C Program Prime Numbers between 2 given numbers

 C Program Prime Numbers between 2 given numbers

#include<stdio.h>

main()

{

  int num1,num2,i,count=0,j;

  printf("Enter a number 1\n");

  scanf("%d",&num1);

  printf("Enter a number 2\n");

  scanf("%d",&num2);

  printf("The Prime numbers between %d and %d are\n",num1,num2);

  for(i=num1;i<=num2;i++)

  {

    count=0;

    for(j=1;j<=i;j++)

    {

      if(i%j==0)

      {

        count++;

      }

    }

    if(count==2)

    {

      printf("%d\n",i);

    }

  }

}

Output:-

Enter a number 1

2000

Enter a number 2

2100

The Prime numbers between 2000 and 2100 are
