#include <iostream>
#include "format.h"

int main() {
  std::cout << format::string("{1}*{1} {0} {2}", "is", 4, 16) << "\n";
}

4*4 is 16

#include <iostream>
#include "format.h"

int main() {
  std::string out;
  format::append_value(out, 32);

  std::cout << out << "+" << out << " = "
            << format::value(64) << "\n";
}

32*32 = 64
