C++ deprecated conversion from string constant to 'char*'

Question

I have a class with a private char str[256];

and for it I have an explicit constructor:

explicit myClass(const char *func)
{
    strcpy(         


        

Answer 1

The warning:

deprecated conversion from string constant to 'char*'

is given because you are doing somewhere (not in the code you posted) something like:

void foo(char* str);
foo("hello");

The problem is that you are trying to convert a string literal (with type const char[]) to char*.

You can convert a const char[] to const char* because the array decays to the pointer, but what you are doing is making a mutable a constant.

This conversion is probably allowed for C compatibility and just gives you the warning mentioned.
