Write one c$++$ function to do all of the following. It may be either a void or value returning function. It must take two parameters, both double. You may add additional parameters if you want to$.$

If the two parameters you must use are named a and b $($you can name them what you want$),$ you must compute the following $($all results should allow fractional $($decimal$)$ values$).$

The sum of a and $b(a+b)$

The difference of a and $b(a-b)$

The product of a and $b(a^{**}(b))$

The quotient of a and $b(\frac{a}{b})$

These four values must be sent back to the calling function $($this function does not print them$).$
