Thanks Carlo! It worked out very well! How stupid I was to put that after Line 25!!!
One more question about free(list[x].studentName). As this variable is within the loop for memory allcation, and will be used for later print. How do I free it in this case? I am confused because of the loop and as member of the struct, which is a array pointer. Handling malloc() is my worst part with C!
Thank you again!

(1) one is to pass a pointer-to-pointer parameter, like:

{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)
