The implementation of the Banker's algorithm for deadlock avoidance is a fundamental concept in operating systems, ensuring resource allocation safety in multi-process environments. The core objective of the algorithm is to determine whether the system can allocate resources to each process based on their maximum claims, current allocations, and available resources without entering a deadlock state. This paper presents a detailed explanation of the algorithm, its implementation in C, and its practical application through a sample code that processes input data from a file to evaluate system safety.

The Banker's algorithm begins with understanding the initial state of the system, including the total available resources, the maximum resources each process may claim, the current allocation of resources to each process, and the remaining needs of each process to complete execution. These inputs are essential for the safety check, which involves simulating process execution sequences. The algorithm iterates through processes, checking if the remaining needs of a process are less than or equal to the current available resources. If so, it assumes the process completes, releases its allocated resources, and updates the available resource pool. The process repeats until all processes are accounted for or no further processes can proceed safely, indicating whether the system is in a safe state or not.

The C implementation of this algorithm involves reading structured input data from a text file specified by the user. The input file contains the number of processes and resource types, the total available resources of each type, the maximum claim matrices, current allocation matrices, and thus, the need matrices. The program then systematically performs the safety check as per the Banker's algorithm, utilizing nested loops and proper condition checks. It outputs whether the system is in a safe state, along with a safe sequence if one exists, or otherwise indicates the presence of a potential deadlock.

To exemplify the correctness and utility of the implementation, a sample input file is used, and a screenshot of the program’s output is provided. This demonstrates how the program interprets data and applies the safety algorithm step-by-step, ensuring clarity and reproducibility. The visual confirmation via a screenshot verifies the correct functioning of the code, validating that the algorithm effectively prevents deadlock conditions by only granting resource requests deemed safe.

This implementation emphasizes modularity, readability, and robustness, accounting for edge cases such as the initial safe state, maximum resource claims, and partial allocations. The program also provides insightful feedback to the user, illustrating the sequence of process completions and the remaining resources at each step. Such an approach not only reinforces theoretical understanding but also offers practical tools for managing process scheduling in operating systems, ultimately reinforcing system stability and efficiency.
