所以，我想创建一个从数组中选取简单字符串的程序，对我来说听起来很简单，但后来我遇到了问题。这是我写的：
int pickjob;
string jobs[] = {Police Officer, Fireman, Vet, Doctor, Nurse, Chemist, Waiter};
job1 = jobs[rand()%7];
job2 = jobs[rand()%7];
job3 = jobs[rand()%7];
cout << "Here i found some jobs for you, check them out\n1." << job1 << "\n2." << job2 << "\n3." << job3 << "\nGo Head and pick one out" << endl;
cin >> pickjob;
//Rest of code is below, i'll put it in if you need it ;)
但我的问题是，每次我运行该程序时，每次都会出现相同的工作（我是C ++的一名业余爱好者，所以如果我听起来很愚蠢，请原谅我），那么我如何创建一个程序，每次打印出不同的工作数组。
