Question

Assembly Language Programming In this assignment, you will iteratively populate a fixed-size integer array of 10 elements, array_a, with integer values provided by scanf. The user will enter 10 positive integer values, one per line, and the program will store the 10 values in array_a[0], array_a[1], …, array_a[9]. Once the 10 integers are entered, your program will print the array, then prompt the user for a search value which may or may not exist in the array. If the value exists, your program must print all locations where the value is stored. If the value does not exist in the array, it will display the message “that value does not exist in the array!”. After all output has been displayed, the program should exit (do not prompt for additional input).
