Thread: While loop trouble

I am writing a simple C program using a while loop to enter numbers to a file. I'm very new to this so please don't say it's obvious.

Code:

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

int main()
{
	int neilsdata[5];
	int val, pos;
	FILE *neilfile;
	int cont = 1;
	char contch;

	// open file
	if( ( neilfile = fopen( "vals", "wb" ) ) == NULL )
	{
		printf("Couldn't create file\n");
		exit( -1 );
	}

	// write data to file
	while ( cont==1 )
	{
		printf("Enter a value\n");
		scanf("%d", &val);

		fwrite( &val, sizeof val, 10, neilfile );

		printf("Do you want another value\n");
		scanf("%d", &contch);
		if( contch == "y" )
			cont = 1;
		else
			cont = 0;
	}

	fclose( neilfile );
	

	// read in same file
	// open file
	if( ( neilfile = fopen( "vals", "rb" ) ) == NULL )
	{
		printf("Couldn't open file\n");
		exit( -1 );
	}

	fread( &val, sizeof val, 1, neilfile );
	while( !feof( neilfile ) )
	{
		printf (&val, "\n");
		fread( &val, sizeof val, 1, neilfile );
	}

	fclose( neilfile );

	getch();
	getch();

}

After taking one value and entering y/n it just throws a whole line of unhelpful characters and ends there. Something with the loop, or the scan command?

Look at the %d scanf format and the type of the variable contch.
