若要删除std::vector中的element,正规的方式该用find() generic algorithm,若find()找到了,会传回该iterator,若找不到,将传回vector.end()。这种写法远比用for loop干净很多。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : VectorFindAndErase.cpp 5 Compiler : Visual C++ 8.0...
basic question is how to check a vector of structs to find an element that meets a condition in one of the struct members - using std::find_if with a predicate: // find the first struct in a vector with a double // member <= a given value #include <iostream> // std::cout #inc...

This post will discuss how to find the index of the first occurrence of a given element in vector in C++. 1. Using std::find with std::distance function The simplest solution is to use the std::find algorithm defined in the <algorithm> header. The idea is to get the index using std...
This post will discuss how to insert an element at the beginning of a vector in C++. 1. Usingstd::vector::insertfunction The standard solution to insert an element to a vector is with thestd::vector::insertfunction. It takes an iterator to the position where the element needs to be inser...
