Banker’s Algorithm C Program

C Program To Implement Banker’s Algorithm

Learn How To Write A C Program To Implement Banker’s Algorithm for avoiding Deadlocks in Operating Systems. Banker’s Algorithm is also popularly known as Deadlock Avoidance Algorithm.

What is Banker’s Algorithm?

The Banker’s Algorithm was designed and developed by a Dutch Computer Scientist, Edsger Djikstra. The Banker’s Algorithm is a Resource Allocation and a Deadlock Avoidance Algorithm.

This algorithm takes analogy of an actual bank where clients request to withdraw cash. The Banking Authorities have some data according to which the cash is lent to the client. The Banker cannot give more cash than the client’s request and the total cash available in the bank.

Banker's Algorithm in C Programming

The Banker’s Algorithm is divided into Two parts:

1. Safety Test Algorithm: This algorithm checks the current state of the system to maintain its Safe State.

2. Resource Request Handling Algorithm: This algorithm verifies if the requested resources, after their allocation to the processes affects the Safe State of the System. If it does, then the request of the process for the resource is denied, thereby maintaining the Safe State.

A State is considered to be Safe if it is possible for all the Processes to Complete its Execution without causing any Deadlocks. An Unsafe State is the one in which the Processes cannot complete its execution.

    Thanks. Finally this Bankers Algorithm CProgram works. Is the Banker Algorithm used in real time in Banking Systems? Or is there any new algorithm that has replaced Banker’s Algorithm?

    It is important to check if the wait for graph contains a cycle or not. If it does not contain any cycle, then there is no deadlock possibility.

    I think the Bankers algorithm and Dijkstra’s algorithm has some similarities since its is developed on the basis of Dijkstras algorithm.

    The Banker’s Algorithms offers the following conditions:
    1. No Preemption
    2. Hold and Wait
    3. Mutual Exclusion
    However, it prevents the processes from going into the circular wait condition.

    Whenever the system receives a request for granting resources, it executes the Banker’s algorithm amd displays whether it is safe to grant the request or not.

    The Banker algorithm for deadlock avoidance in C programming is I feel very old technique. There are many newer and better algorithms for deadlock avoidance techniques.

    I wonder if the Banker’s Algorithm is implemented in the banks at the time when Rs. 500 and Rs. 1000 notes are demonitized.
