Answer 1

std::cin.ignore() is fine, although only discarding a single character might not always be enough.
However, you forgot to include the <cstring> header, and strcpy() does not take the number of characters as argument (strcpy_s() does not appear to be available on SoloLearn).
The INT_MIN macro is not defined unless you include the <climits> header, and your logic to determine the best student is incorrect, since you are mixing average marks and numbers when comparing the students.

Here is a working code:
