When do you need to match parentheses in C #?

Which is an example of a parenthesis matching?
Matching parentheses ( ( and ) ), brackets ( [ and ] ), and braces ( { and }) delimit various parts of the source code. In order for these parts to be interpreted correctly, the compiler must be able to determine how these different kinds of parentheses match up with each other. Another example is processing structured data stored in XML format.
When to use the stack algorithm for parenthesis matching?
When pop () ing we need to catch "going off the bottom" of the stack. By definition that means an index less than zero. That algorithm definition is accurately coded as ptr < 0 . Given the above, if ptr is -2 - this is not a program error per se. The program will keep running correctly.
Why is my parenthesis not matching in Python?
If this operation fails because the stack is empty, it is because there are too many close parentheses (no corresponding open parenthesis was previously placed on the stack). Moreover, if the stack isn't empty after parsing the entire string, it is because there are too many open parentheses (which never got popped off the stack).
