Hi, I have found one of your tutorials and have made substantial progress with my program. Here is the tutorial code
Code:
#include <stdio.h>
int main ( int argc, char *argv[] )
{
if ( argc != 2 ) /* argc should be 2 for correct execution */
{
/* We print argv[0] assuming it is the program name */
printf( "usage: %s filename", argv[0] );
}
else
{
// We assume argv[1] is a filename to open
FILE *file = fopen( argv[1], "r" );
/* fopen returns 0, the NULL pointer, on failure */
if ( file == 0 )
{
printf( "Could not open file\n" );
}
else
{
int x;
/* read one character at a time from file, stopping at EOF, which
indicates the end of the file. */
while ( ( x = fgetc( file ) ) != EOF )
{
printf( "%c", x );
}
}
fclose( file );
}
}
All i need to do now, is get a loop going so that it can read from a series of text files and not just one. I tried it by adding this:
Code:
#include <stdio.h>
int main ( int argc, char *argv[] )
{
int files;
int i;
printf("How many files to open? ");
scanf("%d",&files);
for(i = 0; files > 0; i = i + 1);
{
if ( argc != 2 ) /* argc should be 2 for correct execution */
{
/* We print argv[0] assuming it is the program name */
printf( "usage: %s filename", argv[0] );
}
else
{
// We assume argv[1] is a filename to open
FILE *file = fopen( argv[1], "r" );
/* fopen returns 0, the NULL pointer, on failure */
if ( file == 0 )
{
printf( "Could not open file\n" );
}
else
{
int x;
/* read one character at a time from file, stopping at EOF, which
indicates the end of the file. Note that the idiom of "assign
to a variable, check the value" used below works because
the assignment statement evaluates to the value assigned. */
while ( ( x = fgetc( file ) ) != EOF )
{
printf( "%c", x );
}
}
fclose( file );
files = files - 1;
}
}
}
But it doesnt work and it just keeps asking "How many files?". Please could someone help.
