如果有一个文件aaa.txt,有若干行,不知道每行中含有几个整数,要编程输出每行的整数之和,该如何实现? 由于cin>>不能辨别空格与回车的差异,因此只能用getline的方式逐行读入数据到string变量中,但在string变量中分离若干个整数还是稍显吃力.一个好的方法是用string流: #include<iostream> #include<sstream> #include<fstream> using namespace std; int main

使用C#将字符串转化成流,将流转换成字符串,代码如下: using System.IO; using System.Text; namespace CSharpConvertString2Stream { class Program { static void Main( string[] args ) { string str = "Testing 1-2-3"; //convert string 2 stream byte[] array = Encoding.ASCII.GetB

static void Main( string[] args ) { string str = "Testing 1-2-3"; //convert string 2 stream byte[] array = Encoding.ASCII.GetBytes(str); MemoryStream stream = new MemoryStream(array); //convert stream 2 string StreamReader reader = new StreamRea
