Question

P1 - Circle Area and Circumference functions.cpp, functions.h, P1.cpp The user enters 3 floating-pointer numbers which correspond to 3 radi. Store these numbers in an array. Then, define and prototype a function void area and cireffloat* area, float circumference, float array) which takes as input the array of circumferences of circles with the input radii. Think about why we need to pass pointers for both the area and the circumference variables. radii and returns an array of areas and an array olf Structure your code into three files: functions.cpp Define the area and circ function here. Furthermore, define a function bool contains a negative radii(float array) which returns true (1) if the input array contains one or more negative values and false (0) otherwise. functions.h Prototype the functions here. P1.cpp Here define the main0 function. Also, use proper #include statements. The program should only terminate if one or more of the input radii are negative (while loop!). The main function should read the 3 numbers from the user into an array, and then call the contains a negative_radii function, If the function returns false, call area and cire function Then print the calculated area and circumference for each circle. Sample Output: Enter three radii: 123 Circle 1 Area 3.14159 Circle 1 Circumference 6.28319 Circle 2 Area 12.56637 Circle 2 Circumference 12.56637 Circle 3 Area 28.27433 Circle 3 Circumference 18.84956 Enter three radii: 1-2 3 Contains a negative radii.
