Find upper lower vowels and Consonants in C++

if we put some alphabets then the program show that  capital lattes or small letters.  vowels and Consonants.

Solution :

#include <iostream>
using namespace std;
 
int main () {


    char ch;
    int isLowercaseVowel, isUppercaseVowel;

   
     cout<<"Enter any character: "<<endl;
     cin>>ch;
 
    if(ch>=65&&ch<=90)
        
   cout<<endl<<"You entered an uppercase character"<<endl;
    else
    
     if(ch>=48&&ch<=57)
     
        cout<<endl<<"You entered a digit"<<endl;
        
    else 
    
  if(ch>=97&&ch<=122)
  
        cout<<endl<<"You entered a lowercase character"<<endl;
        
    else
    
        cout<<endl<<"You entered a special character"<<endl;
        
        if( (ch>='a' && ch<='z') || (ch>='A' && ch<='Z'))
        
        cout<<"You entered an alphabet."<<ch<<endl;
        
    else
        cout<<"You entered  not an alphabet."<<ch<<endl;
        
        isLowercaseVowel = (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u');

         // evaluates to 1 (true) if c is an uppercase vowel
        isUppercaseVowel = (ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U');
        
       if (isLowercaseVowel || isUppercaseVowel)
       
        cout<<"yor given character  is a vowel."<< ch<<endl;
        
     else
        cout<<"yor given character is a consonant."<<ch<<endl;
        
    return 0;
  
}
