Thread: I want to convert this C program to C#

This is not a free coding factory. Provide info about your attempt, and people will be more likely to help.

Incidentally, getch() is not standard C either - so you're not supposed to use it. It's a philosophical argument whether it's better to use system("pause") (which has implementation-defined behaviour, so is not guaranteed to do anything in particular), or getch() (which is not standard, so is not guaranteed to be supported by your compiler/library). There is plenty of information available about alternative approaches, some of which even make use of standard functions for which behaviour is well specified.

Sorry bout that I guess I should say why isn't this code working or I can't get it to work it doesn't have any errors in it. It just doesn't work here's my code that I have.

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Chapter5Problem6
{
    class Program
    {
        static void Main(string[] args)
        {
            string ch;
            int num_chars = 0;
            int num_lines = 0;

            Console.Write("\nThis program counts the number of characters");
            Console.Write("\nyou enter on each input line and outputs the");
            Console.Write("\ntotal number of characters and lines entered.");
            Console.Write("\nTerminate each line with Enter. Terminate the");
            Console.Write("\nprogram by pressing Enter [Ctrl]+Z, and Enter.\n\n");

            while ((ch = Console.ReadLine()) != null)
            {
                num_lines++;
                do
                {
                    num_chars++;
                } while ((ch = Console.ReadLine()) != "\n");
            }

            Console.Write("\nYou entered {0} characters and {1} lines.\n\n", num_chars, num_lines);


            Console.ReadKey();
        }
    }
}

Sorry about the code not formatting right I couldn't fix it I hope you guys can read it

You might want to start by reading the documentation for Console.ReadLine(), rather than assuming it behaves like C's getchar() function. It does not include the end of line markers in the string it returns, and it does not read one character at a time. Your code assumes it does both. If the first call of Console.ReadLine() doesn't return null, the inner loop will run forever.

Aww.... cmon. YOU actually need to apply effort.

You're essentially claiming you're incapable of converting code that uses a function that reads one character at a time (getchar()) so it uses a function that reads a line at a time and discards newlines (Console.GetLine()).

If that reflects your ability, it's a wonder you know how to turn a computer on. If it reflects your effort (most likely, as most people have the ability but need to TRY) you and the world would be better off if you abandoned software and got a job flipping burgers (although it does take effort and technique to flip burgers, so maybe you need to find something less demanding to do).

Well grumpy motivated me to figure this out so I came up with this its closer but, I'm still not there

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Chapter5Problem6
{
    class Program
    {
        static void Main()
        {
            int ch;
            int num_chars = 0;
            int num_lines = 0;


            while ((ch = Console.Read()) != 0 )
            {
                num_lines++;
                do
                {
                    num_chars++;
                }while((ch = Console.Read()) != '\n');
            }

            Console.Write("\nYou entered {0} characters and {1} lines.\n\n", num_chars, num_lines);
            Console.ReadKey();

        }
    }
}

In general I recommend against blindly porting code from one language to another, at least until you've achieved mastery in both languages. It tends to produce code that is similar in quality to written text, translated to Chinese and then back to English.

Don't think about "what's the C# equivalent to X", think "how do I accomplish Y in C#". The C# code may look little to nothing like the C code, and that's fine. The goal isn't to solve the problem in exactly the same manner.

For the record, this post translated into Chinese then back to English twice becomes:

Overall, I do not recommend blind portable code from one language to another, at least until you have reached mastered both languages. It tends to produce code that is similar in quality written text, translated into Chinese and then back to English.

Do not think, "What is the equivalent to X in C#", that "how I implement in C# Y." C# code might look almost nothing like C code, which is good. The purpose is not to solve the problem in exactly the same way.
