For each of these exercises follow the cdecl protocol for the specified procedure and write a short console32 or windows32 test-driver program to test the assembly language procedure.

1. Suppose that a procedure is described in C/C++ by void toUpper(char str[]), that is, its name is toUpper, and it has a single parameter that is the address of an array of characters. Assuming that the character string is null-terminated, implement toUpper so that it changes each lowercase letter in the string to its uppercase equivalent, leaving all other characters unchanged.
