I was making a program takes maximum number (n) from keyboard and finds the divisors and sum of this divisors for each integer from 1 to n,when i didn't use the sum part of my code it prints perfectly, but when i try to print with sum it gives wrong numbers:

it works perfectly :

<pre>int main()
{
	
	int x,n,sum,c;
	printf("Enter a maximum number :");
	scanf("%d",&n);
	

	for(c=1;c<=n;c++)
	{
	
		for (x = 1; x <= c; x++)
		{
			if(c%x == 0)
			{		
			printf("%d ",x);
			
		
			}

		}
		printf("\n");
	}

}

What I have tried:

when i try this to add sum part it gives wrong numbers:

int main()
{
	
	int x,n,sum,c;
	printf("Enter a maximum number n :");
	scanf("%d",&n);
	

	for(c=1;c<=n;c++)
	{
	
		for (x = 1; x <= c; x++)
		{
			if(c%x == 0)
			{		
			printf("%d ",x);
			sum=0;
			sum=sum+x;
			printf("%d",sum);
			
		
			}

		}
		printf("\n");
	}
