I keep getting the error:

"modification of 'gender' is not a constant expression case gender = 'm'"

How can I fix my code?

bool getGender()

{

bool gender;

cout << "Are you a male or a female (m/f)?";

cin >> gender;

switch(gender)

{

case gender = 'm':

case gender = 'M':

return false;

case gender = 'f':

case gender = 'F':

return true;

break;

default:

cout << "Please type m for male or f for female: ";

}

return gender;

}
