	}
	void BubbleSort(contact b[])
	{
		int i, j, flag = 1;
		int temp;
		for (i = 1; i < 3 && flag; i++)
		{
			flag = 0;
			for (j = 0; j < (3 - 1); j++)
			{
				if (b[j + 1].debt > b[j].debt)
				{
					temp = b[j];
					b[j] = b[j + 1];
					b[j + 1] = temp;
					flag = 1;
				}
			}
		}
	}
You've forgotten to have a main() function, and the function void spravka(contact s[]) never finishes.

Thx, i fixed them but i have got another problem when trying to add a menu with the option to chose some of the functions.I had some errors with the void BubbleSort(contact b[]) function but i removed it for now.

		SCAN:


This makes no sense.
I think its ok now but i don't know how to go back to the function when i choose from the menu.I get this error "E016 too few arguments in function call", what argument i need to add ? Thx for the help.

		int menu = 0;

		switch (menu) {

Your functions take parameters.
void input(contact s[]) input expects an array of contact objects.

What are you providing?
case '1': { input(); } Nothing.

i don't know how to go back
