Just studying old exams, got some questions.



My output:

2)
a. 10
b. 0
c. 2 (why is this 2?)
d. unknown (prints to address &a)
e. Not sure?
f. Not sure?

And another problem:

1-c. Assume that s and t are both valid strings and both end with a null character. Under what circumstances
will the expression strlen(s) - strlen(t) produce inconsistent or incorrect results? And
how can the problem be avoided?

I believe the null character isn't included in the calculation for strlen(), so I'm not really sure what scenario this would cause issues.

Update on #2:

b ) 11
f) unknown (since what your incrementing just points to an address &p?)
e) still not sure

Nvm figured out how they work
