Question

Write a program that reads two fractions such as 1/2 and 1/4 and computes and stores the sum, the difference, the product and the result of dividing one by the other in four other fractions, respectively. Display the four resulting fractions. The following is a sample interaction between the user and the program: Enter two fractions: 1/2 1/4 Sum fraction: 6/8 Difference: 2/8 Product: 1/8 Quotient: 4/2 Press any key to continue. If n1/d1 and n2/d2 are the two fractions, their sum is given by: n1d2+ n2d1/d1d2 their difference is given by: n1d2-n2* d1/d1d2 Product is: n1n2/d1d2 Quotient: nl. d2/d1n2 Make sure the program pauses and waits for a key to be pressed before continuing. Put your name on top as a comment. Use comments to explain where your code may not be clear enough. After building and testing the program, submit the cpp file. There are two steps in submitting an assignment: first click Choose File and once you locate the file, click Upload to upload it. Once you have uploaded the file click Finish to submit. It will not be submitted until you click Finish. Make sure not to click Finish before uploading the files, as it will send a blank page and you can't resubmit. Each student must write his or her own program.

Answer 1

Answer:

1: #include <iostream>

2: using namespace std;

3: int main()

4: {

5: int a,b,c,d;

6: cout<<"n1: ";

7: cin>>a;

8: cout<<"d1: ";

9: cin>>b;

10: cout<<"n2: ";

11: cin>>c;

12: cout<<"d2: ";

13: cin>>d;

14: int top = (a*d)+(b*c);

15: int bottom = b*d;

16: cout<<"Sum: "<<top<<"/"<<bottom<<"\n";

17: top = (a*d)-(b*c);

18: cout<<"Difference: "<<top<<"/"<<bottom<<"\n";

19: top = a*c;

20: cout<<"Product: "<<top<<"/"<<bottom<<"\n";

21: top = a*d;

22: bottom = b*c;

23: cout<<"Quotient: "<<top<<"/"<<bottom<<"\n";

24: return 0;

25: }

Explanation:

The Program is written in C++ programming language

The Program is left numbered

Line 5 was used for variable declaration.

Variables a,b represents the numerator and denominator of the first fraction

While variables c,d represent the numerator and denominator of the second fraction

Line 6 prints "n1" without the quotes which represents the numerator of the first fraction

Line 7 accepts input for the numerator of the first fraction.

Line 8 prints "d1" without the quotes which represents the denominator of the first fraction

Line 9 accepts input for the denominator of the first fraction.

Line 10 prints "n2" without the quotes which represents the numerator of the second fraction

Line 11 accepts input for the numerator of the second fraction.

Line 12 prints "d2" without the quotes which represents the denominator of the second fraction

Line 13 accepts input for the denominator of the second fraction.

Line 14 and 15 calculate the sum of the fractions which is then printed on line 16

Line 17 calculates the difference of the fractions which is then printed on line 18

Line 19 calculates the product of the fractions which is then printed on line 20

Line 21 and 22 calculates the quotient of the fractions which is then printed on line 23
