A modifier, also called a modifying

function is a member function that

changes the value of at least one

data member. In other words, an

operation that modifies the state

of an object. Modifiers are also

known as ‘mutators’. Example:

The function mod is a modifier in the

following code snippet:

class test

{

int x,y;

public:

test()

{

x=0; y=0;

}

void mod()

{

x=10;

y=15;

}

};
