C programming

task: Fraction sum

1. Implement the function fracsum which calculates the sum of two fractions.

2. fracsum takes four integers as its parameter.

-the first two parameters are the numerator and denominator of the first number.

-the latter two parameters are the numerator and denominator of the second number.

3. The function returns the sum of these numbers as a floating point number with double precision.

For example, if we call the fracsum function as follows:

it performs the following calculation: 

Although there are two ways to solve that fraction, in this exercise you must first calculate the value of each fraction as a floating point, and then add those floats together.
