C++ 程序将公里每小时转换为英里每小时，反之亦然

输入若是 km/hr，则将它转换成 miles/hr；否则输入为 miles/hr，则将其转换成 km/hr。有可用于进行此转换的公式。

转换公式−

1 kilo-metre = 0.621371 miles
1 miles = 1.60934 Kilo-meter

示例

Input-: kmph= 50.00
   Mph = 10.00
Output-: speed in m/ph is 31.07
   speed in km/ph is 16.0934

算法

Start
Step 1 -> Declare function to convert km/ph to m/ph
   double km_mph(double km)
      return 0.6214 * km
step 2 -> Declare function to convert m/ph to km/ph
   double m_km(double m_ph)
      return m_ph * 1.60934
step 3 -> In main()
   declare variable as double kmph = 50 and double mph = 10
   print km_mph(kmph)
   print m_km(mph)
Stop

示例

#include <bits/stdc++.h>
using namespace std;
// convert km/ph to m/ph
double km_mph(double km){
   return 0.6214 * km;
}
//convert mph to kmph
double m_km(double m_ph){
   return m_ph * 1.60934;
}
int main(){
   double kmph = 50.00;
   double mph = 10.00;
   cout << "speed in m/ph is " << km_mph(kmph) << endl;
   cout << "speed in km/ph is " << m_km(mph);
   return 0;
}

输出

speed in m/ph is 31.07
speed in km/ph is 16.0934
