Thank you so much for your patience with my basics still, as I feel getting better to understand more. strncpy doesn't want the size of the origin string: It wants the size of the destination buffer. ...... If you'd used strcpy, you would have been safe.
To see how things are working in the memory in order to understand those garbage left, I got error in the Block Two of following code:***buffer overflow detected ***: ./memset01 terminated
If I switch the two blocks, there is no buffer overflow for the memset().
What is going on in the memory? Thanks!

printf("\nPlease enter your name: ");
cin >> name;
