Practical C Programming

How it works...

The program will ask for two pairs of names and order numbers. In the first pair, we will deliberately generate a buffer overflow by entering text that is longer than the variable size, whereas for the second pair, we will enter the data within the specified range. Consequently, the information of the first user (pair) will be displayed incorrectly, that is, the data will not appear exactly the same as it was entered, whereas that of the second user will appear correctly.

So, we will define a structure called users with two fields or members called name and orderid, where name is defined as a string of size 10 bytes and orderid is defined as an int variable of 2 bytes. Then, we will define two variables user1 and user2 of ...
