Write a mixed-mode program that reads a string of characters as input and displays the

number of alphabetic characters (i.e., A to Z and a to z) and number of digit characters

(i.e., 0 to 9). The C main function prompts the user for a string and passes this string to

an assembly procedure (say, count), along with two pointers for the two counts to be

returned. The assembly procedure count calls the C library functions isalpha and

isdigit to determine if a character is an alpha or digit character, respectively.
