How can I search for data in a linked list?
Unfortunately, the only way to search a linked list is with a linear search, because the only way
a linked list’s members can be accessed is sequentially.
Sometimes it is quicker to take the data from a linked list and store it in a different data
structure so that searches can be more efficient.

Answer: Linker Error : Undefined symbol '_i'
Explanation: extern storage class in the following declaration,
extern int i;
specifies to the compiler that the memory for i is allocated in some other program and that
address will be given to the current program at the time of linking. But linker finds that no other
variable of name i is available in any other program with memory space allocated for it. Hence a
linker error has occurred
