He never said it did. He said that "s" and "t" were modified.
Those are pointers to char, which he increments in each
loop iteration.


Yes he did. From the original message that started this thread

"On tracing the program i noticed that the strings "s" and "t" get
modified somehow in the comp function and as a result i am getting
incorrect results."

Notice "...the strings ... get modified...." In any event, it
probably means he was misinterpreting the output from his debugger.
When pointers s and t get modified (which we all agree is the actual
modification that occurs) to point past the terminating '\0'
characters, his debugger probably attempted to show him the "string"
at the new address. Since he was in the realm of undefined behavior
at this point, what the debugger showed was equally undefined and no
longer relevant to his question.
