Thread: weird problem with gets();...

the problem is that when i only put 1 gets(); in the "Enter Student Number' portion,
it skips right away and proceeds to getting the Students name:
u can run it if ud like to see the problem....
P.S.... the for loop to fine empty slot,.... i dont know what im doing there ! xD haha sorry

Code:

void add_student(student accounts[20], FILE *file)
{
	int free;
	int i;

	for(i = 0; i < 20; i++)
	{
		if(accounts[i].stud_num == NULL)
		{
			free = i;
		}
	}

	printf("--------------------------------------------------------");
	printf("\n\nEnter student information:\n\n");

	printf("\nStudent Number [which will be the accounts username]:\n\n");
	gets(accounts[free].stud_num);  //i dont know why putting 2 gets(); here works, while only 1 doesnt...
	gets(accounts[free].stud_num);
	fprintf(file, "%s", accounts[free].stud_num);
	fputs("\n", file);

	printf("\nName:\n\n");
	gets(accounts[free].name);
	fprintf(file, "%s", accounts[free].name);
	fputs("\n", file);

	printf("\nNickname:\n\n");
	gets(accounts[free].nick);
	fprintf(file, "%s", accounts[free].nick);
	fputs("\n", file);

	printf("\nBirthdate:\n\n");
	gets(accounts[free].bday);
	fprintf(file, "%s", accounts[free].bday);
	fputs("\n", file);

	printf("\nCourse:\n\n");
	gets(accounts[free].course);
	fprintf(file, "%s", accounts[free].course);
	fputs("\n", file);

	printf("\n\nAccount creation successful.\n");
}

try using fgets instead of gets.gets might be causing buffer overrun.
