dereference


Char pointer dereference


I try to change uppercase to lowercase in the sentence represented by char *.
I get an error: access violation when I make pointer dereference.
// Uppercase to lowercase
char *str = "My sentence";
*str = 'm';
The reason is that you have used the wrong format to define a string. You want:
char str[] = "My Sentence";
*str = 'm';
What you have written defines a pointer and then assigns "My Sentence" to the pointer as a memory address. You are receiving an access violation because you do not own the memory at "My Sente" which is most likely the address being referenced.
