Question

Write a C or C++ program a pseudo C program (based on chapter 2 in the book) and then use these programs to develop a MIPS program that gets an integer input from the user, and based on the input returns the minimal or maximal value stored in a static initialized array. The following are detailed instructions:

1) The program generates a static initialized array with 10 integers (using the .word directive). 2) The program prompts the user to enter 1 if she/he wants to find the minimal value stored in the array, and 2 if she/he wants the maximal value stored. 3) If the user enters 1, then the program finds the minimal value stored in the array and prints out this value. 4) If the user enters 2, then the program finds the maximal value stored in the array and prints out this value. 5) If the user enters any other value, then the program prompts him/her again to enter a valid number. 6) After displaying the min (or max), the program terminates.
