Yes. Each element must be transformed into either a string or
a character, then appended to the string (you didn't specify
the type of the array).

If the array is an array of characters, you could always complare [sic]
each element of the array with an element of the string:
string hello_string("hello");
const char * hello_c_string = "hello";
[1] if (array[0] == hello_string[0])
...
if (array[0] == hello_c_string[0])
...

You can only compare an element of an array to a string if the
each element of the array is a string:
string many_strings[400];
string hello_string("hello");
if (many_strings[0] == hello_string)
....
If you want to compare arrays of characters to C-Style strings
{which are arrays of characters with a NUL ('\0') character
at the end} there are many functions to help you:
strcmp() -- both parameters must be C-style strings.
strncmp() -- useful for arrays of characters or C-Style strings.
std::string::c_str() -- Useful for converting an std::string
into a C-style string.
By far, the easiest method for handling text is to use the
std::string class. This class overloads the equality operator
(==) (as well as other operators) for comparing strings:
string hello_string("Guten Tag");
string world_string("Welt");
if (hello_string == world_string)
