c++

I need help writing a program that reads a set of floating-point values. It needs to ask the user to enter the values, then prints >the average of the values >the smallest of the values >the largest of the values >the range (the difference between the smallest and largest) the program may only prompt for the values once.

the program needs to be in C++..thank you

output should like

Enter numbers ( Q when done ) : 1.5 3 4 2 Q

Average : 2.625

Smallest : 1.5

Largest : 4

Range : 2.5

Enter numbers ( Q when done ) : -7.2 Q

Average : -7.2

Smallest :- 7.2

Largest : -7.2

Range : 0
