+/*
+Write a function, reverseDigit, that takes an integer as a parameter and returns the number with its digits reversed. For example, the value of reverseDigit(12345) is 54321; the value of reverseDigit(5600) is 65; the value of reverseDigit(7008) is 8007; and the value of reverseDigit(-532) is -235.
+
+You may name the program as you please, for example, "DigitReverser.cpp"
+
+Please make sure the program compiles and runs as it should!
