1. Usingstd::erasefunction One way to erase elements from a vector in C++ is to use theerase()function from thestd::vectorclass. This function removes an element or a range of elements from a vector, and returns an iterator pointing to the element following the last removed element. The...
对于vector一般不要用erase(),因为很多情况下他要和<algorithm>中的remove()一块用！erase（）的使用会使迭代器失效如果删除的不是最后面的元素的话。你的程序中if(*iter%2==0) ivec.erase(iter); 可以换成：（记着加头文件<algorithm>）if (*iter%2 == 0)ivec.erase(remove(ivec.begin(...
