Thread: having troubles with gets and EOF

Hi guys,
I'm going to write a program which i had to get at most 200 student informations and then sort them in some ways, getting input will continue until user enter EOF or 200 students information entered.
i wrote a struct for students contain firstName, lastName and studentCode.
firstName maximum size is 20 chars.
lastName maximum size is 50 chars.
studentCode maximum size is 7 chars.
and a flag to check if that segment of students array is active or not.
here is what i wrote:

Code:

#define TRUE 1
#define FALSE 0
#include<stdio.h>
#include<stdio.h>
struct Student
{
charfirstName[20];
charlastName[50];
charstudentCode[7];
int flag;
};
void studentInitializeser (struct Student* student);

int main(void)
{ 
struct Student students[200];
int i=0;
 for(i=0;i<200;i++)
studentInitializeser(&students[i]);
i=0;
gets(students[0].firstName);
 while(students[i].firstName!=EOF)
{
gets(students[i].lastName);
gets(students[i].studentCode);
students[i].
flag=TRUE;
i++;
gets(students[i].firstName);
}
return0;
}

void studentInitializeser(struct Student* student)
{
student->flag=FALSE;
inti=0;
for(i=0;i<20;i++)
student->firstName[i]=" ";
i=0;
for(i=0;i<50;i++)
student->lastName[i]=" ";
i=0;
for(i=0;i<7;i++)
student->studentCode[i]=-1;
}

the problem i have, is working with EOF,
i know that gets function return NULL if EOF entered, but i tried that too, its not working ^Z(i'm using Ubuntu) but program still waiting for input.
i attached a picture of running program.


thanks in advance for your helps.

Exactly, it returns NULL. What you do is comparing a static array with NULL, which can never be equal.
