Get that input. Use the equal sign as the terminator for user input. Then find out what operator the user used and perform caculations accordingly. Operators will be limited to "+, -, *, /, =". For example, the user input can be ABCD*E999= Then your output should look like: ABCD*E999=9CC44285 xxxxoxdddodxxddddd Although it appears similar to the last assignment, this time you should use jump tables to jump to the subroutines where calculations are performed. Also use jump tables to store 'x', 'd' ... For an A+ grade, your program should provide error handling. That is, if user input is illegal, you need to print out a message and start over again. Also, the program should compute the result--if the input string is meaningful,i.e., in the format above-- returning the value in either decimal or hexadecimal numerals at the discretion of the author.
