Through three focused experimental models—task scheduling, signal-based interrupt handling, and deadline-based performance evaluation under stress—we demonstrate C's capabilities and boundaries in real-time contexts. The experiments measure task execution durations, interrupt response latencies, and behavior of deadline adherence in the presence of CPU-heavy computations. Data collected from these trials are logged into CSV format and visualized using Python plots for comprehensive analysis. Our findings indicate that while C is suitable for soft real-time systems with relatively predictable loads, hard real-time performance requires OS-level scheduling control, such as the integration of real-time patches or RTOS environments. These experiments not only reinforce C's role in system-critical programming but also highlight the need for modern systems to balance determinism with performance under load.}, keywords = {C programming, deadline violation, interrupt handling, real-time systems, task scheduling.}, month = {June}, }
