if(ch>='A' && ch<='Z')
{
cout<<\n Capital Letter";
}
else if(ch>='a' && ch<='z')

Void main()
{
char ch;
cout<<"Enter a Character";
cin>>ch;

if(ch>=-65 && ch<=90)
{
cout<<"\n Capital Letter";
}
else if(ch>=97 && ch<=122)
{
cout<<"\n Small Letter";
}
else if(ch>=48 && ch<=57)
{
cout<<"\n Digit";

cout<<b<<c" "<<c;

}

else

{

cout<<c<<" "b;
