问题遇到的现象和发生背景
两个线程执行i++100次,结果不是不一定吗?为什么我这个代码,一直是200?哪里写错了,求指导
问题相关代码,请勿粘贴截图
void thread01(int* num)
{
for (int i = 0; i < 100; i++)
{
(*num)++;
cout <<"thread01:-----"<< *num << endl;
Sleep(100);
}
}
void thread02(int* num)
{
for (int i = 0; i < 100; i++)
{
(*num)++;
cout << "thread02:-----" << *num << endl;
Sleep(100);
}
}
static int count11 = 0;
int main()
{
thread task01(thread01, &count11); //带参数子线程
thread task02(thread02, &count11);
task01.join();
task02.join();
cout << "结果:"<< count11 << endl;
return 0;
}
