for문을 사용한 문제

int
main()
{
	int inputnum;
	int i,j;
//	int count;

	cout << "Input Number : ";
	cin >> inputnum;

	for (i = 1; i < inputnum; i++)
	{
		for (j = 1; j < (inputnum * 4) - (i + 1); j++)
			cout << " ";
		for (j = 1; j < i * 2; j++)
			cout << '*';
		cout << endl;
	}
	for ( i = 1; i <= inputnum;i++)
	{
		for (j = 1; j <= inputnum - i; j++)
			cout << " ";
		for (j = 1;j < i * 2; j++)
			cout << '*';
		for (j = 1; j <= (inputnum - i) * 2; j++)
			cout << " ";
		for (j = 1;j < (inputnum * 2) + (i - 1) * 2; j++)
			cout << '*';
		for (j = 1; j <= (inputnum - i) * 2; j++)
			cout << " ";
		for (j = 1;j < i * 2; j++)
			cout << '*';
		cout << endl;
	}
	return 0;
