[M] Write an IA-32 program to solve Problem 2.29 in Chapter 2.
Problem 2.29
[M] Write a subroutine called EXCLAIM that accepts a single parameter in a register representing the starting address STRNG in the main memory for a string of ASCII characters in successive bytes representing an arbitrary collection of sentences, with the NUL control character (value 0) at the end of the string. The subroutine should scan the string beginning at address STRNG and replace every occurrence of a period (‘.') with an exclamation mark (‘!').
