writeable-strings (gcc 4 and lower versions) clarification

[sting sting]

Hello,

If you will comple with gcc (version lower than 4) a program like this , on 
Linux:

int main()
     {
      char* myString = "test";
     (*myString)++;

     }

You will get a segfault when running it.
On the other hand, if you will pass -fwriteable-strings at compilation ,
you will be able to run it without any segfault .
They do say in the man gcc that writeable-strings is deprecated and it is 
better not to
use it.

According to gcc-4.0 docs,
"GCC no longer accepts the -fwritable-strings  option. Use named character 
arrays when you need a writable string."

see
http://gcc.gnu.org/gcc-4.0/changes.html

I have 2 questions:

What are the disadvantages of using -fwritable-strings and why was it 
removed ?


by "Using named character arrays" I assume that the meaning is
writing   char myString[] = {"test"};

am I right ?

Regards,
Sting
