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...

用C++的stl库,相信大家都有用vector的经历,毕竟vector支持直接下标方式取数据的确方便很多。 但是vector默认是不提供find方法的,所以我们在查找的时候,通常这样写代码: vector<int>vec; for(unsignedinti=0;i<vec.size();++i) { if(vec[i]==xxx)
#include <vector> #include <iomanip> usingnamespacestd; voidprint(inta[],intlen) { for(inti=0;i<len;i++) { cout<<setw(2)<<a[i]<<" "; } cout<<endl; } intmain() { inta[]={1,2,3,3,5,6,6,3}; intalen=sizeof(a)/sizeof(int); ...
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,...
