Numbering exception conditions, which often uses hierarchical numbering, in a fully developed use case description is helpful to . a. tie the exception condition to a processing step b. show which exception conditions are subordinate to other exceptions c. provide an identifier for each exception condition d. tie exception conditions to other diagrams or descriptions

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
