parenthesis checking...

[zhinokin]

hi to everyone...

i will make a program about parenthesis checking and my prof said that we will not be using a stack for this.

will you kindly help me to this..

aside from stack can you help me on what to use.?.

So use a counter.

So use a counter.

should i still use an array for this....?..

[Salem]

counter += 1*(ch=='(') - 1*(ch==')');

It's cryptic because anything simple is the whole answer on a plate.
