Thread: problem with login thingy....

whenever i log in as admin... then logout...
it automatically logs in as student and shows the student menu....
i can figure out why... here's my main code... if you want to see the rest of the code, ill post but i think its only in my main.... any suggestions?

Code:

int main(void)
{
	STUDENT array[20];
	char username[50];
	char password[50];
	char option;
	int slot;
	int i;

	for(i = 0; i < 20; i++)
	{
		array[i].stud_num = 0;
	}

	clrscr();

	while(strcmp(username,"quit") != 0 || strcmp(password,"quit") != 0)
	{

	login(username, password);

	for(slot = 0; slot < 20; slot++)
	{
		if(atoi(username) == array[slot].stud_num && atoi(password) == array[slot].stud_num)
			break;
	}

	if(strcmp(username, "ADMIN") == 0 && strcmp(password, "admin") == 0)
	{
		option = '0';

		while(option != 'x')
		{
			option = admin();

			switch(option)
			{
