hi,
this is a code for record I/O in files:
#include <stdio.h>
main()
{
FILE *fp;
char another='Y';
struct tmp
{
char name[40];
int age;
float bs;
};
struct tmp e;

fp=fopen("emmloyee.txt","w");
if(fp==NULL)
{
puts("Cannot open file\n");
exit(0);

}
while(another=='Y')
{
printf("Enter name,age and salary of employees\n");
scanf("%s%d%f",e.name,&e.age,&e.bs);
fprintf(fp,"%s%d\f",e.name,e.age,e.bs);

printf("Another record Y/N");
fflush(stdin);
another=getche();

}
fclose(fp);
}
and this is the compilation error:
[root@localhost i-o]# gcc -o l355 l355.c
/root/tmp/ccF5ymx6.o(.text+0xcd): In function `main':
: undefined reference to `getche'
collect2: ld returned 1 exit status
this is the error anywhere the getch() or getche() are used plz tell me
how i
can solve this problem.

Wrong spell it is getchar or getc (depending on weather you want to read from stdin or a file)

Like lone_nut said, getch() and getche() aren't standard C functions.

Another thing is, fflush(stdin) has undefined results. fflush() is only guaranteed to work with output streams, not input. Here's some more information on it: http://faq.cprogramming.com/cgi-bin/...&id=1043284351

hi,
thanks for reply,i changed the getche() to getchar() ,the problem is now the program is ending with the first netry not asking for the another entry.
