In C programming, function calls introduce a small overhead due to stack operations, parameter passing, and control transfer. While this overhead is negligible in most applications. But it can become significant in performance-critical systems such as embedded firmware, device drivers, and real-time applications. To reduce this overhead, the C language provides the inline keyword, which
