2.1 Write a new float function called lookup for your interp.cpp file that takes two float arrays and a float number as arguments. The first array will contain x; and the second will contain the corresponding y; values. The float number given is the r value for which an 1 interpolated y is needed. You will need to write code to locate the index, i, such that r; < x < Ti+1· Keep your code general, without making any assumptions about the values, ri, other than that they are increasing order. Remember to do something appropriate if r has a bad value. You may find that just 3 arguments to the function lookup is not enough to do this. You probably want to test your function with some prints at this stage just to make sure the index chosen is correct (but don't leave those prints in the final version). 2.2 If you can assume that the r; values are uniformly spaced and you know the spacing, is there a fast and simple way to find the right index? Note: Don't change your code.

2.1 Write a new float function called lookup for your interp.cpp file that takes two float arrays and a float number as arguments. The first array will contain r; and the second will contain the corresponding y; values. The float number given is the x value for which an 1 interpolated y is needed. You will need to write code to locate the index, i, such that x; < I < Li+1. Keep your code general, without making any assumptions about the values, ri, other than that they are increasing order. Remember to do something appropriate if r has a bad value. You may find that just 3 arguments to the function lookup is not enough to do this. You probably want to test your function with some prints at this stage just to make sure the index chosen is correct (but don't leave those prints in the final version). 2.2 If you can assume that the x; values are uniformly spaced and you know the spacing, is there a fast and simple way to find the right index?
