7.(6 points) (Engineering P6.31) Sample values from an experiment often need to be smoothed out. One simple approach is to replace each value in an array with the average of the value and its two neighboring values (or one neighboring value if it is at either end of the array). Implement a function void smooth(doublel ] values, int size) that carries out this operation. You should not create another array in your solution. Create a program (moving,average 1.cpp) with main)that will test smooth0. on bottom.) Test cases: (L on top: 40.8216.62
