Program that reads expressions over binary operators

Assignment Help Basic Computer Science
Reference no: EM13856796

Write a program that reads expressions over binary operators +, -, *, /, ^ and parenthesis from the standard input and displays the result of evaluating the input expression to the standard output. The program must first read the priorities and associativities of each operator from the standard input. For example the following input lines describe the standard priorities and associativities

- 1 L
+ 1 L
* 2 L
/ 2 L
^ 3 R

  • Each expression is terminated by a new line
  • Operands are all integers and all operators perform integer operations
  • Your program must display an error message in case of an erroneous expression and continue to the next expression
  • The end of input is signaled by end of file (CTRL D) The program must be completed using algorithms discussed in class (using a stack that is implemented with pointers). Other methods (and possibly correct) programs will not be considered correct!!
