c++中vector的find函数用法 vector的find函数用于在vector容器中查找特定元素。它能帮助快速定位元素位置，提高编程效率。使用find函数需包含algorithm头文件。find函数返回一个迭代器指向找到的元素。若未找到元素，则返回vector.end()迭代器。其函数原型为：iterator find (iterator first, iterator last, const T val);...
my_vector.push_back(my_value); std::vector<struct value_t>::iterator it = my_vector.end(); it = std::find_if(my_vector.begin(), my_vector.end(), vector_finder(13)); if (it == my_vector.end()) printf("not found\n"); else printf("found value.a:%d value.b:%d\n", it...
int* find(const <vector>& vec, int value) 如果vector中存放的是string,或者任意类型的对象呢?有没有通用的,泛化的find(),对存放不同类型的接口一样?function template提供了一种解法: 可以查找任意类型元素的泛化find() 注意: 1,第二个find()的第二参数为elemType&类型,其实准确的应该为const elemType&类型...
//variable to store the vector size int s = vtr.size() ; //print the vector size cout <<"The vector size is: " << s ; return 0; } Output: In this program, a vector is declared with string elements, unlike the above programs. But, the size() function prints the size of the...
std::vector<int> vec = {1, 2, 3, 4, 5};// 使用 find 函数查找值为 3 的元素 std::vector<int>::iterator result = std::find(vec.begin(, vec.end(, 3);if (result != vec.end()std::cout << "元素 3 在容器中找到了！" << std::endl;} else std::cout << "元素 3 在容器...
it = std::find_if(my_vector.begin(), my_vector.end(),vector_finder(13));if(it == my_vector.end())printf("not found\n");elseprintf("found value.a:%d value.b:%d\n", it->a, it->b);return0; } 最后来一个实战中用到的。vector<string>中的string的首字母依照字母表进行排序: ...

We can also use the standard algorithm std::find_if, which accepts a predicate. This is the recommended approach if the search needs to satisfy certain conditions. For example, finding the index of the first string starting with some character in a vector of strings. 1 2 3 4 5 6 7 8...
