my_map.erase("key"); ``` 其中,"key"是要删除的键。如果"key"不存在于`my_map`中,那么`erase`方法不会有任何作用。 此外,`erase`方法还可以接受一个迭代器作为参数,删除迭代器指向的元素,并返回下一个元素的迭代器。例如: ```cpp auto it = my_map.find(2); if (it != my_map.end()) it...
erase(const key); 按范围擦除:它将两个迭代器作为参数,并擦除介于两者之间的所有键和值(包括起始迭代器和结束迭代器)。 用法: unordered_map.erase(const iteratorStart, const iteratorEnd); // CPP program to demonstrate implementation of // erase function in unordered_map. #include <bits/stdc++....
1 打开Arcmap,我这里又点point、线line、面polygon、面polygonB四个图层。在点point、线line、面polygon分别有图形显示如下图：2 然后在面polygonB中画一个擦除层，这里就画一个长方形作为参照。3 点击ArcToolbox，打开ArcToolbox工具箱，找到下面的erase工具。4 双击erase，打开erase对话框。在对话框中选择输入图...
Each element erasure takes time proportional to the logarithm of the number of elements in the controlled sequence. Example // cliext_map_erase.cpp // compile with: /clr #include <cliext/map> typedef cliext::map<wchar_t, int> Mymap; int main() { cliext::map<wchar_t, int> c1; c1....
Different ways to delete elements in std::map (erase() and clear()) 本文处理的是地图的删除部分。 使用erase() :erase() 用于擦除参数中提到的 map 中的对,无论是它的位置、它的值还是一个数字范围。 erase(key) :使用其参数中提到的键擦除键值对。删除后重新排序地图。它返回删除的条目数。如果删除...
