Question

请写一个程序 要求在控制台输入3个整数m,d,x, m、d代表M月d日并且是符合日期输入要求的，输出在m月d日后的第X天是几月几号，假设每一年的2月都是28天。月和日之间用空格隔开

例如：输入 2 28 1 输出3 1

Answer 1

#include "stdafx.h"

#include <iostream>

#include <time.h>

#include <ctime>

using namespace std;

int main()

{

tm time1;

int n,m, monthday[12] = {31,28,31,30,31,30,31,31,30,31,30,31};

cin >> time1.tm_mon >> time1.tm_mday >> n;

cout << "输入的日期是："<<time1.tm_mon << "月" << time1.tm_mday << "日" << endl;

m = n;

if (n >= 365)

n = n - 365;

while (1)

{

if (time1.tm_mday + n <= monthday[time1.tm_mon - 1])

{

time1.tm_mday = time1.tm_mday + n;

break;

}

else

{

time1.tm_mday = time1.tm_mday + n - monthday[time1.tm_mon - 1];

time1.tm_mon++;

n = 0;

}

}

cout <<m<< "天之后日期"<<time1.tm_mon << "月" << time1.tm_mday << "日" << endl;

system("pause");

    return 0;

}
