friends before any thing apologizes for English I am using translator because only of the brasil and I don't know how to write.
my problem is the following I have to create a program that reads a text and it prints the same text to the I thwart oh this that I did

  1. #include <stdio.h>
  2. #include <stdlib.h>
  3. #include <conio.h>

1) learn to properly format your code to make it easier to read and understand.

2) The for loop on line 80 is not formed correcly
