C + +-CallBack

This is the lab building on the previous callback debug example, I did not submit the validation, but running on-premises without any problems, and no warning:

#include <stdio.h> #define MAX 3typedef Int (*alarm) (int type); alarm Alarm_list[max];int index = 0;void Register_ala RM (alarm a); int hit_alarm (int index), void Register_alarm (alarm a) {    alarm_list[index++] = A;} int hit_alarm (int index) {    if (Index < 0 | | index >= MAX)        return 1;    (*alarm_list[index]) (index);    return 0;} int alarm1 (int type) {    printf ("one:%d\n", type);    return 0;} int alarm2 (int type) {    printf ("two:%d\n", type);    return 0;} int alarm3 (int type) {    printf ("three:%d\n", type);    return 0;} int main{    register_alarm (ALARM1);    Register_alarm (ALARM2);    Register_alarm (ALARM3);    Hit_alarm (0);    Hit_alarm (1);    Hit_alarm (2);    return 0;}

Write another example of implementing a callback:

#include <stdio.h>typedef int (*__callback__) (void* type_param), void Func_register (__callback__ func, void* param), void Func_register (__callback__ func, void* param) {    (*func) (param);} Custom Function int My_func (void* param) {    printf ("Param is%d\n", (int*) param);    return 0;} int main{    //Custom function is invoked as a function parameter    func_register (My_func, (void*) 5);    return 0;}
