1. 非指针类型vector的初始化 对于非指针类型的vector可以使用赋值符号=、循环遍历push_back()、fill()函数进行初始化,代码如下: #include<iostream>#include<algorithm>#include<vector>using namespacestd;intmain(int,char**){vector<int> vec_int_a = {0,0,0,0,0};vector<int> vec_int_b;for(inti =...
1 #include <iostream> 2 #include <stdio.h> 3 #include <vector> 4 5 6 struct BoxInfo 7 { 8 int label; 9 float score; 10 }; 11 12 13 int bbox_...
vector<int> nums = {-2,1,-3}; void* ptr = &nums; sum(ptr);
<vector>#include<algorithm>usingnamespacestd;//指针可以当做迭代器//intmain(intargc,constchar*argv[]){inta[5] = {2,3,1,0,9};int*pos =find(a, a +5,1);//迭代器和数组中的地址在find里面可以等效cout << pos << endl;//比如说也可以使用数组的地址实现对容器的初始化cout << &a[2] ...
