Code for scheduling in C

• Define a struct for the task with fields like start time, end time, priority, etc.

• Create an array of tasks and sort them based on priority and start time

• Implement a scheduling algorithm like Round Robin or Priority Scheduling

• Use system calls like fork() and exec() to create and execute processes

• Implement synchronization mechanisms like semaphores or mutexes to avoid race conditions

Static, volatile, const are C keywords used to define properties of variables.

• Static: used to define a variable that retains its value between function calls

• Volatile: used to indicate that a variable's value may change unexpectedly, e.g. in an interrupt

• Const: used to define a variable whose value cannot be changed once initialized
