File Handling -Read write and edit a file
Hi guys im trying to get a program to read a file and copy its contents to another file so far I seem to be having a problem.
The file is only writing one letter, "X" in this case
Im just wondering what my problem is here?
the file im testing it on is just a massive text document, so there dhould be more than one letter comming out
Code:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
int main ( int argc, char *argv[] )
{
if ( argc != 2 )
{
printf( "usage: %s filename", argv[0] );
}
else
{
FILE *file = fopen( argv[1], "r" );
if ( file == 0 )
{
printf( "Could not open file\n" );
}
else
{
int x;
while ( ( x = fgetc( file ) ) != EOF )
{
FILE *outf;
//if (isspace(x)&&isspace(x-1)
//remove space
//else
outf = fopen("test.txt","w");
fprintf(outf,"%c");
fclose(outf);
}
}
fclose( file );
}
}
Eventually im going to use this program to tidy up a text document with float values, that sounds confusing as I type it, but its just a text file with numeric data on it but its very messed up as it looks something like this
Code:
121.2 12.12 121.21 1.212
1.12 121 121 1 1.212 12.12 121.2 12
ect....
What I want to do is tidy it up so that there is only one space between each value and hopefully start a new line after every 10 numbers.
