编写程序处理vector<int>对象的元素：将每个奇数值元素用该值的两倍替换。

int main()

{

vector<int> ivec;

ivec.push_back(1);             //赋值

ivec.push_back(2);

ivec.push_back(3);

ivec.push_back(4);

ivec.push_back(5);

ivec.push_back(6);

for (vector<int>::iterator it = ivec.begin(); it != ivec.end(); ++it)

{

*it = (*it%2 == 1) ? (*it * 2) : (*it);

cout << *it;

}

return 0;

}
