Erase() function to remove a range of elements from a vectorWe can also remove a range of elements by passing first and last position in the erase function. Syntax: For removing a range of elements: vector_name.erase(iterator first, iterator last);Example: vector1={10, 20, 30, 40, ...
STL中remove()只是将待删除元素之后的元素移动到vector的前端,而不是删除。若要真正移除,需要搭配使用erase()。 1.、erase() causes large amount of copies while remove() just does a logical delete and leaves vector unchanged by moving element around. 2、If you need to remove multiple elements, remo...
Example 1: Delete Negative Elements from VectorIn Example 1, I’ll explain how to remove negative values from a vector object in R.For this example, we first have to create an example vector:vec <- c(1, 5, - 3, 2, 2, - 5, 7) # Create example vector vec # Print example ...

vector<int>::iterator it; cout << "原始序列" << endl; for (it = ar.begin(); it != ar.end(); it++) cout << *it << "\t"; //\t 的意思是 横向跳到下一制表符位置 cout <<"\n"<< endl; //\n 的意思是回车换行 // remove all elements from ar that match 10 ...
