What is integer overflow, and how does it occur in C or C$++?$ Can you provide an example of a situation

where integer overflow can lead to a security vulnerability?

$2.$ Explain the differences between signed and unsigned integers in C or C$++.$ How can using unsigned

integers help prevent certain security issues?

$3.$ What is integer truncation, and how can it pose a security risk? Give an example of code where integer

truncation might lead to unexpected behavior.

$4.$ List some best practices for handling integers securely in C and C$++.$ How can developers ensure that

their code is resilient against integer$-$related attacks?
