Practical C Programming

How it works...

To enter the name and order number of a customer, define a structure called users with two members, name and orderid. The name member is a character array or string of 10 bytes in length, and the orderid member is a variable of the int data type consisting of 2 bytes.

A variable, user1, is defined as the users structure type; hence, the user1 structure will get two members, name and orderid. An integer value 101 is assigned to the orderid member of user1 structure. Also, a string, administrator, is assigned to the name member of user1. Because the string administrator is larger than the size of the name member, a buffer overflow will occur, overwriting the memory of the next memory location, that is, of the orderid member.  ...
