Having trouble running a do while with a if else statement. I'm getting an error saying the "variable 'distanceM' is being used without being initialized."

``````int main ()
{
const double PI = 3.141592;
char choice;

cout << "This program converts a set of polar coordinates ( M , theta in degrees ) to" << endl;
cout << "their rectangular equivalents ( x, y), or a set of of rectangular coordinates" << endl;
cout << "to their polar equivalents." << endl;

cout << "\nEnter the first coordinate ( x or M): ";
cin >> xM;
cout << "Enter the second coordinate ( y or theta ): ";
cin >> yTheta;

cout << "Enter r or R if these are Rectangular";
cout << "\nor p or P if they are polar: ";
cin >> choice;

do
{
if ( 'r' == choice)
{
distanceM = sqrt((pow(xM,2))+(pow(yTheta,2)));

cout << "\nThe Polar Coordinates ( M, theta ) are ( "<< fixed << setprecision(2) << distanceM <<" , "<< thetaDeg <<" )";
}
else if ( 'p' == choice)
{

cout << "\nThe Rectangular Coordinates ( x, y ) pair is ( "<< fixed << setprecision(2) << X <<" , "<<Y<<" )";
}
else
break;
} while(1);

getchar ();
return (0);
}``````

Can anyone help me out?

This program doesn't calculate distancem when p is pressed. Try moving line 24 outside if statement.

Thank you i jus noticed my error distanceM on line 34 & 35 is supposed to be variable Xm. Now im getting an issue though with my do while loop it won't break

You are reading input only once, it should be in loop.
