Simple method to output CLI arguments in C++

main.cpp

#include <iostream>

void printArgs(const int argc, const char *argv[])
{
  std::cout << "argc: " << argc << "\n\n"
            << "argv:\n";
  for (unsigned int i{}; i < static_cast<unsigned int>(argc); ++i)
    std::cout << "- " << argv[i] << '\n';
}

int main(const int argc, const char *argv[])
{
  printArgs(argc, argv);
  return {};
}
