清空栈 和清空queue类似,stack没有clear()函数,但是可以通过多种办法来实现。 代码语言:c++ AI代码解释 //方法一:只要栈不为空就一直弹出,直到为空 while(!stk.empty())stk.pop(); //方法二:直接赋值一个新的stack,默认为空栈 stk = stack<int>(); 交换栈 语法:stk1.swap(stk2),返回值为void(),复...

Afterward, we employ a simpleforloop to clear the elements in thenumsarray. We iterate through the array, setting each element to the value0. Finally, we print the modified contents of thenumsarray in the same visually formatted manner. All elements in the array have been successfully changed...
