Question

C++

Write a program which accepts a character from the user. If the character is between 0 and 9, it will output that it's a digit. If the character is lowercase it will output that its a lowercase character. If it's an uppercase character it will output that it's uppercase. For all other cases it will output that it's neither a digit nor a letter. As an example of the output:

   Enter a digit or a letter: A
   You entered an uppercase character.

#include<iostream>
using namespace std;

int main() { 
   char ch;
   cout<<"Enter a digit or a letter: ";
   cin>>ch;
   
   if(ch >='0' && ch <='9'){
      cout<<"You entered a digit"<<endl;
   }
   else if(ch >='A' && ch <='Z'){
      cout<<"You entered an uppercase character."<<endl;
   }
   else if(ch >='a' && ch <='z'){
      cout<<"You entered an lowercase character."<<endl;
   }
   else{
      cout<<"You entered neither a digit nor a letter."<<endl;
   }
   return 0;
}
