Write a C++ program that does the following:
 Display your company name “<Your full name>’s Space Travel Company”
 Read a three-digit spaceship identification number, captain’s name, and an int cargo amount for each of the four cargo categories.
 Compute the cost for each of the four cargo categories, use double for cost.
o The cost for each cargo category MUST be computed in a function. There will be only one function to calculate this cost. The function will be called four times (once for each cargo category). The prototype of this function is: double calcCost(int cargoAmount, double pricePerUnit);
 Print the spaceship identification number and the captain’s name.
 For each of the four cargo categories, print the description, the sales amount, and the cost in column format using a void function. The function is to print only one description, sales amount and cost. It is to be called four times (once for each cargo category).
 Print the total paid to the company.
 Continue looping (requesting a new spaceship id) until -999 is inputted for spaceship identification number
