C++ Progrmaming Ch. 5 Stacks

** Please actually help! I have asked this question three times now and every response has not compiled and has many errors. ***

Develop an expression manager that can do a balanced symbol check.

Your program will read three different mathematical expressions from the user that are the followings:

string expression = "{(0+1)*(2+3)}";

string expression = "{(0+1)+[4*(2+3)]}";

string expression = "{(0+1)+[4*(2+3)}}";

As you notice the expressions contain the following symbols: { , }, ( , ), [ , ].

Write a program PEX5.cpp that after it reads the above expressions will check and report whether the expression is balanced or not.

Remember that { , }, ( , ), [ , ] are the only symbols that will be checked. All other characters will be ignored.

Remember to use the stack STL as you process each expression. Call the method that processes the expression as follows:

bool isItBalanced(string inputExpr)

If there is a mismatch in the expression make sure you report the symbol of the mismatch and its actual position in the expression.

Return to me the following file by dropping in the Dropbox for Assignment5: PEX5.cpp

Run:

Enter your expression: {(0+1)*(2+3)}

Expected output: {(0+1)*(2+3)} == 1

Enter your expression: {(0+1)+[4*(2+3)]}

Expected output: {(0+1)+[4*(2+3)]} == 1

Enter your expression: {(0+1)+[4*(2+3)}}

Mismatch found : } at 15

Expected output: {(0+1)+[4*(2+3)}} == 0
