.) Write a complete C program in one file which takes a double value from the user, cubes it, and prints the result. Your program must use a function which takes a parameter for the value to be cubed and returns the result by value. The function may not print anything or read anything directly from the user (i. e. no cin/cout in the function). Hint: n cubed is defined as n*n*n. Upload as cubeValue. cpp.
