need some tips to finish :)

Write your question here.
Hi, im just new here :) i think im finish with my project but somethings wrong
with the computation part,at first it computes the 1st set of number row but after that it just copies the number i dont know why it does not subtract anymore :)) i just need some tips to why its not working ty :)
here is my code

edit: now i know the problem clearer, i want to ask for some hints on what will i use to store the value of the subtracted results :)

#include <iostream>
#include <stdlib.h>

using namespace std;

int input[10];
int dif[10];

int dami;
int space;

int i;
int j;

int main()
{
	cout << "How many numbers you will enter, maximum of 10:\n";
	cin >> dami;
	if (dami > 10)
	{
		cout << "Number exceeds limit try again\n";
		system("pause");
		system("CLS");
		main();
	}
	else
	{
		cout << "Enter " << dami << " numbers not greater than 100000 and not lower than 0:\n";
		for (i = 0; i <dami; i++)
		{
			cin >> input[i];

			if (input[i] > 100000)
			{
				cout << "\nInput is too large";
				system("pause");
				system("CLS");
				main();
			}
		}

		cout << "\n";
		for (int z = 0; z < dami; z++)
		{
			cout << input[z] << "  ";	
		}
		/*for (space = 0; space < dami - i; ++space)
		{

			cout << "";
		}*/
		cout << "\n";
		for (i = 0; i < dami; i++)
		{
			
			for (j = i; j < dami - 1; j++)
			{
				dif[j] = input[j + 1] - input[j];
				cout << "  " << dif[j];	
			}
			cout << "\n";		
		}
	}
	cout << "\n";
	system("pause");
}

Do not call main(). You could use loops instead.

uhm i dont have problem with the main part :)

here is the problem for example i input 1 5 11 26 its output shows

1 5 11 26
 4  6  15
   6  15
    15

it should be

1 5 11 26
  4  6  15
    2  9
      7

some hints would be a big help :)

That is due to lines 58-59. You calculate differences from the original input every time.

You could, for example, replace the input with differences. That way each iteration would start with new input.

Regardless of whether you have a problem with it or not, it is not standard C++ therefore - don't do it. Use a loop instead.

The standard says in §3.6.1.3:

The function main shall not be used within a program.

I see, thank you for your replies :)
