在C++98标准中,基于范围的for循环(range-based for loop)是不被支持的。这种循环结构是C++11及以后版本中引入的,用于简化对容器(如std::vector、std::list等)或数组的遍历。基于范围的for循环自动处理容器的开始和结束迭代器,使得代码更加简洁易读。 替代方案以在C++98中实现类似功能 在C++98中,你可以使用传统的...

// sample usage of the range-based for loop on IntVector int main() { IntVector v; for ( int i = 0; i < 100; i++ ) { v.set( i , i ); } for ( int i : v ) { cout << i << endl; } }One thing to notice about this code is that it does not allow modification ...
When used with a (non-const) object that has copy-on-write semantics, the range-basedforloop may trigger a deep copy by (implicitly) calling the non-constbegin()member function. If that is undesirable (for instance because the loop is not actually modifying the object), it can be avoided...
Using light to manipulate fluids has been a long-sought-after goal for lab-on-a-chip applications to address the size mismatch between bulky external fluid controllers and microfluidic devices. Yet, this goal has remained elusive due to the complexity of

Let’s take a closer look at common ways aforloop can causeList Index Out of Rangeand how to either avoid it completely or gracefully handle this error when it crops up. What causes the “List Index Out of Range” error? As Python uses zero-based indexing, when you try to access an...
