Write the prototype of a function check which takes an integer as an argument and returns a character.
Topic: Method prototypes

Answer
Exam answer
char check(int n) (public static char check(int n) is equally acceptable.)
Explanation
A prototype states three things in order: the return type, the name, and the parameter list.
returns a character → char
named check → check
takes an integer → (int n)
Read such questions twice — once for what goes IN, once for what comes OUT — because the two are easily swapped. Access specifiers such as public are optional unless the question asks for them.
