C++ provides the functionality to find an element in the given range of elements in a vector. This is done by the find() function which basically returns an iterator to the first element in the range of vector elements [first, last) on comparing the elements equals to the val (value to ...

While learning a new concept in a programming language, you have to understand the same basic syntax. So, let us see the syntax of the size() function in vector. vec.size() Here, vec is the name of the vector Parameters of the function: ...
一种解法是function overloading。对vector和array分别编写find()。除此有没有能够支持这两种容器的通用find()呢? 把大问题切割成难度较小的子问题,逐一求解,是一种思路。分隔成的两个问题: 1,vector传入find()的是元素,而不用指明该vector。 2,array传入find()的是元素,而不用指明该array。
