Thread: constant strings

    constant strings

    I know there is a potential problem with doing the following due to read only memory:
    char * szString = "Test";
    szString[2] = 'd';
    What about the following?:
    void Func(char * szString) {
       szString[2] = 'd'
    char * szString = "Test";
    Does the compiler make sure the string is not put into read only memory in this scenario or do I have to copy the string in the function. This works without problems at the moment but I thought I would check with the experts.

    It's still a problem. You need to make sure your program writes to memory it's allowed to, the compiler won't do that for you in this case.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
