Introduction to C-Programming: As seen in ENGS 20

Let’s start by defining a new data type fraction_t, designed to store the numerator and denominator of a fraction (as integers). Try implementing this below:

Now that we have our fraction type, let’s declare two variables, frac1 and frac2, of this type, and make them correspond to the fractions \(\frac{5}{3}\) and \(\frac{-2}{5}\text{.}\)

What’s the best way to go about that?

Since we are working on a fraction calculator, how would we go about adding these two fractions? Let’s store the result in a third variable, result. Can we simply say the following?

result = frac1 + frac2

Let’s try to write a function that prints a fraction.

Now let’s try our luck with a function that adds two fractions...

Now we need a function that allows the user to enter a fraction. Be sure to prevent the user from entering a denominator of zero!

Let’s multiply two fractions!

What else do we need to make our fraction calculator work?
