Challenge 1: Halving a Number
In this challenge, we'll create a function which halves the value of a double.
We'll cover the following
Problem Statement
You must write the function halve()
which takes in a double
pointer and halves the value it points to.
The value should remain half outside the scope of the function as well.
*n = 10;
halve(n);
*n == 5 // The value is halved.
