(vec); // 使用 begin 获取 vec 的开始迭代器 std::cout << *it << std::endl; // 打印第一个元素 int ia[] = { 0,1,2,3,4,5,6,7,8,9 }; // ia is an array of ten ints int* beg = begin(ia); // pointer to the first element in ia int* last = end(ia); // ...
相关知识点: 试题来源: 解析 解:\((array)l(x-y=20①)(x+y=10②)(array).,①+②,得2x=30,解得:x=15③,把③代入①,得y=5,所以原方程组的解为\((array)l(x=15)(y=5)(array).. 利用加减消元法解出方程组.反馈 收藏

值,当x<0时,它们对应的函数值互为相反数;当x≥0时,它们对应的函数值相等,我们称这样的两个函数互为相关函数.例如:一次函数y=x-1,它的相关函数为y=\left\{\begin{array}{l}-x+1({x<0})\\ x-1({x≥0})\end{array}\left\{\begin{array}{l}-x+1({x<0})\\ x-1({x≥0})\end{array...
