Read Access Violation. Web 1 answer sorted by: } you could be calling toupper to change to upper case and assigning the value back to *sname instead of having the function call itself.
Add your program to an exception access list. So, i get through adding to the front twice, and creating the new node insert_rear () as well as the first iteration of the while loop. I'm guessing there's no device at that address to read from because test is an empty string. Inserting new item at end of list. Web the following segmentation violation occurs when you submit a data step that contains a where clause for a view that has a concatenation operator. You will only be writing/reading the pointer values, not the actual character data. } but from this code we can see there's really no reason to use a pointer. (remmember, c doesn't have strings, it has character arrays.) then, in your second loop, you get an access violation because you're trying to index past the end of the array.

You have to allocate a b with make_shared: List is not empty, and there is no tail. While (*sname != '\0') { stringtoupper (* sname); Web 1 answer sorted by: You have to allocate a b with make_shared: If there is a handler for this exception, the program may be safely continued.
