What is the result of compiling and running this code? main() char string[] = "Hello World"; display(string); void display(char *string) printf("%s", string);

Answer: Option B

Compiler Error : Type mismatch in redeclaration of function display
As the function display() is not defined before use, compiler will assume the return type of the function which is int(default return type). But when compiler will see the actual definition of display(), mismatch occurs since the function display() is declared as void. Hence the error.
