C++之for循环

>>>>>

记录几种常用for循环

// 循环
for(变量类型 变量名称:数组)
    循环内容;
for(auto 变量名称:数组)
    循环内容;

int studentid[] { 10001, 10002, 10003, 10004, 10005 };
for (int value: studentid)
    std::cout << value << std::endl;// 注意：value就是值，不是下标！

for (auto value: studentid)
    std::cout << value << std::endl;

for ( int i = 0; i < 15; i++)
	std::cout << i << std::endl;// i是下标

// 循环的嵌套
int studentId[5][5];
{
    [
        {1, 2, 3, 4, 5},
        {1, 2, 3, 4, 5},
        {1, 2, 3, 4, 5}
    ]
}
for ( int i = 0; i < 3; i++)
    let count = 0;
	for (auto value: studentId[i])
    {
        count++;
        std::cout << i + 1 << "班第" << count << "同学的学号是：" << value << std::endl;
    }
