法学研究C++ 程序将单位为 km/hr 的速度转换成 m/sec，反之亦然
转换公式 −
1 km/hr = 5/18 m/sec or 0.277778 m/sec 1 m/sec = 18/5 km/hr or 3.6 km/hr
实例
Input-: km = 60.00 mk = 70.00 Output-: speed in meter per second = 16.6667 speed in km per hour = 252
算法
Start Step 1 -> Declare function to convert km/hr into m/sec float km_m(float km) return (0.277778 * km) Step 2 -> Declare function to convert m/sec into km/hr float m_km(float mk) return (3.6 * mk) step 3 -> In main() declare variable as float km = 60.0 and float mk = 70.0 Print km_m(km) Print m_km(mk); Stop
实例
#include <bits/stdc++.h>
using namespace std;
//function to convert km/hr into m/sec
float km_m(float km){
return (0.277778 * km);
}
//function to convert m/sec into km/hr
float m_km(float mk){
return (3.6 * mk);
}
int main(){
float km = 60.0;
float mk = 70.0;
cout << "speed in meter per second = " << km_m(km)<<endl<< " speed in km per hour = " << m_km(mk);
return 0;
}输出
speed in meter per second = 16.6667 speed in km per hour = 252
