Hello World!
I am new at D, I'm making a sudoku solver in D, I wanted to add the option to read sudoku from a .txt file.

I am finding a bit confusing how to open, read and close files in D.

I am trying to mimic the C code:

FILE *f_in;
f_in=fopen("sudoku.txt");
if (f_in==NULL){
exit(1);
}
while(ch=fgetc() != EOF){
//convert char to int... put char in matrix...
}

could you help me? thank you, I appreciate it!

1) try to google "dlang read text file", most probably 1,2,3 link will help to u.
2) https://dlang.org/library/std/file/read_text.html
    string content = readText( fileName );

3) for matrix reading better to use byLine()
