Given this class declaration:

class Socks

$\{$

private:

char size;

string brand;

string material;

public:

void setsize$($char newsize$)$;

void setBrand$($string newBrand$)$;

void setMaterial$($string newMaterial$)$;

char getsize$()$;

string getBrand$()$;

string getMaterial$()$;

$\}$;

And declaring an object named mySocks, which of these would not be a valid function call.

mySocks.setMaterial$($string "Cotton"$)$;

mySocks.getBrand$()$;

mySocks.getMaterial$()$;

mySocks.setBrand$("$Hanes$")$;
