Write a program that calls a function to change a variable value from miles to kilometers.

#include <iostream>

using namespace std;

void miles_to_km(float &miles)//function to convert miles to kilo meters.

{

   miles=miles*1.6;

}

int main() {

   float miles;

   cout<<"Enter the miles"<<endl;

   cin>>miles;//taking input of the miles..

  miles_to_km(miles);//calling function that converts miles to km..

   cout<<"The number of km is "<<miles<<endl;//printing the km.

return 0;

}

Output:-

Enter the miles

54

The number of km is 86.4
