Assumptions

1) Binary is a base two numeral system, which uses only 0's and 1's.

2) Decimal is a base ten system.

3) Hexadecimal is a base sixteen system, it is made up of sixteen characters 0-9 and A,B,C,D,E,F.

Binary to Decimal and Hexadecimal Pseudo Code

Input: UserInput is an integer

Length is an integer that counts the amount of characters in the input

N is an integer that counts the amount of characters in the input

Let Position be an integer that makes CharAt move onto the next character as it increases in value, 0 being the

first value

If UserInput is not made up of 1’s and 0’s or input has more than 8 characters Then

Output: “Please enter a correct binary number that is 8 characters or less”

Else

For (Position = 0, Position < Length, Position = Position +1)

CharAt is the value of the character in the UserInput at a current (Position)

Let N = N – 1

Let Answer = (CharAt * 2(N))

Let Sum = Sum + Answer

End For

Output: (UserInput)+ “Converted to Decimal = “ +(Sum)

End If

If UserInput is not made up of 1’s and 0’s or input has more than 8 characters Then

Output: “Please enter a correct binary number that is 8 characters or less”

Else If input is greater than 4 characters Then

Output on a new line: UserInput “ Converted to Hexadecimal = ”

Let Input2 be the last 4 characters of the UserInput

Let Input1 be the remaining first characters of the UserInput

Let Position1 be an integer that makes CharAt1 move onto the next character as it increases in value, 0

being the first value

Let Position2 be an integer that makes CharAt2 move onto the next character as it increases in value, 0

being the first value

For (Position1 = 0, Position1 < Length1, Position1 = Position1 + 1)

CharAt1 is the value of the character in the UserInput at a current (Position1)

Let N1 = N1 – 1

Let Answer1 = (CharAt1 * 2(N1)

)

Let Sum1 = Sum1 + Answer1

End For

If (Sum1 = 10)

Output on the same line as the last Output: “A”

Else If (Sum1 = 11)

Output on the same line as the last Output: “B”

Else If (Sum1 = 12)

Output on the same line as the last Output: “C”

Else If (Sum1 = 13)

Output on the same line as the last Output: “D”

Else If (Sum1 = 14)

Output on the same line as the last Output: “E”

Else If (Sum1 = 15)

Output on the same line as the last Output: “F”

Else Output on the same line as the last Output: (Sum1)

End If

For (Position2 = 0, Position2 < Length2, Position2 = Position2 + 1)

CharAt2 is the value of the character in the Input2 at a current (Position2)

Let N2 = N2 – 1

Let Answer2 = (I2 * 2(N2)

)

Let Sum2 = Sum2 + Answer2

End For

Else If (Sum2 = 15)

Output on the same line as the last Output: “F”

Else Output on the same line as the last Output: (Sum2)

End If

Else

For (Position = 0, Position < Length, Position = Position + 1)

CharAt is the value of the character in the UserInput at a current (Position)

Let N = N – 1

Let Answer = (CharAt * 2(N))
