Answer 1

my rate is 15c/min

Answer 2

#include <stdio.h>

main() { int c; while ((c = getchar()) != EOF) { putchar(c); if (c == '\n') putchar(c); }

gcc -o prog prog.c

I haven't compiled this.  Debugging is up to you.  If this is an assignment, you should modify it to look good, and you should understand it.  Look up the calls.  You might have it actually open the input file, and write to an output file.  There may be compiler warnings.  Study them.

It gets a character at a time and writes that to stdout.  If the character is a newline, it emits a second newline. Why did i use an int instead of a char for the character?  Does it work with a char?  I'll give you a hint.  It should work on an x86, but not an Arm.  It's not much of a hint.

From the command line:

prog < file
