Very very simple question with Char * type

[Chris3000]

I get an error like this : Unhandled exception at 0x004115ae in LesPointeur2.exe: 0xC0000005: Access violation writing location 0x00417a28.

I see that i cannot overwrite the "Hello World" like it is read only. "Hello World"
is like a constant but I don't want to. I never declare char const *MyString so
why I cannot directly change a char with my pointer CharPtr ?

I just want to know how I can do it with pointers.
No array or string solution please

 
char *MyString= "Hello World";
char *CharPtr;
 
CharPtr= MyString;
*CharPtr='m';
 
CharPtr++;
*CharPtr='o';
 
cout<<MyString;
 

Thanx

CharPointer is never pointed at modifiable data (it is not a good idea to modify string constants and on some systems causes errors).

MyString points to a string constant

you assign the value of MyString to CharPointer therefore CharPointer also points to a string constant.

If you want to modify what CharPointer is pointing to then it must point to modifiable memory.
