int main()
{
      char ch;
      printf(" Enter a character : ");

      if(ch>='A' && ch<='Z' || ch>='a' && ch<='z')
          printf(" %c is an alphabet",ch);
      else
          printf(" %c is not an alphabet ",ch);
    return 0;
}


/* check character is alphabet or not */
#include <iostream>
using namespace std;
int main()
{
      char ch;
      cout<<" Enter a character: ";
      cin>>ch;
      if(ch>='A' && ch<='Z' || ch>='a' && ch<='z')

      else
          cout<<ch<<" is not an alphabet";
    return 0;
}
