vector<int>::iterator result = find( L.begin( ), L.end( ), 3 ); //查找3 if ( result == L.end( ) ) //没找到 cout << "No" << endl; else //找到 cout << "Yes" << endl; } 记着要包含algorithm这一头文件,其定义了find这一函数。 资料参考:https://www.coonote.com/cplusplu...
First, this program imports all the necessary header files such as <iostream> and <vector>. After this, a vector is declared with few elements. On executing the code, the size of the vector is printed using the size() function. Example #2 CPP program that uses size() function in vector...

该函数返回一个迭代器,指向范围[first1,last1)中最后一次出现的[first2,last2)的第一个元素。如果未找到序列,则函数返回last1值。示例1#include <iostream> #include <algorithm> #include <vector> bool newfunction (int m, int n) { return (m==n); } int main () { int newints[] = {1,2,...
