Differences between strings in VC5 and 6
Author
Does anybody knows why this crashes my program in VC6? It worked in VC5.
char *test3="This is test number 2";
test3[21]='3';
It's for replacing a character in a string.

Hmm, maybe because your changing the ''\0'' to ''3'', remember your index''s start at 0 not 1, so the last index is 20.

Maybe i''ve miscount here, it''s a example, but even if I want to change the second letter or so, it crashes
You''re editing a constant string in memory, in VC5 it must of not checked if it''s constant. If the change the code to for example
char SomeString[] = "Some text";
It should work, and here''s why, instead of allocating a static area of memory that can''t be edited then assign a pointer to it, the compiler tells the program to allocate an array like normal then fills it with the text given, which allows you to edit it.
char SomeString[] = "Some text";

Well then id just say its another problem with the compiler then, but still if your going to use pointers allocate some memory before assigning them a value!

thnx xDS4Lx and Omalacon, the char SomeString[] was the solution. And you''re right, I should allocate the memory first, but these are a just a few tests with string manipulation, memory management will come later
