Read Write File (handling) in c++ and c# Character by Character with Char 46
Shows how to read a file with #characters. How to change #char to #string. How to #read a file letter by letter in c plus plus and c sharp.
c++ code:
#include ＜iostream＞ //for cout
#include ＜fstream＞ // for ofstream/ifstream
#include ＜string＞ //for ＜＜ and getline
int main()
{
std::fstream input_file("test.txt");
//std::ifstream input_file("test.txt");
std::ofstream output_file("test.txt.out");
char line;
//while (input_file ＞＞ std::skipws ＞＞ line)
////for (;input_file ＞＞ std::noskipws ＞＞ line;)
//{
// std::cout ＜＜ line ＜＜ std::endl;
// output_file ＜＜ line ＜＜ std::endl;
// //std::cout ＜＜ std::string(1, line)＜＜std::endl;
// //output_file ＜＜ std::string(1, line)＜＜std::endl;
//}
for (;input_file.get(line);)
{
std::cout ＜＜ line ＜＜ std::endl;
output_file ＜＜ line ＜＜ std::endl;
}
std::cin.get();
return 0;
}
c# code:
using System;
using System.Collections.Generic;//for string
using System.IO;//to use StreamReader
namespace lec2csharp
{
class Program
{
static void Main(string[] args)
{
//StreamReader input_file = new StreamReader("test.txt");
StreamWriter output_file = new StreamWriter("test.txt.out");
//for (; !input_file.EndOfStream;)
//{
// char line = (char)input_file.Read();
// //Console.WriteLine(line);
// //output_file.WriteLine(line);
// Console.WriteLine(Char.ToString(line));
// output_file.WriteLine(Char.ToString(line));
//}
string input_file = File.ReadAllText("test.txt");
foreach (Char line in input_file)
{
Console.WriteLine(line);
output_file.WriteLine(line);
}
Console.ReadLine();
}
