Hello,

I am trying to finish up a group project but I am running into a small problem. I keep getting an error about fgetc not being callable. The purpose of my program is to count the number of characters in a file. Any bit of help is appreciated!

Here's my code:

import std.stdio;
import std.file;
import std.string;


void main()
{
	FILE *file;
	char ch;
	int charCount,wordCount,input;
	
	
	
	//File file = File("test.txt","w");
	 //input=fscanf(file, "%ch",&ch);
	
	 //file.writeln("hello");
	
	//string s = file.readln();
	
	file=fopen("test,txt","r");
	
	while(!file.eof())
	{
		/*string line = chomp(file.readln());
		wordCount++;
		writeln(wordCount);*/
		
		ch = getc(file);
		charCount++;
			
	}
	
	
	
	file.close();

		
	
	
}

Since you're using the C library stdio functions, you should import core.stdc.stdio

ok I added that in, but now its giving me this:

 function core.stdc.stdio.getc (shared(_IO_FILE)* stream) is not callable using argument types (File)

Am I just using getc the wrong way?

You're mixing Phobos' `File` object and C's FILE stream. You're passing the `File` to getc which expects FILE. Also, if there's no specific reason, you should prefer the Phobos' file (which doesn't work with getc from C, as it would require obtaining the C stream from Phobos object, which would not be the best idea).

Try something like this:

...
ch = getc(file.getFP);
...
