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 (*operation[4])()={state_init,state_load,state_execute,state_exit};
    int i,count=0;
    for(i=start;count<3;i++){
       operation[i]();
       printf("\n");
       count++;
       if(i==3){
        i=-1;
       }
    }
    
}

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