Function MCQs

What is the result of compiling and running this code?

main()
{
      char string[] = "Hello World";
      display(string);
}

void display(char *string)
{
      printf("%s", string);
}

Determine output:

main()
{
      int i = 5;
      printf("%d%d%d%d%d", i++, i--, ++i, --i, i);
}

Pick the correct statements. I. The body of a function should have only one return statement. II. The body of a function may have many return statements. III. A function can return only one value to the calling environment. IV. If return statement is omitted, then the function does its job but returns no value to the calling environment.

}

}
