a) The conversion ratios are predefined and stored in variables of the type
double. For example:
double FtoM = 0.3048; // Ratio for converting feet into meter
double MtoKM = 1.852; // Ratio for converting mile into kilometer

b) User inputs a conversion request which consists of a code representing the
type of conversion and an amount to be converted.
For example: 1 2000 represents a request to convert 2,000 feet into its
equivalence in meters.

c) Your program will perform the conversion based on the predefined ratios and
prints the converted amount (to 2 decimal places) on the screen.

提示：
最终输入 ： 1 2000  会显示609.60

你还没写完吧？
请详细点

就是做个转换啊
