If its a c string you could just print out the first element in the array

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
cout << your_array[0]; // prints out first element of array
cout << your_array[0]; // prints out first element of array

Oh,well you could write a series of if/else if statements like

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
if(my_array[0]=='a' || 'A')
             cout << "A";
            else if(my_array[0]=='b' || 'B')
             cout << "B";
if(my_array[0]=='a' || 'A')
             cout << "A";
            else if(my_array[0]=='b' || 'B')
             cout << "B";

But that would be extremely long winded

Does this work?

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
cout<<strupr(s[0]).substring(0,1);
cout<<strupr(s[0]).substring(0,1);

cout<<strupr(s[0]);
cout<<strupr(s[0]);

This Does Not Work . Because strupr() takes a char* as an argument. So the argument should be a sting having a null character ie: '\0' at the end. But you give a character as its argument. This is the error.

To solve this problem, You can do two things.
First, You can use the function toupper()
But you will need an additional header file #include <ctype.h> or if you have a modern compiler #include <cctype>
Or else if you wish to use strupr() itself, heres a little snippet..

char temp[2];
temp[0]=s[0];
temp[1]='\0';
cout<<strupr(temp);
char temp[2];
temp[0]=s[0];
temp[1]='\0';
cout<<strupr(temp);
