Write a program that defines three objects of type const int, const double and const std::string, respectively.
Define a fourth const int object and initialize it with a value of the first const int object.
Print out the values of all the variables.
You can use the following code structure.
#include <iostream> int main() { //your code here }
#include <iostream> int main() { const int c1 = 123; const double d = 456.789; const std::string s = "Hello World!"; const int c2 = c1; std::cout << "Constant integer c1 value: " << c1 << '\n'; std::cout << "Constant double d value: " << d << '\n'; std::cout << "Constant std::string s value: " << s << '\n'; std::cout << "Constant integer c2 value: " << c2 << '\n'; }
