Modifying string inside a method

[rajimrt]

Hi,
I want to change the string inside a method. I wrote following code but it won't do it.

void change_string(const char * the_string)
 {
    cout << the_string << endl;
    the_string = another_string();
 }

int main()
{
const char *pzMyStr = "Hello";
change_string(pzMyStr);
cout << pzMyStr << endl;
}

Hello
Hello

I want that second output to be Another string. I want to do it without string objects.

Do you know what constant means? And do you know what a char* and a char array are?

[rajimrt]

Yes I know what const char * means. it means I can change the char to which the_string points, but I cannot modify the char at which it points.

[hanst99]

And you want to modify the string, not the pointer. That's why passing a const char* is meaningless.

I don't want to modify it. I want to allocate new location for that char pointer. Having const will not restrict that.
