input_10_numbers_and_find_indexValue.asm

; Write an assembly program that reads 10 numbers from the user. The program then reads
; a number between 0 to 9, and shows the number at the corresponding index number. For
; instance, if the array is a and the user enters 3, your program should print the value at
; position 3.
