calculate the sum of all the even numbers between the range the user inputs

***************** Calculate the sum of all the even
numbers between the range the user inputs *************

This is what I have so far... but something is wrong and I can't figure it out... I keep getting 0 (zero) when I run the program. Please Help!



#include<stdio.h>

int main()
{

int display, min, max;
int sum=0;
int counter1, counter2;

printf("Enter minimum value: ");
scanf("%d", &min);

printf("Enter maximum value: ");
scanf("%d", &max);

counter1=min%2;
counter2=min+1;

if (counter1>0)
{
for (display=counter2; display<=max; display=display+2)
sum=sum+display;
}

if (counter1=0)
{
for (display=min; display<=max; display=display+2)
sum=sum+display;
}

printf("%d", sum);


}

Try using the code below:

#include<stdio.h>

int main()
{

	int display = 0, min, max;
	int sum=0;
	int counter1, counter2;

	printf("Enter minimum value: ");
	scanf("%d", &min);

	printf("Enter maximum value: ");
	scanf("%d", &max);

	if(min%2==0)
	{
		min = min;
	}
	else
	{
		min = min+1;
	}

	if (min>0 && max>1)
	{
		for (display=min; display<=max; display=display+2)
		{
                        sum = sum+display;
			
		}
	}
	else
	{
		printf("Either counter1 is negative or counter2 is negative");
	}
printf("%d", sum);
return 0;
}
