Program using getw and putw functions in file Handling

#include< stdio.h >
main()
{
FILE *f1,*f2,*f3;
int number I;
printf(“Text inside the data file\n\n”);
f1=fopen(“DATA”,”W”);
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)/* Reading data from the file*/
{
if(number%2==0)
putw(number,f3);/*Write to even Numbers file*/
else

}
