array

[CASHOUT]

Okay new submission for my last question. I was a little mixed up before. Honestly I kinda still am.

If the user puts in a 6. I need the array to display the even number from 0 - 6.

Right now what it does is it displays the first six even numbers.
Okay as I'm writing this I'm starting to see where my problem might be..

void sumIntegers ()
{
int arr[50];
int i = 0;
int num = 0;
int sum = 0;

	
		printf("\nI want to sum up even integers <= 50.\n\n");
	

	do
	{
		printf("\nPlease enter a positive integer:\n\n\t\t\t");
			scanf(" %d", &num);
			
	
			if(num < 0)
				printf("\n*** Negative numbers are invalid! ***\n\n\n");

	
			
	for (i = 1; i < num; i++)
	{
		arr[i] = 2 * i;
	}
	
	
	for (i = 1; i < num; i += 1)
	{
		printf("%d\n", arr[i]);
	}


	for(i = 1; i < num; i++)
	{
		if (arr[i] % 2 == 0)
		sum += arr[i];
	}
	}
	while(num <= 0);

	printf("\n\nThe sum of the even numbers from 0 to %d = %d\n\n\n", num, sum);

	return;
}

Time for some codelab. I'll come back to this
