A. Exceptions are not suitable for critical points in code
B. Exception are suitable for critical points in code
C. Exceptions are used when postconditions of a function cannot be satisfied

Q: What can go wrong in resource management on c++?
A. Leakage
B. Exhaustion
C. Dangling
D. Exception
Solution: If there is any mishap in memory or resource management means, the problems that are mentioned above can happen.
Q: When do we call that resource is leaked?
A. Arise of compile time error
B. It cannot be accessed by any standard mean
C. Arise of runtime error
D. It can be accessed by any standard mean
Solution: Resource is said to be leaked when it cannot be accessed by any means of standard mean.
Q: What kind of error can arise when there is a problem with memory?
