I am VERY new to C#/programming and as a learning exercise completed an online challenge to change text to lowercase. The challenge specified it must 'print to stdout' yet I completed the challenge by using Console.Writeline
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Lowercase
{
class Program
{
static void Main(string[] args)
{
using ( StreamReader reader = new StreamReader("TextFile1.txt"))
{
while (!reader.EndOfStream)
{
string line = reader.ReadLine();
Console.WriteLine(line.ToLower());
}
Console.ReadLine();
}
}
}
}
Is stdout just another name for outputting to console (submissions could be in many different languages) or did the online code submission just not check the output properly. I have googled 'stdout c#' but don't fully understand the results.
In languages like C and C++, there is a global variable with the name stdout, which is a pointer to the standard output stream. Thus, stdout has become a commonly used abbreviation for "standard output stream" even outside the context of the C language.
Now, what does C# do? Let's have a look at the documentation of Console.WriteLine (emphasis mine):
Writes the specified string value, followed by the current line terminator, to the standard output stream.
So, yes, Console.WriteLine does exactly what you need to do. If you need a direct reference to the standard output stream (Hint: you usually don't), you can use the Console.Out property.
