C++ Functions

Write a program that inputs three integers from the keyboard and prints the sum, average, product, smallest and largest of these numbers . declare a structured called minmax that includes two jnt type variables called minvalue and declare and define a function called calcsum() that returns the summation of three integer values; The function takes three jnt type variables as arguments. . declare and define a function called calc average) that returns the average of three integer values. The function takes three int type variables as arguments. . declare and define a function called calcproduct() that returns the product of three integer values; The function takes three jnt type variables as arguments. declare and define a function called calc minmax() that returns a minmax type variable that holds the smallest and largest values among three integers. The function takes three int type variables as arguments . define a main() method to ask the user to provide three integer values from the keyboard. Note: the three integers can be input in 13 27 14 format, or each number can be entered at a separate prompt. in the mainc) method, print the sum, average, product, smallest and largest of these numbers The screen dialog should appear as follows
