C++ Exercises: Converts kilometers per hour to miles per hour
C++ Basic: Exercise-23 with Solution
Write a program in C++ that converts kilometers per hour to miles per hour.
Pictorial Presentation:

Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
int main()
{
float kmph, miph;
cout << "\n\n Convert kilometers per hour to miles per hour :\n";
cout << "----------------------------------------------------\n";
cout << " Input the distance in kilometer : ";
cin >> kmph;
miph = (kmph * 0.6213712);
cout << " The "<< kmph <<" Km./hr. means "<< miph << " Miles/hr." << endl;
cout << endl;
return 0;
}
Sample Output:
Convert kilometers per hour to miles per hour : ---------------------------------------------------- Input the distance in kilometer : 25 The 25 Km./hr. means 15.5343 Miles/hr.

Why is there no std::stou?
The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
