Cval and Pval

Create a program with 3 functions:

(i) main()
(ii) calculateCval()
(iii) calculatePval()

ex. calculateCval should have:

double calculateCval(double S, double K)

calculateCval will calculate max(0, S - K) (A)
calculatePval will calculate max(0, K S) (B)

main:

(i) Ask user to input S, K using (cin) and print out calculateCval and calculatePval using the equations A and B.

(ii) Run a loop where S ranges from 70 to 120 in increments of 1 and print out the same as in step (i) for K = 100

(iii) Run a loop where K ranges from 70 to 120 in increments of 1 and print out the same as in step (i) for S = 111

(iv) Use 'if' statement for conditional execution:

(a) Ask a user to enter 0 or 1
(b) Is user enters 0, then ask user to enter a S value and calculate value using equation B with K = 100
(c) If user enters 1, then ask user for a K value and print out value using equation A for S = 60
(d) If user enters something else print 'error'.
