using visaul studio c programming inside a do while loop ask user to enter two numbers (use a single scanf function). Inside the same loop ask the user whether they wish to find the min or max of the values entered. If the user enters a 0 call the minFunction; if the user enters a 1 call the maxFunction; otherwise print Not valid input. Pass the two numbers entered as parameters to the functions. Inside minFunction and maxFunction calculate the minimun and the maximum values, respectively, and print. Break the loop when the user enters -999 -999 (values such as -999 are used as a sentinel to terminate a program)
