C/C++ :: How To Access Linked List Functions From Stack Class Without Functions
Mar 20, 2014I'm a little confused by my programming assignment this week. I've been working at it Wednesday and I've made progress but I'm still confused as to how I'm supposed to do this. The class I made is called Stack, and it's derived from a template class called StackADT. We also utilize a class called unorderedLinkedList, which is derived from a class called linkedList.
We're supposed to implement all of the virtual functions from stackADT in the Stack class. The Stack data is stored in a an unorderedLinkedList, so what I'm confused by is how to implement a few of the Stack functions because there are no functions in unorderedLinkedList which we could call to manipulate the data.
As you can see from my attached code, I'm really confused by how I'm supposed to implement the pop() and top() functions, and I also think my initializeList() function is wrong. We don't have any similar functions in unorderedLinkedList to call, so I'm at a loss of how i'd access my unorderedLinkedList. My initial thought was to call the similar functions in the class that unorderedLinkedList was derived from, linkedList, but I'm unsure of this is what we're supposed to do, or if theres actually a way to access my unorderedLinkedList without having to use the functions from the base class.
NOTE: We're not allowed to modify stackADT, unorderedLinkedList, and linkedList.
Stack.h
#include "stackADT.h"
#include "unorderedLinkedList.h"
template<class Type>
class Stack: public stackADT<Type>{
template <class T>
struct nodeType
{
T info;
nodeType<T> *link;

C/C++ :: Array Of Functions Pointing To In Class Functions With Arduino
May 3, 2013At the moment im trying out with pointing to an array of functions. I got this working as following:
typedef void (* functionPtr) ();
functionPtr functions[2][2]={{do11,do12}, {do21,do22}};
void do11(){DEBUG_PRINTLN("11");}
void do12(){DEBUG_PRINTLN("12");}
void do21(){DEBUG_PRINTLN("21");}
void do22(){DEBUG_PRINTLN("22");}
void loop(){
A=0;
B=1;
functions[A][b]();
}
But now I'm trying to use this to point to a function inside a class so instead of do11, i want to be able to point to Basic.Do11. Somehow this doesnt work and I keep on getting this message:
error: argument of type 'void (Basic::)()' does not match 'void (*)()'
C++ :: Using GNU GCC Compiler
Jun 9, 2014I am programming with the Code::Blocks IDE and using the GNU GCC compiler. When I create an simple console application that uses strings it kind of glitches out, but here's the code:
#include <iostream>
#include <cstdlib>
#include <string>
using namespace std;
int main()
ered: " << x;
[code].....
What the output is:
Please enter a string of text: Hello World
You entered: Hello
Process returned 0 (0x0) execution time : 4.735 s
Press any key to continue.
Anyway I don't know why it removes what I typed after the space I put in between Hello and World.
C :: Gcc Compiler And Pointers
Mar 3, 2013The first sample program that I am reading on the book has the following code:
Code:
* Demonstrates basic pointer use. */
#include <stdio.h>
/* Declare and initialize an int variable */
int var = 1;
}
[code]....
Is this a compiler error or is there a proper syntax for pointers using the gcc compiler?
C++ :: Class Not Seen By Compiler?
Sep 18, 2014I have an issue. VS 2013 isn't recognizing objects that I've declared when I use class functions.I'm getting this error: "Line 14 and 15: Error C2228: left of '.asciiToFpc6' must have class/struct/union"...Here's the relevant code:
Source.cpp
#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
#include "fpc6.h"
[code].....
Additionally VS apparently doesn't like my bitwise operators in my class functions and doesn't think they're doing anything. It gives "warning C4552: ['|', '<<', '>>', '&'] : operator has no effect; expected operator with side-effect" for all of them, but it seems to me the code should work fine and actually accomplish things....
C++ :: Compiler Says There Is No Constructor But It Does Have One
May 29, 2013Code:
activity = new Idle(this, NULL);
class Idle : public Activity {
private:
float mTimeInIdle;
public:
Idle() : mTimeInIdle(0) { }
Idle(Objects *actor, Goods *target) : Activity(actor, target)
{
}
Error 1 error C2514: 'Idle' : class has no constructors d:jackydocumentsvisual studio 2010projectsperfectsimperfectsimperfectsimObjectsObjects.h 43 1 PerfectSim
The activity = new Idle(this, NULL) line is located inside the Objects::Objects(...) constructor.
Would it be caused by some cyclic dependencies? How do I go about resolving it?

C++ :: Compiler Not Recognizing Numbers
Sep 8, 2013I'm working on this homework assignment where the program takes in the user's height in inches, weight in pounds, and age, then calculates their hat size, jacket size and waist size. The formulas for these are as follows:
Hat: (weight/height) x 2.9
Jacket: (height x weight)/288 then adjusted by adding 1/8 an inch for every 10 years over the age of 30 (The adjustment only takes place after a full 10 years, so there is no adjustment for 30-39, but there is for 40)
Waist: (weight/5.7) then adjusted by adding 1/10 of an inch for each 2 years over the age of 28 (the adjustment only takes place after a full 2 years, so no adjustment for 29, but there is for 30, etc)
I'm supposed to utilize functions for each of the three formulas.
There's a couple things I can't figure out.
1. Why won't the compiler recognize 2.9 and 5.7 as numbers?
2. How do I adjust the calculation for the jacket and waist based on age?
Here's what I've got so far:
#include <cstdlib>
#include <iostream>
using namespace std;
double hatSize(int weight, int height);
double jacketSize(int weight, int height, int age);
double waistSize(int weight, int height, int age);

