[Solved] How do I prevent a compiler warning when I assign a string literal to static char *argv[]

Question

While in pre-C++11 times implicit conversion from string literal (type const char[*]) to char* was only deprecated, since C++11 that’s an error (actually modifying it was UB earlier already).

Create a modifiable array and use that instead, like so:

static char argv_0[] = "pingpong";
static char *argv[] = {argv_0};

Be aware that the argument to main also has a sentinel null-pointer though.

If you are really sure they just got their const wrong, explicit casting may work too, though it’s a really dirty hack. Better refrain, and clean it up.
