Stroustrup 5.9，练习7 [英] Stroustrup 5.9, exercise 7
问题描述
/ * Stroustrup：5.9运动7
声明：
定义一个名为sof months o fyear和天数的表格。 >每月
。写出那张桌子。这样做两次：
1.）使用ar数组的char表示月份名称和一系列数字
表示天数。
2.）使用一组结构。每个结构都有
月的名称
及其相应的天数。
现在，我只尝试了（1） 。
* /
#include< iostream>
int main（）
{
const int months = 12;
int i = 0;
const char * ArrOfMonths [] = {" JAN" ，FEB，MAR，APR，MAY，
JUN，
" JUL"，" AUG" ;SEP，OCT，NOV，DEC; };
const int ArrOfDays [] = {31,28,31,30,31,30,31,31,30,31,30，
31};
std :: cout<< \tMONTH \ tDAYS \ n;;
const char ** pmonths = ArrOfMonths;
const int * pdays = ArrOfDays [0] ;
for（int i = 0; * pmonths！=''\'''|| * pdays！=''\ 0''; ++ i）
{
std :: cout<< " \t" << * pmonths
<< " \t" << * pdays
<< std :: endl;
++ pmonths;
++ pdays;
}
返回0;
