Input/Output

I am having a problem with input/output. I have created a text file called input.txt and want to move this to output.txt
I have been able to move a single character over with %c but when I have tried to use %s it doesn't appear to work.

This is the code I have used:

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>

void main (void)
{
char e[30];
char temp_char;
int counter;

FILE *f_input;
FILE *f_output;

for(counter=0; counter<200; counter++)

if ((f_input = fopen("input.txt","r"))==NULL)
{
printf("Cannot open file\n");
exit(1);
}

fscanf(f_input,"%c", &temp_char[counter]);
if ((f_output = fopen("output.txt","w"))==NULL)
{
printf("Cannot open file for writing\n");
exit(1);
}

fprintf(f_output,"The input file contained the following: %c \n",temp_char);

fclose(f_input);
fclose(f_output);

getch();
}

Can anyone help, thanks if you can.

try this

Code:

---

int main()
{
    int ch;
    FILE *f_input, *f_output;

    if ((f_input = fopen("input.txt","r"))==NULL)
    {
          printf("Cannot open file\n");
          exit(1);
    }
 
    if ((f_output = fopen("output.txt","w"))==NULL)
    {
          printf("Cannot open file for writing\n");
          exit(1);
    } 

   

    while((ch = fgetc(f_input)) != EOF)
          fputc(ch, f_output);

    fclose(f_input);
    fclose(f_output);
    return 0;
}

---

look up fgetc, fputc and EOF in your documentation

Thanks for that - It is now working.

Out of interest, if I wished to transfer message over but this time backwards will I be ok to use a'For' loop?

Of course.

You just read the message from the end to the start and print it out on the screen.
