OK you just made a simple error.

Change all of your if statements to

if (text== ''m'') {

}

etc.

There are two equal signs in a comparison in c++.

yes, that won''t give an error though. I used to void main as well when i first started with c++.

The only thing i can see that would cause that is the single =.

Depending on your compilier this should generate a warning along the lines of "Possible incorrect assigment". This should be a good lesson on making sure you check those warnings.

A warning for that would probably be annoying, since often assignment is your intent (like for error checking a variable right after it is assigned a value).
