C :: Implement Setjmp For Function?

Feb 23, 2015

I am trying to implement setjmp for functions.

Code:

C++ :: Implement Simple Wrapper For Logging Function

Jul 22, 2014

I need to implement simple wrapper for logging function log(const char *). So the solution is below:

#include <stdio.h>
#include <sstream>
using namespace std;
void log(const char * str){ printf(str);}

[Code] ...

So, according to standard the temporary objects should not be destroyed before full expression execution (expression whitch is not a part of another expression).

The question is: is StreamLogger() << "foo1" << "foo2" << "foo3"; full expression or not?

C++ :: Singleton Base Class - How To Implement GetInstance Function

Aug 20, 2014

I'm playing with the idea of a singleton base class, but I'm having an issue with how to implement the GetInstance() function in the base class. Since I'm trying to make this ridiculously simple for the child, I'd like to handle that in the base.

class Singleton {
private:
static Singleton* instance;
Singleton() { Construct(); } // Private to avoid other instances

[Code] .....

It would be easy to use like so:

class Hello : public Singleton {
private:
std::string hello;
void Construct() { hello = "hello"; }
public:
std::string GetHello() const { return hello; }
};

Then the instance would be handled like so:
std::cout << Hello::GetInstance()->GetHello();

C++ :: Implement Member Functions Of Class Function - Failing To Get Input

Aug 17, 2013

I am supposed to implement the member functions of class Person.

class Person {
public:
Person();
Person(string pname, int page);
void get_name() const;
void get_age() const;

[Code] ....

The code I wrote is below. Where I am struggling is the program does not allow me to input age. Therefore, I cannot test if my temp for age works. It automatically defaults to 0 because it hasn't taken input. Here is my code:

// Program Title: Person function
// Program Description: The program prompts the user for first and last name and age.
// It then prints the output that was provided by the user.

#include<iostream>
#include<string>
using namespace std;
class Person {

Visual C++ :: Error C3867 Function Call Missing Argument List For Calling Thread Function

Mar 19, 2013

I searched the web for error: C3867... and the discussions where murky or obscure.

My code excerpt is:

#pragma once
#include <windows.h>
#include <stdlib.h>
#include <process.h>
void PutUpfrmIO(void *);
namespace WordParsor {

[Code] .....

I get the generic message:

error C3867: 'WordParsor::Form1::PutUpfrmIO': function call missing argument list; use '&WordParsor::Form1::PutUpfrmIO' to create a pointer to memberc:userskingc++wordparsorwordparsorForm1.h... and the suggestion fix generate another error.

One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.

C++ :: Call Of Non Function

Jan 9, 2015

I have decalred a password function which accepts an array as parameter but while compiling, it's showing an error wherever I have called it.

void password(char a[100])
{
if(::q==1) { cout<<"
Enter the master password : "; goto ENTER; }

[Code]....

Wherever I have called this function it's showing an error: "Call of nonfunction." One of the examples of the errors is below:

::q=1;
password(master_password);
//Both 'q' and 'master_password' being global variables, and master_password being array of size 25.

C++ :: No Matching Function To Call?

Sep 6, 2013

The random method in here should return a random value inside given array.

The program constantly crashes when I send the array object as full.

It will only allow for you to choose the first 4 objects in the array, if you choose object number 8, for example, the program crashes.

So Im trying to send the pointer to the array instead. But now the compiler claims not to know of any such function.

static string getRandom(string* avalible[]){
cout << "Get random";
cout << "index: " << (*avalible)->length() << endl;
int index = random((*avalible)->length()-1);
cout << "returned" + index;

[Code] .....

I can remove the "10" from the string first[10] but it doesn't make a difference.What is wrong with this?

C++ :: Function Call Is Skipping

Sep 13, 2013

When I call the member function in the main function, two functions are working fine but the third one(print()) is not. The program stops after executing the read_ages function and nothing printed on the screen. This is really strange and I could not find any problem after spending hours and had to post it here.It is a very simple program but I cant find the bug. It is a multiple file program and I am using MinGW as a compiler.

//File 1

#include<vector>
#include<string>
class Name_pairs {
private:
std::vector<std::string>names;
std::vector<double> ages;

[Code] ...

//I haven't made the sort function yet since I am stuck with the print(). Seems //like the compiler is skipping the print() function.
