State Machine Using Function Pointers

Code

#include <stdio.h>

void state_init()    { printf("Init"); }
void state_load()    { printf("Load"); }
void state_execute() { printf("Execute"); }
void state_exit()    { printf("Exit"); }

// Your logic here
void run_state_sequence(int start) {
    // Implement using function pointer array
    void (*func[4][3])() = {
    {&state_init, &state_load, &state_execute}, // Row 0
    {&state_load, &state_execute, &state_exit}, // Row 1
    {&state_execute, &state_exit, &state_init},     // Row 2
    {&state_exit, &state_init, &state_load}     // Row 2
};

    func[start][0](); 
    printf("\n"); 
    func[start][1](); 
    printf("\n");
    func[start][2](); 
    printf("\n");
    




}

int main() {
    int start;
    scanf("%d", &start);
    run_state_sequence(start);
    return 0;
}
