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
