急!!!!!高手帮助
这个程序应该怎么改#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main()
{
void TodayNeedToDo();
void RememberDayManage();
void Wordpad();
void Monthlycalendar();
int inputnum;
printf("*********<<<<<Calendar>>>>***********\n");
printf("Please select one of the following program:\n");
printf("1: <TodayNeedToDo>\n");
printf("2: <RememberDay Manage>\n");
printf("3: <Wordpad>\n");
printf("4: <Monthly calendar>\n");
printf("5: <exit this program>\n");
printf("****************************************************\n");
printf("-----------------------------------------------------n");
printf("You can select 1-5\n");
scanf("%d",&inputnum);
/*not exit program untill input 4*/

case 1: TodayNeedToDo();break;
