I am having several errors when compiling my code :     #include <iostream>

    int main ()
    
    { 
   
    	double uData, mData, lData, subTotal, tAmount, fTotal, ssTotal, pLines;
    	char dataType, miitaryY, militaryN

    		subTotal = ssTotal + pLines + uData
    		fTotal = (subTotal * tAmount) + subtotal
    	}
    	else if (militaryN)

    	}
    	else if (militaryY)
