Assignment to make a rational numbers class as follows:
create a constructor that prevents a 0 denominator in a fraction, reduces or simplifies fractions that are not in reduced form, and avoids negative denominators.
Overload the addition, subtraction, multiplication and division operators for this class.
Overload the relational and equality operators for this class. My code so far is as follows:
Build started: Project: 11.10rationalnumberclass, Configuration: Debug Win32 ------
1>main.obj : error LNK2019: unresolved external symbol "public: void __thiscall Rational::setFraction(int,int)" (?setFraction@Rational@@QAEXHH@Z) referenced in function _main
1>C:UsersJacobDocumentsVisual Studio 2010ProjectsComplexnumbers11.8projectDebug11.10rationalnumberclass.exe : fatal error LNK1120: 1 unresolved externals
part of the problem might be that I cannibalized another program dealing with complex numbers to make this. While I don't need this class to be perfect, I'm not sure I entirely understand everything about classes and overloading yet.
RAT(RAT_INT num = 0, RAT_INT den = 1){ Num = num; Den = den;
[Code].....
Two questions: 1) In the second line in main, how does C++ know to convert 2 to the appropriate RAT? 2) Is it possible to make the third line in main valid without adding global operators for all the member operators to support plain integers?
My assignment is to handle rational numbers of different denominators...
Develop rational number class that can •add •subtract •multiply •divide •reduce to simplest form Your class must be able to handle rational numbers of different denominators
This is the errors I am getting
error C4716: 'Rational::addition' : must return a value error C4716: 'Rational::multiplication' : must return a value error C4716: 'Rational::division' : must return a value error C4716: 'Rational::subtraction' : must return a value
I'm having trouble finishing this program. What I'm trying to do is create a class for Rational numbers. Get input from user for denominator and numerator. Store the numbers without a sign, and for the sign store it separately in char. I'm not supposed to use accessor functions. The part that I can't seem to know how to do is use the info that was stored in the addUp function. This function need to add two rational numbers. i need to make this function general enough that it can handle two fractions, or a fraction and a whole number, or two whole numbers. What I already have here is readin function which reads in the numerator and denominator. setnumerator and setdenominator to assign positive values. setsign should get the sign of the fraction. Finally addUp should addUp which I explained before. I have some ideas about writing the tests, but can't seem to know how to implement it to the program. The main program is still empty but all I'm supposed to do there is call the class functions.
Code: #include <iostream> using namespace std; class Rational { private: int numerator, denominator; char sign;
I cannot get my function overloading the input operator for rational type objects to work.
lab9.cpp: In function ‘std::istream& operator>>(std::istream&, const rational&)’: lab9.cpp:186:20: error: invalid initialization of reference of type ‘std::istream& {aka std::basic_istream<char>&}’ from expression of type ‘rational’ return (inputFrac);

#include <iostream> using namespace std; class rational { public: rational(); rational(int a, int b);
I tried to check the rational or irrational numbers after we take the square root. i dont get the formula. for eg. squareroot of 64 is 8 and it is rational. square root of 2 is irrational. how to check it in c++..
Is it possible to have array in class without number of elements, for example: I have a class called Plane with number of motors, and string array of passengers, but I don't have a number of passengers, but then again I have it in constructor, so can i print the list of passengers without having the number as part of the class.
Class Plane { private: int motors; //number of motors
Write a program that prompts the user to enter a number larger than 2. The program should use the Number class to determine the prime numbers between 2 and the number entered, and display them in the console window.I've been stuck for a while now and just lost in implementing classes and contstructors.
#include <iostream> using namespace std; int main(int argc, char * argv[]) { cout << "Enter a number larger than 2: " << endl; int n; cin >> n;
Say I have a class with a few member functions, and only two data members: an int* Table; and an int Size;, to store the number of elements in Table.
I'm using a copy constructor that takes in two parameters: int* table, int size. In this case, is the address that table points to the same address as the object that table is part of? And furthermore, is it possible to say table.Size? I want to compare the passed array's size to the passed size.
This code is meant to open a file and use overloaded operators for a complex number class. I am getting a lot of errors in my class declaration/definition but I am not sure why.
Can not even say this is the error as it is giving me 45 errors. l am writing code which accept employee type based on calculating the miles traveled in a year,my code is based on type of employee, number of vacation days used and no of sick days used.
#include <iostream> #include <iomanip> #include <conio.h> class employee { int emp_type; float emp_vacation;
I'm trying to make an array that takes a group of numbers and finds the largest number into a template class.
template<class TYPE> void Integers(TYPE data) { int integers[] = {4, 25, 32, 85, 150, 12, 98, 200}; int i = 0; int Max=integers[0]; for (i=1; i < 8; i++) {
[Code] ....
I'm sure I'm going about it all wrong, but I'm not sure as to get it so that it will accept the arrays input.
Create a class to store a value that represents number of hours worked and number of days worked. Must ensure that the two representations are always consistent. I have to create 2 files, I'm pretty sure: a .cpp and a .h
This is what I have so far for my .h file (I know it's NOT functional...yet):
#include <iostream> using namespace std; class NumDays { private: double hours; double days;
[Code] ...
I don't know how to start / create this .cpp file to define the variables.
I was told to use a round function to round a number to give an integer number that is closer to the real value. (for example if the number is 114.67 I need to print an int value of 115 instead of 114)
I am not exactly sure how a round function works, but I am told to include math.h library. What I try doesn't seem to work.
In this program what i'm doing is to search for a number when the vector is in order, and count how many times that number appears, the problem is that count how many times the number does not appear, but when its appear the program stays in an "standby mode" and the cursor does not move.
int buscarNumOrdenado (int x [MAX]) //MAX is the define { int num,d, LimiteInferior, LimiteSuperior,mitad; d=0; LimiteInferior = 0; LimiteSuperior = MAX-1;
So I have a template, part of a larger code, that is designed to calculate the number of multiplications it took to reach a certain number. The problem is, whenever I execute the program, mults is always printing out a strange number, perhaps its actual address.
template <class T> T power3(T x, unsigned int n, unsigned int& mults) { if (n == 0) return 1; if (n == 1) return x; if (n == 2){
I am attempting to write code that receives a number from the user and outputs the largest prime number underneath the user's number. There are no errors in my code, but no matter what number is imputed, the program says the largest prime number is 1. I cannot find where the issue is in the code. Here is the code I wrote:
I'm running a game online and designing a program to generate Enemy Stats. Basically, it's supposed to generate 25 numbers between 0 and 7(to represent 8 Attributes on a 25 Point Buy system) and count how many times each number shows up.
Here's what the code looks like:
Code: #include <iostream> #include <ctime> #include <cstdlib> using namespace std; int Generate() { int r= rand(); int s= r%7; [Code] ....
