C++ vector容器中常见的三种遍历方式

Posted 2022-01-07 唐火

1.迭代器

    for (std::vector<int>::iterator it = vecTest.begin(); it != vecTest.end(); ++it)
    
    	tempNum = *it;
    

2.C++11 新增关键字auto

 for (auto it : vecTest)
    
    	tempNum = it;
    

3.对C念念不舍的童鞋们习惯的数组写法

  for (size_t i = 0; i < maxCount; i++)
    
    	tempNum = vecTest[i];
