C++ 标准模板类详解

// delete first and second elements
data.erase(data.begin(), data.begin() + 2);

// insert [old.begin + 1, old.end) in the front of data
data.insert(data.begin(), old.begin() + 1, old.end());
// 此时，超尾元素显得十分方便
// 在末尾紧挨着插入元素
data.insert(data.end(), old.begin() + 1, old.end());

// 代替for循环
for(auto iter = data.begin(); iter != data.end(); iter++) {
    showData(*iter);
}
// replace for with for_each
// 注意此处的函数showData不能修改data的值。
for_each(data.begin(), data.end(), showData);

// usage 1
sort(data.begin(), data.end());
// usage 2
bool compare(const structData& a, const structData& b) {
    if(a.index == b.index) {
        return a.data < b.data;
    }
    return a.index < b.index;
}
// sort with index from little to big, if index is equal, sort with data.
sort(data.begin(), data.end(), compare);
