C Program to Find Prime Numbers in a given Range

Program:

#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:
