Since the parameter 'height' is to be inputted from the keyboard and all the other parameters defend upon the value of 'height', you need not to declare the value of 'height' from the beginning (height=0). Instead just initialise thae variables as in;
Int height;
And since 'feet' is a fraction it should either be of type 'float' or 'double' i.e double feet;
double inches;
GOOD LUCK!
