Expert Solution

void idkwhattonameit( const name) {}

const name means the name parameter is used only for read only purpose.. we can't modify the name value but it will be no use if we use it on call by value

void idkwhattonameit2( const &name) {}

const name means the name parameter is used only for read only purpose.. we can't modify the name value but we can use it

void idkwhattonameit3( const * name)

here we made pointer as const than we can't change the address of variable name
