What's wrong fellows?
#include<stdio.h>
main()
{
FILE *pt1;
char c;
printf("data input output");
pt1=fopen("data.txt","w");
while((c=getchar())=!EOF)
putc(c,pt1);
fclose(pt1);
printf("\ndata input");
pt1=fopen("data.txt","r");
while(c=getc(pt1)!=EOF)
printf("%c",c);
fclose(pt1);
}
Pay attention to precedence comparison != and assignment =.Code:while(c=getc(pt1)!=EOF)
getc/getchar() returns int.
Question 12.1
Use code tag.
What's wrong is that you didn't post the compiler error messages.
