pair<int,double>p1; p1 = make_pair(1, 1.2); 1. 2. (2)变量间赋值: pair<int,double>p1(1, 1.2); pair<int,double>p2 = p1; 1. 2. 可以用cmp数组改; 代码: #include<iostream>#include<cstdio>#include<cstring>#include<cmath>#include<algorithm>#define mem(x,y) memset(x,y,sizeof(...

1.1、pair类型的定义和初始化 pair类型是在有文件utility中定义的,pair类型包含了两个数据值,通常有以下的一些定义和初始化的一些方法: pair<T1, T2> p; pair<T1, T2> p(v1, v2); make_pair(v1, v2) 上述第一种方法是定义了一个空的pair对象p,第二种方法是定义了包含初始值为v1和v2的pair对象p。...
,也就是一个Pair,Key是"idcountry",而Value是"中国"。例子二:1、定义一个CMAP,向这个CMAP中增加数据项(键-值对)。CMap<CString, LPCTSTR, CString, LPCTSTR>m_ItemMap;CString strKey = _T(""), str = _T("");int i;for(i = 0; i < 5; i++) { strKey.Format("%d", i); //这个是键...
