When trying to print the first command line argument:
std::cout << argv[0] << std::endl;
clang-tidy gives the warning:
warning: 'do not use pointer arithmetic' from [cppcoreguidelines-pro-bounds-pointer-arithmetic]
Is there an alternative way to use the values of argv without using pointer arithmetic? Isn't accessing a char** by any sensible method going to have to use pointer arithmetic?
I appreciate there are some specialised functions to handle command line arguments, but they seem too heavyweight for simply printing one argument.
I am writing in c++, using the clang compiler and building with cmake.
