UMBC CMSC211

Project 6 Due: 15 May

Requirements Specfication

Write a C program that will ask the user to enter a message of some length. The length must be long enough for the user to enter a full line of text. Then pass the message to a function named ConvertMessage, which has the prototype of:

void ConvertMessage( char message[], int size );

The function will convert every uppercase letter in the message to a lowercase version, and will convert the uppercase letters to lower case. The entire body of the function is to be written in assembly language. Remember that Visual C++ assumes that the model is bigger than small and that the processor is at least a 80486, with extended registers. return to C and return to main( ). In main( ), print out the converted message.

Only convert letters, do not convert any other symbol!

Sample Output
