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 (* f_pointer[4])() = {state_init,state_load,state_execute,state_exit};
    for (int i = start ; i < start + 3 ; i ++)
    {
        if (i > 3)
        {
            
            int index = (i % 3) -1;
            //printf("%d\n" , index);
            f_pointer[index]();
            printf("\n");
        }
        else 
        {
            f_pointer[i]();
            printf("\n");

        }
        
       
    }

}

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