Thread: Some wierd errror I don't understand

I want to make a simple singly linked list. The conversion constructor in the class "slist" is slist(const char* c) and I want it to just take a string, reverse it, and prepend it so that each letter in the string is a node in the linked list.

Conversion Constructor

Code:

slist::slist(const char* c)
{
     int i;
     int len = strlen(c);
     char temp;
     
     for (i = 0; i < len/2 ; i++){     //Stops when half the string is reached
		temp = c[i];                       
		c[i] = c[len-1-i];                 //First char is set to last
		c[len-1-i] = temp;                 //Last char is set to first
	 }

     
     for(i = 0; i < len; i++)
             prepend(c[i]);
}

The error I'm getting says that on these lines...

Code:

		c[i] = c[len-1-i];                 //First char is set to last
		c[len-1-i] = temp;                 //Last char is set to first

"assignment of read-only location"

What does that mean? Tell me if you need more code like the class or any other functions.

oh....

....duh

SGI (and probabaly Boost) already has an slist.
