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
/*
It looks like these functions are in some sort of array
And on the basis of input start, the contents of the array are printed
If state = [init, load, execute, exit]
func(state)
for(i = 0; i < state_index; i++)
state[i]
if(i == state_index) i = 0; 

*/
void run_state_sequence(int start) {
    // Implement using function pointer array
    void (*stateArray[4])(void) = {state_init, state_load, state_execute, state_exit};

    for(int i = 0; i < 3; i++)
    {
        stateArray[(start + i) % 4](); // Wrapping around using Modulo
        printf("\n");
    }
}

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