私はテスト目的のためだけにプログラムを作成しました。キーボードのキー 'p' を押したままにすると、2012 年 1 月 1 日から毎日こぼれ落ち、2013 年まで続くはずで、2013 年 1 月 32 日になっても続きます。これは修正方法がわからないエラーです。この問題を数時間修正しようとしましたが、何もうまく機能していないようです.. (2013 年 2 月 1 日 31 日以降1月）

ここに私のコードがあります:

#include <stdio.h>
#include <stdlib.h>


int month[] = {0,31,28,31,30,31,30,31,31,30,31,30,31};

int day = 0;
int year = 2012;

char *months[]=
{
    " ",
    " January ",
    " February ",
    " March ",
    " April ",
    " May ",
    " June ",
    " July ",
    " August ",
    " September ",
    " October ",
    " November ",
    " December "
};


int x = 1; //skip the blank element 0, get to January (element 1)

int main()
{

while(1)
{
    char ch;
    ch = getch(); //in_char();

    if(ch == 'p')
    {
        day++;


        if(day == month[x]+1)
        {
            day = 1; //day is equal to the first day of the new month
            month[x]++; //month data increments
            months[x]++; //month display increments
            x++; //element of month array increments to get the data of the next month


            if(year % 4 == 0) //leapyear
            {
                month[2] = 29;
            }
            else
            {
                month[2] = 28;
            }


            if(x == 13) //if 12 months have passed
            {
                year++; //year increments
                day = 1; //initialize day to be day 1 of the next year
                x = 1; //go back to the 'January' element in the array

                if(day == month[x]) //if day is equal to the first month (January) 31 days
                {
                    day = 1;
                    month[x]++; //month data increments
                    months[x]++; //month display increments
                }
            }
        }
        if(year == 9999)
        {
            year = 1;
        }


        printf("%i%s%04i\n",day,months[x],year);
    }
}


return 0;
}

問題はここにあります：

    if(day == month[x]+1)
    {
        day = 1; // reset date...OKAY
        month[x]++; // NOT OKAY

そうmonth[x]++することで、その月に許可される日数が増えます。代わりに、日と年で行ったのと同じように、月を追跡する変数を保持する必要があります..
