If you create and invoke a recursive function without accounting for a base case, what can go wrong?
oksian1 [2.3K]

Every recursive function should have an exit criterion (=handling the base case) to exit the recursion.

Without it, it wil recurse forever, until system resources run out (typically the call stack will overflow and your program will crash).

What is the range of values that a short can represent?
ikadub [295]

Answer:

c. Math.pow(-2.0,15.0) to (Math.pow(2.0,15.0) -1).

Explanation:

short represents a 16-bit signed integer. short is used to save memory because it occupies less space than integers where integers occupy 4 bytes short occupies 2 bytes.

Since it is signed so first bit is used to represent the sign if 0 then positive and 1 then the integer is negative.We are left with 15 bits.

So the range is -2¹⁵ to 2¹⁵-1.

Hence the answer is option c.

Explain in detail what this code does, Whats the flow in it, and whats the risk that its creating and what can i do to fix it? (
kodGreya [7K]

Answer:

The buffer has room for 499 characters (you always have to reserve 1 for the terminating \0 character).

The code copies all characters passed in the commandline (argv[1]) into this buffer without checking. If there are more than 499 characters supplied, these will be copied into a memory location that is not intended for it. This will probably cause your program to crash, but if the extra data is somehow executed by the processor as if it were a program, this could be a way to sneak a virus into your computer.

So, while copying data, it is important to always limit the maximum amount to the allocated space.
