    Hm... something like isupper, or islower? Or perhaps toupper and tolower.

    Quzah.
    Hope is the first step on the road to disappointment.

    I think what you are looking for.. are the tolower() and toupper() functions.. located in the <cctype> library


    Code:
    #include<iostream>
    #include<cctype>
    using namespace std;
    
    int main()
    {
    
         char choice;
    
         cout << "Enter menu choice: ";
    
         cin >> choice;
    
              switch(toupper(choice))   //turns all user entries to upper case
              {
    
                        case 'A':  function_call();
                        break;
    
                        case 'E':  cout << "Bye";
                        exit(0);
             }
    
    return 0;
    }
