编写一个程序，统计data.txt文件的行数，并将所有行前加上行号后写到data1.txt文件中。算法提示：行与行之间以回车符分隔，而getline()函数以回车符作为终止符。因此，可以采用getline()函数读取每一行，再用一个变量i计算行数。 （1）实现源代码  #include #include #include #include  using

For example, we often encounter such as the pointer as a variable when the empty is an exception, we will use the ASSERT () or write a prompt user's exception handling, this time we will use similar to return exit () This kind of process, this

Traditional collection operationsIn the absence of generics, we use Ayylist to manipulate the collection, which can hold any type of data, but eventually it is converted to object storage, and if the incoming data is a value type, you need to
