36.1 static_cast Conversion

Write a program that uses a static_cast function to convert between fundamental types.

#include <iostream>

int main()

{

    int x = 123;

    double d = 456.789;

    bool b = true;

    double doubleresult = static_cast<double>(x);

    std::cout << "Int to double: " << doubleresult << '\n';

    int intresult = static_cast<int>(d); // double to int

    std::cout << "Double to int: " << intresult << '\n';

    bool boolresult = static_cast<bool>(x); // int to bool

    std::cout << "Int to bool: " << boolresult << '\n';

}
