I am stuck over these for hours. Plz help.

1.There are 3 files here: fraction.h - class definition , fraction.cpp - member functions & main.cpp- main function. How to link fraction.cpp with fraction.h? Does it need to link fraction.cpp with main.cpp also? How? Actually I tried to link them. I am not sure what I have done.

2.There are 2 errors in Fraction.cpp. It is specified in the code. It said missing ; before string .That's weird. It doesn't have any string. I can't get it. How to fix them?And I am sure every { matches with } there.How come there is unexpected file end?

3. I wrote a function- add(Fraction num) to get the numerator & denominator of (num1+num2) so that it is called in this way:

ans = num1;

ans.add(num2);

Does it have problem?

This is a simplified version of my code:

header:

Fraction.cppCode:class Fraction { public: Fraction(int numer1, int denom1); Fraction(); void display(); void add(Fraction num); private: int denom,numer; void reduce(); }

main.cppCode:#include "Fraction.h" #include <iostream> using namespace std; Fraction::Fraction(int numer1, int denom1) { numer=numer1; denom=denom1; } Fraction::Fraction() { numer=0; denom=0; } void Fraction::display() { cout<<numer<<"/"<<denom; } void Fraction::reduce() { int x; if (numer>denom) { for(x=denom;x>1;x--) { if ((numer%x==0) && (denom%x==0)) { numer=numer/x; denom=denom/x;break; }//syntax error : missing ';' before 'string' //fatal error C1004: unexpected end of file found } } if (numer<denom) { for(x=numer;x>1;x--) { if ((numer%x==0) && (denom%x==0)) { numer=numer/x; denom=denom/x;break; } } } } void add(Fraction num) { numer=numer+num.numer; denom=denom+num.denom; reduce(); }

Code:#include "fraction.h" #include <iostream> using namespace std; void main() { int numerator, denominator; Fraction num1, num2, ans; cout << "Input a fraction (a/b): "; cin >> numerator >> denominator; num1 = Fraction(numerator, denominator); cout << "Input another fraction (a/b): "; cin >> numerator >> denominator; num2 = Fraction(numerator, denominator); // addition ans = num1; ans.add(num2); num1.display(); cout << " + "; num2.display(); cout << " = "; ans.display(); cout << endl; }
