I have written my program and it works when I keep everything in the header files, and then have my main. I am now splitting them up into implementation files, but Eclipse keeps giving me errors. It gives me error at every opening brace of the constructor and functions. It says on all of them "Redefinition of (name of constructor or method), Previously declared here." What am I doing wrong, because it works in the header file?
I wrote a simple date class and could not get it to work until I put all the code in main(). Then it worked like a charm. I have not been able to create a separate .cpp file and get it to work with my existing main().
I tried to follow [URL] which is a closed article, with no success. I tried every combination I could think of and was unable to compile without error. (Linux Mint 17,code::blocks 13.12, G++ 4.8.2). I did finally get it to work by putting *all* my code in the .h file and #including the .h file (and nothing else) in the .cpp file. This is not how it's supposed to work.
This is unbelievable! I just tried this on another computer, same OS same version of Code::Blocks and G++.
I have been working a project in C++. I have TTTMain.cpp file that has all the function calls, TTTFuntions.cpp that has all the functions, I have TTT.h file that has all the prototypes and variables and additionally I have Winner.h that has enum class Winner declaration in it. Here is my block of codes:
Winner.h file:
#ifndef winner #define winner enum class Winner {
[Code]....
My question is when I compile this gives me error on
How is it possible to store the related data of a program C++ into an external file (like as .txt) and retrieve it?
I want to write c++ program that can contain data members " id and phone"
like as Code: class profile { private: int id,phone; public: void retriever() { cout<<"Enter your ID: "; cin>>id; cout<<"Your Phone number is "<< phone; }; }
avoiding formats in above class, purpose is to store data already in txt file with different id and phone numbers and it is to be retrieved by matching id number to txt file and viewing its related phone number.
I have a small class with a static int data member. I want to zero init it. I am thinking that making a .cpp file with only one line seems too much, isn't it?
So, can I do it inside the the header file? The variable is going to enumerate how objects were created (so any alternative will do).
I am currently learning OOP, and I can't figure out what the problem is with my header file. The rest of the program complies fine though. I am using g++ on UNIX.
myClass.h:9:23: error: Rectangle.h: No such file or directory myClass.h: In function ‘int main()’: myClass.h:13: error: ‘Rectangle’ was not declared in this scope myClass.h:13: error: expected `;' before ‘rect’ myClass.h:14: error: ‘rect’ was not declared in this scope
Code: myClass.h /* This header file contains, The main function for my rectangle class program.*/
#include "Rectangle.h" using namespace std; int main(){ Rectangle rect; rect.displayMaxRectangles(); rect.process(); rect.summary();
Currently i have a system that will store user input into a txt file, and have a function that will compute the daily sales of the month(Check by system date month) and display the sales of the day and the grand total of that month.
Take for example, the system date now check that the current month is Apr. Below are my current output:
20Apr2015 $11.5 20Apr2015 $15.5 22Apr2015 $4.5 25Apr2015 $4.5 28Apr2015 $4.5 20Apr2015 $4.5 Grand Total $45
But my desired result should be as below
20Apr2015 $31.5 22Apr2015 $4.5 25Apr2015 $4.5 28Apr2015 $4.5 Grand Total $45
I am currently doing the assignment about linked list. Here are some details information about what I am doing.. This program is C++ and should run on Visual Studio 2010. And it contains three file, two datastructure header and one main cpp file.
This program is trying to arrange and show some sports records. The main program which contain the functions such as reading the result text file(each result text file contain several records of athletes), removing a file, arranging the totalresult and printing it out. And the main program is already given and I cannot overwrite it.
But when I finished and try to build the solution and run it, I am not able to run the program and it give me somethings like these...
warning C4172: returning address of local variable or temporary error C2248: 'Datastructure1::Datastructure1' : cannot access private member declared in class 'Datastructure1' see declaration of 'Datastructure1::Datastructure1' see declaration of 'Datastructure1' This diagnostic occurred in the compiler generated function 'Result::Result(const Result &)'
And I have tried to comment each function part of the header file and see if can run or not. But I still fail to do so. Here are my codes...
#ifndef DATASTRUCTURE1_H #define DATASTRUCTURE1_H class Datastructure1 { Public: Datastructure1( );
[Code] ....
There are two header files and look quite long. They are all some linked list functions . I have read and learn linked list data structure before I complete this programs. However, when I complete the functions required, the function cannot be compile....
I am a beginner with C++, taking a class right now. The lab this week is to create a user defined class and have it accesses in a separate .h header file from the main.
I think I'm finding my way through it, but I'm getting a complie error that makes no sense to me:
# include <iostream> # include <cstring> #include <iomanip> #include <cmath> using namespace std; class Course // Creating the class Course
[Code] ....
Errors: Warning1warning C4996: 'strncpy': This function or variable may be unsafe. Consider using strncpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS.
[Code] .....
I have to create an Array of type Course and then fill its member dats using various member functions. Those errors are caused by some Constructor defect, which I dont really know what it is.
I wrote a class to manage pointers better (because I am making a large program and don't want to call a constructor on somthing that was already deleted... etc...), but I am getting some compiler errors. I'm not sure what to do.
Ive been writing this code all day and these errors have been killing.
Instructions: Car Class: Write a class named Car that has the following: year. An int that holds the cars model year. make. A string object that holds the make of car. speed. An int that holds the cars current speed.
In addition, the class should have the following member functions.
Constructor. The constructor should accept the car's year and make as arguments and assign these values to a object's year and make member variables. The constructor should initialize the speed member variable to 0.
Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object's year, make, and speed member variables.
accelerate. the accelerate function should add 5 to the speed member variable each time it is called.
brake. The brake function should subtract 5 from the speed member variable each time it is called.
Demonstrate the class in a program that creates a Car object, and then calls accelerate function five times. After each call to the accelerate function, get the current speed of the car and display it. The, call the brake function five times. After each call to the brake function, get the current speed of the car and display it.
Errors: error C2061: syntax error : identifier 'stringm' error C2533: 'Car::{ctor}' : constructors not allowed a return type error C2511: 'Car::Car(int)' : overloaded member function not found in 'Car' see declaration of 'Car' fatal error C1903: unable to recover from previous error(s); stopping compilation

I have to find at least 5 errors in the following class template. I have found three and it now compiles, here is the template
#include <map> #include <utility> template <class T> class foo{ public : foo(T bar1, T bar2){ _bar1.push_back(bar1); _bar2.insert( std::pair<T,T>(bar1,bar2) );
[Code] ....
The errors I believe I have found are as follows: the vector library has not been added, the map requires two type arguments rather than one and the object which is created in main doesn't pass any values to the constructor. I fixed all of these errors and the code now compiles without errors, however the problem asks for five.
what my compiling errors mean, and what I should do to fix them: The following is my header & Implementation files. Note, the purpose of this class is a built in Array.
I changed the name of my Invoice class to 'Application' and then it generated errors such as follows

I have added my classes here, lso I have added the sln to this post.

I'm trying to make a class constructor within a namespace and I keep getting errors like: "'<variable>' is a nonstatic data member of class '<class>'" for when I try to setup parameters, and "Incomplete type is not allow" whenever I try to write out my function definition. Here's what I'm doing:
namespace test { class blah; } class blah { typedef int var[5];
[Code] .....
Also I'm unsure why there is a parameter of 'const blah &' when I mouse over blah(); (using Visual Studio 2010) within the class definition. It tells me 'blah::blah(const blah &)' and I am unsure where the parameter comes from. How can I resolve these issues?
