Can somebody help me to check which part of my code is wrong????

#include <stdio.h>
int main(void)
{
	long int num1, num2;
	while (scanf("%ld %ld", &num1, &num2) == 2 && num1 > 0 && num1 <= num2 && num2 <= 1000000000 && num2 - num1 <= 100000)
		for (long int i = num1; i <= num2; i++)
		{
		if (i == 1)
			continue;
		for (long int n = 2; n <= i; n++)
		{
			if (n == i)
			{
				printf("%ld\n", i);
				continue;
			}
			if (i%n == 0)
			{
				break;
			}
		}
		}
    return 0;
}

You're not dealing with the first number in the input.

The input begins with the number t of test cases in a single line (t<=10).

You're not dealing with the first number in the input.

The input begins with the number t of test cases in a single line (t<=10).

so I need to write a test condition for first input in single line or it can be compound with the while statement that I have written?

It's not your responsibility to verify the input constraints. You can assume they are accurate.

My point was that you're not even reading it in.
