hi @sakshamngplsn_8a4528baa287a8ff
its a very simple ques… u just have to check if character is lowercase or uppercase…
refer my code -->

#include <iostream>
#include <string>
using namespace std;
int main() {
    char ch;
    cin>>ch;
    if(ch>='a' and ch<='z'){
        cout<<"lowercase";
    }
    else if(ch>='A' and ch<='Z'){
        cout<<"UPPERCASE";
    }
    else{
        cout<<"Invalid";
    }
}
