C++STLvectorassign⽤法
vector::assign //⽤来构造⼀个vector的函数，类似于copy函数
钢琴英语怎么说
void assign( size_type _Count, const Type& _Val);
//_Count指要构造的vector成员的个数， _Val指成员的数值，他的类型必须与vector类型⼀致！
template<class InputIterator>
void assign( InputIterator _First, InputIterator _Last );
不求甚解拼音//两个指针，分别指向复制开始和结束的地⽅!
EXAMPLE
// vector_assign.cpp
// compile with: /EHsc
#include <vector>

int main( )
{
using namespace std;
vector<int> v1, v2, v3;
vector<int>::iterator iter;
v1.push_back(10);
v1.push_back(20);
v1.push_back(30);

v1.push_back(50);
cout << "v1 = " ;
for (iter = v1.begin(); iter != v1.end(); iter++)
cout << *iter << " ";
cout << endl;
v2.assign(v1.begin(), v1.end());
cout << "v2 = ";
for (iter = v2.begin(); iter != v2.end(); iter++)
cout << *iter << " ";
cout << endl;
v3.assign(7, 4) ;
cout << "v3 = ";武汉大学招生简章
for (iter = v3.begin(); iter != v3.end(); iter++)
cout << *iter << " ";
cout << endl;雅思机考模拟
}
输出结果为：
v1 = 10 20 30 40 50
v2 = 10 20 30 40 50
v3 = 4 4 4 4 4 4 4
