+Decimal (Base 10) is the standard counting numbers system. 
+Hexadecimal (Base 16) is used for various purposes such as 
+ -  assembly programming languages and in machine code. 
+ -  It is often used to refer to memory addresses. 
+ -  It can be used during the debugging stage of writing a computer program and to represent numbers stored in a CPU's registers or in main memory.
+
+DecToHex lets the user enter any integer and displays its hexadeicmal (base 16) conversions. 
+Its main purpose is to allow users to understand the mathmathics behind decimal to hexadecimal conversions.
+
+
+
+This challenge requires that the developer implementing it follow these
+constraints:
+
+-   Since, the main purpose of the program is to allow users to understand the math behind decimal to hex conversions, the 'hex' function may not be used
+
+
+
