CSCI 116 Programming Project #11

You are to write a fraction calculator that doesn’t use decimal approximations to do the computation. Your program should represent the fractions as structures containing two integers, the numerator and the denominator, and should express all results as reduced fractions. Each fraction should be printed as an integer part and a proper fraction if it is greater than or equal to one, instead of as an improper fraction. Your program should read in two fractions and an operation, perform that operation, and print the result. It should then loop until the user enters zero over zero as the first fraction, and then exit. You should have separate functions to add two fractions, subtract two fractions, multiply two fractions, and divide two fractions, as well as to print a fraction. You should use the GCD function that we wrote in class to assist you in simplifying fractions.

Here is a sample output from the program:

Enter fraction calculation to perform:

1/2 + 3/4

The answer is 1 1/4

Enter fraction calculation to perform:

1/2 – 3/4

The answer is -1/4

Enter fraction calculation to perform:

1/2 * -3/4

The answer is -3/8

Enter fraction calculation to perform:

1/2 / -3/4

The answer is -2/3

Enter fraction calculation to perform:

0/0 + 1/2

Press any key to continue

You should do error checking to make sure that none of the calculations would require division by zero, and print out an appropriate error when that occurs.
