hello guys,
here is another problem on filing. it creates the intended files and it is saving as well. but the problem is the numbers become invisible this time in those files. it is showing . . . (dots) instead of even numbers or odd numbers. Anyone has got any idea why it is showing like that? here is the log
#include<stdio.h>
main()
{
FILE *f1,*f2,*f3;
int number,i;
printf("contents of DATA file \n\n");
f1=fopen("DATA","w");/*create data file*/
for (i=1;i<=30;i++)
{
scanf("%d",&number);
if (number==-1)break;
putw(number,f1);
}
fclose(f1);
f1=fopen("DATA","r");
f2=fopen("ODD","w");
f3=fopen("EVEN","w");
while ((number=getw(f1))!=EOF)/*Read from DATA file*/
{
if(number%2==0)
putw(number,f3);/*"write a EVEN file"*/
else
putw(number,f2);/*"write a ODD file"*/
}
fclose(f1);
fclose(f2);
fclose(f3);
f2=fopen("ODD","r");
f3=fopen("EVEN","r");
printf("\n\n contents of ODD file\n\n");
while((number=getw(f2))!=EOF)
printf("%d",number);
printf("\n\n contents of EVEN file\n\n");
while((number=getw(f3))!=EOF)
printf("%4d",number);
fclose(f2);
fclose(f3);
getch();
}
