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"); }

void (*states[4])() = { state_init, state_load, state_execute, state_exit };

// Your logic here
void run_state_sequence(int start) {
    // Implement using function pointer array
    for( int i = 0; i < 3; ++i ) {
        states[ ( start + i ) % 4 ]( );
        printf( "\n" );
    }
}

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