vector基本操作|随机生成乱序字符串

#include <iostream> #include <string> #include <vector> using namespace std; int main() { string tmp1,tmp2; tmp1="rusher;lewjan;bill;stan;yx;"; tmp2="abcc"; vector<string>list; list.push_back(tmp1); list.push_back(tmp2); for (unsigned int i=0;i<list.size();i++) { cout<<list[i]<<endl; } return 0; }

输出：

VirtualBox:~/code/vector$ ./myvect
rusher;lewjan;bill;stan;yx;
abcc

给定一些字符，随机挑选一些

#include <iostream> #include <time.h> #include <stdlib.h> using std::cout; const int SIZE_CHAR = 32; //生成32 + 1位C Style字符串 const char CCH[] = "_0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_"; int main() { srand((unsigned)time(NULL)); char ch[SIZE_CHAR + 1] = {0}; for (int i = 0; i < SIZE_CHAR; ++i) { int x = rand()%sizeof(CCH); ch[i] = CCH[x]; } cout <<ch <<"/n"; return 0; }

每次输出长度不一，分布较均匀
