Question #: 114
Topic #: 4

Buffer X in an Accounting application module for Brownies Inc. can contain 200 characters. The programmer makes an assumption that 200 characters are more than enough. Because there were no proper boundary checks being conducted, Bob decided to insert 400 characters into the 200-character buffer. (Overflows the buffer). Below is the code snippet:

How can you protect/fix the problem of your application as shown above?

ABecause the counter starts with 0, we would stop when the counter is less than 200

BBecause the counter starts with 0, we would stop when the counter is more than 200

CAdd a separate statement to signify that if we have written less than 200 characters to the buffer, the stack should stop because it cannot hold any more data

DAdd a separate statement to signify that if we have written 200 characters to the buffer, the stack should stop because it cannot hold any more data

Definitely go with option D. Adding a separate statement to check if the buffer has reached its capacity is the most straightforward way to fix this issue.
