Adding Fractions..help with the output

[jhotz30]

I am having a minor problem getting the correct output on the following program. I am sure it is just a simple quick fix but I can't figure it out..any help would be greatly appreciated.

Desired Output:
Enter n1:1
Enter d1:2
Enter n2:1
Enter d2:2
1/2 + 1/2 = 1 0/4
PROGRAM ENDS

Here is the output I am getting with my program:

Enter n1:1
Enter d1:2
Enter n2:1
Enter d2:2
1/2 + 1/2 = 1
PROGRAM ENDS

Here is my program...again, any help is greatly appreciated

13 {
14 int a, b, c, d, e;
15
16 cout<<"Enter n1:";
17 cin>>a;

19 cout<<"Enter d1:";
20 cin>>b;
21
22 cout<<"Enter n2:";
23 cin>>c;
24
25 cout<<"Enter d2:";
26 cin>>d;
27
28 a/b + c/d;
29 e = (a*d + b*c)/(b*d);
30
31 cout<< a << "/" << b << " + " << c << "/" << d << " = " <<e<<endl;
32 cout<<"PROGRAM ENDS"<<endl;

Funny requirement, but anyway, is below what you want?

int f;

e = a*d + b*c;
f = b*d;

cout<< a << "/" << b << " + " << c << "/" << d << " = ";
cout << e/f << " " << e%f << "/" << f << endl;

No. The answer is actually 1 0/4

Another example would be:

Enter n1:3
Enter d1:4
Enter n2:5
Enter d2:8
3/4 + 5/8 = 1 12/32
PROGRAM ENDS

I can't figure it out. Thanks for trying!

Does this work?

whole = (a*d+b*c)/(b*d);
numer = (a*d+b*c)%(b*d);
denom = b*d;

EDIT: I realized that Eric Dus solution gives the same result. His solution should work fine.

How do you know the following code doesn't work, have you tested it? What result you got from it?

cout<< a << "/" << b << " + " << c << "/" << d << " = ";
cout << e/f << " " << e%f << "/" << f << endl;

to jhotz30:
Why isn't 3/4 + 5/8 = 1 3/8 instead of 1 12/32?

[jhotz30]

to fun2code...I am not looking for the answer 104...I need it to read 1 "space" 0/4

to bufbill:
I have no clue why. we have to match our instructers code. another example would be....

Enter n1:2
Enter d1:8
Enter n2:1
Enter d2:3
2/8 + 1/3 = 0 14/24
PROGRAM ENDS

PLease help!

Thanks

You've got the digits you need, just add the space and slash as characters. that part is easy (and done above by EricDu).

AWESOME...yes it worked. Thanks everyone for the help!