C++ :: Check If Compiler Has 11 Enabled?
Jan 28, 2012Is there a way to check if a compiler has c++11 enabled?
I have a library and it has converters between std strings and the internal string type. I current have preprocessor surrounding the converters for u8string, u16string, and u32strings, but it requires the end user flip the switch manually. It would be nice if I could know at compile time without being told whether or not those types exist.
C++ :: When Compiler Do Template Instantiation
May 2, 2014As we know in the compilation stage, the compiler will instantiate a concrete type for a template, for example:
template<class T> void test(T m ) {
cout << m << endl;
}
int main() {
int kl = 0;
test<int>(kl);
}
In the main function, the compiler will try to have a int entry. Also we know that in the compilation stage, generally we have several steps: lexical analysis, syntax analysis, grammer analysis and intermediate language(IR).
So my question is: In which step is the instantiation done? Before IR or after IR?
C++ :: Compiler Command Line Arguments
Jun 15, 2013I have found this C++ online compiler (to use when I am at work): Compile and Execute C++ online
When you write and compile a program, on the right side (the "output" side), you can read this command line arguments:
$ g++ main.cpp -o demo -lm -pthread -lgmpxx -lreadline 2>&1
What is the meaning of the following arguments? -lm [link the math header file, right?]
-pthread
-lgmpxx
-lreadline
Any book (ebook, tutorial, printed book, whatever) where I can find all (absolutely all) these and other possible arguments?
C++ :: Compiler Error C2664 And C2228
Nov 9, 2013Working on a basic class program and I'm generating two compiler errors that I'm not sure how to fix. Header file, implementation cpp and main cpp are shown below. The specific errors are shown after the code.
Header file Code:
#include <iostream>
#include <string>
#include <cstdlib>
#include <iomanip>
using namespace std;
[Code].......
The file generates the second error, C2228, at lines 37-41 and 43. Basically where I tried using the second created object. Error message is "left of '.setFirstName' must have class/struct/union"
C++ :: Compiler Error C2370 And C2011
Nov 29, 2013Working on a solution involving inheritance. The whole solution is pretty massive at this point so I'll just focus on the problem areas. I'm getting a lot of "redefinition" and "undefined class type" compiler errors, including C2370, 2011, 2504, and 2027, in Benefit.h, Employee.h (the constant members are a big occurance) I'm also getting 2027 and 2079 in EmployeeMain.cpp. with my Benefit and Employee object calls.
Clearly I missed something in about how to code this correctly. Sadly the course textbook focuses on general OOP theory instead on the accompanying C++ syntax.

Code:
#include <iostream>
#include <string>
#include <cstdlib>
#include <iomanip>

C :: Determine Compiler Version And Which Standard It Uses?
Jul 18, 2013 Is there any code I can use to determine my compiler version and which Standard It uses? I know the following code determine that my compiler followed ANSI But how about a version of that? ****My OS is now Ubuntu
Code:
#include <stdio.h>
int main(void){
printf("File :%s
", __FILE__ );
printf("ANSI :%d
", __STDC__ ); //return 1 if it follow ANSI but version?
return 0;
}
C :: Does Compiler Only Check Qualifiers Of End Destination
May 28, 2014Code:
#include <stdio.h>
#include <stdlib.h>
const int* const ret_con()
{
typedef const int* const cip_to_c;
}
[code]....
I have two basic questions about what is happening:
1. The return value of ret_con should be pointing to const, but instead it's pointing to a (non-const) pointer to const. Does the compiler only check the qualifiers of the end destination, why doesn't this give a warning?
2. The original variable from ret_con (ci) is a local automatic, shouldn't its lifetime have expired when you leave the scope?
I also checked this with C++ compiler (taking out the auto keyword), it gave no warnings either.

C++ :: Unexpected Expression Compiler Error
Jul 30, 2013My compiler (GCC) keeps expecting an expression where it shouldn't in 1 specific piece of my code:
int zxcNewWindow( HWND parent, TCHAR *text, zxWINDOW *kid,
UINT style, int x, int y, int w, int h, int type )
// right here
{
*kid = zxDefWINDOW;
The project contains only 2 files right now and the settings are just the default for an empty Code::Blocks 12.11 project. Both files are in UTF-8 format (tried in ASCII too), I just cannot see why this is not compiling correctly. I'll post the files in the next two posts.

C++ :: Compiler Skipping User Prompts?
Mar 24, 2014the problem that I'm running into is that the compiler skips to the end when I put my initials in //User input > "Initials"
I'm using Microsoft Visual C++ 2010 Express.
Here is the assignment:
Plan and code a program to do the following. You found an exciting summer job for 5 weeks. It pays $15.50 per hour. You will input the number of hours per week that you worked and then compute your total earnings. You must pay taxes of 14%. After paying taxes, you will spend 20% of your money on cloths and 5% on school supplies. After buying clothes and supplies, you will use 25% of the remaining money for savings.
Input
Your 3 initials and the hours for each of the 5 weeks. Use the following numbers of hours for your first test 25, 30, 20, 23, 22.
Calculations
Gross pay is the rate of pay times the sum of all hours you worked. Use CONSTANTS for each of the following rates:
Tax rate 14% of the gross earnings
Clothing 20% of earnings after taxes
School supplies 5% of earnings after taxes
Savings 25% of earnings after taxes and expenses
Output:
Output your initials, total hours worked, gross earnings, taxes, net earnings after taxes, clothing expense, supplies expense, amount going to savings and amount left to spend. Output must be aligned to the right as shown with 2 decimals in all numbers. Sample output:
Initials ABC
Total Hours Worked 120.00
Gross Earnings 1860
Taxes paid 260.40
Net Earnings 1599.60
[code]....
Turn in:Be sure your output file contains user prompts and what was entered by the user. In addition to the results of your program processing. Run with above listed data.
Here is my code
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
double Initials, TotalHours, GrossEarn, TaxesPaid;
