Implement the syntax checking parser application involving a stack

INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

Implement the syntax-checking parser application involving a stack. Read in a string that may include the symbols ‘(’, ‘{’ and ‘[’ and their “closed” counterparts.  If they are closed out of order, or if a close is missing, or if there is an extra close symbol, the program should report an error. In the sample below, the bold text is user input.  You may assume a maximum string size of 25 characters.

Zip this with your completed document and upload to the link provided on Moodle.

Sample Output

This program checks for syntax errors involving open-close pair symbols.

Please enter a string, with “quit” allowing the user to exit the program:

(a + b) * g

The above string is correct.

Please enter a string, with “quit” allowing the user to exit the program:

(a + b) – random string }

There is an error in the above string.

Please enter a string, with “quit” allowing the user to exit the program:

((a * b) + u

There is an error in the above string.

Please enter a string, with “quit” allowing the user to exit the program:

{a + [g * f }]

There is an error in the above string.

Please enter a string, with “quit” allowing the user to exit the program:

quit

Bonus: 5% if the parser can identify the kind of error (open with no close, close with no open, closings out of order).
