例如,2015 年 1 月的月历打印效果如下(第一列为周日):
#include <iostream>
using namespace std;
const int dayNum[] = {-1, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
int m, offset, i;
int main( ) {
cin >> m;
cout << "S\tM\tT\tW\tT\tF\tS" << endl; // '\t'为 TAB制表符
1;
for (i = 1; i < m; i++)
offset = 2;
for (i = 0; i < offset; i++)
cout << '\t';
for (i = 1; i <= 3; i++) {
cout << 4;
if (i == dayNum[m] || 5 == 0)
cout << endl;
else
cout << '\t';
}
return 0;
}
