If the value of price is greater or equal to 0, proceed as follows: If the value passed by price is smaller than the current value of price_, the function should assign price to price_ and return -1. If the value passed by price is larger than the current value of price_, the function should assign price to price_ and return 1. If price is equal to price_, the function should assign price to price_ and return…

I also need help in writing the definition of the member function manipulation that returns a decimal with: the value of the description as "rectangle", returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of the description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns with the value -1.

Write a function getNeighbors which will accept an integer array, size of the array and an index as parameters. This function will return a new array of size 2 which stores the neighbors of the value at index in the original array. If this function would result in returning garbage values the new array should be set to values {0,0} instead of values from the array.
