Explanation / Answer

48)Answer:

In C, nothing happens, because array values cannot be assigned.

If you mean initialization rather than assignment, then that’s a constraint violation, meaning that any conforming compiler is required to diagnose it. (The diagnostic may be a non-fatal compile-time warning.) An example of this is:

If you mean indirectly assigning an array using memcpy or memmove, attempting to copy past the end of any object has undefined behavior. The compiler is not required to diagnose the error, and the run-time behavior can range from doing nothing to crashing your program to yielding arbitrary incorrect results. It’s up to the programmer to avoid doing that

49)Answer:

In C++, the null character is represented as ''
