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_init(std::vector<BoxInfo> &bboxs) 14 { 15 BoxInfo u_temp; 16 for(int i = 0; i < 10; i++) 17 { 18 u_temp.score = ...
cout << endl;return0; }#include<iostream>#include<string>#include<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;...
int sum(void* ptr) { vector num(*(vector *)ptr); for (int x : num) { cout << x << endl...
