Given three int variables that have been declared and given values, areacode, exchange, and lastfour, write a string expression whose value is the string equivalent of each these variables joined by a single hyphen so if areacode, exchange, and lastfour, had the values 800, 555, and 1212, the expression's value would be "800-555-1212". alternatively, if areacode, exchange, and lastfour, had the values 212, 867 and 5309 the expression's value would be "212-867-5309".
