You Will Write A Program That Acts Like A Simple Calculator For Binary

You will write a program that acts like a simple calculator for binary numbers. You should read in a string of input that has the format: number operator number. Each of the numbers should be presented in two's complement 8-bit form. So an input string might look like + . You can assume that the user will enter the data in the proper format.

You do not need to do error checking of the format. You should divide up the input string into its three parts. You should then determine which operator is being used. The valid operators are +, -, *, and /. Based on the operator you should perform the corresponding mathematical operation on the two numbers after you convert each string of 1's and 0's into its proper corresponding decimal value.

Based on the resulting value you can either display an error message about overflow occurring if the result is too big, or you can you can echo the desired calculation along with the answer you computed after converting it back into two's complement form. You should also print an error message if the calculation is supposed to divide by zero. Lastly, you should place this task inside a query loop that asks the user whether or not to continue performing calculations. Make sure that you properly comment your program. Submit the source file along with sample output of your program demonstrating each of the calculation types here on Blackboard.

In this paper, I will develop a simple binary calculator program that operates on 8-bit two's complement binary numbers. The program will accept user input consisting of a binary number, an operator (+, -, *, /), and another binary number. It will convert these binary strings into decimal equivalents, perform the specified arithmetic operation, handle potential overflow and division-by-zero errors, then output the result in binary form. The process will be encapsulated within a loop that allows users to perform multiple calculations until they choose to exit.

The first step involves parsing the user input. Since the input format is controlled to be correct, the program will split the input string into three parts: the first binary number, the operator, and the second binary number. For example, an input might be "+ 01111111 00000010" which represents adding 127 and 2 in binary.

The conversion from binary to decimal must correctly interpret two's complement representation. In 8-bit two's complement, the most significant bit indicates the sign of the number: '0' for non-negative and '1' for negative numbers. For positive numbers, conversion is straightforward by interpreting the bits as an unsigned integer. For negative numbers, the program will convert the binary string to its decimal equivalent by first computing the unsigned value and then subtracting 256 to obtain the correct negative decimal.

Once the operands are converted to decimal, the calculator performs the operation according to the operator provided. For addition, subtraction, multiplication, and division, the program must handle overflow situations, which occur if the result exceeds the range of an 8-bit signed integer (-128 to 127). This involves checking whether the result exceeds this range before converting it back to binary. If overflow occurs, an error message is displayed.

For division, the program must also handle division by zero gracefully by displaying an appropriate error message. When division is performed, the division result should be truncated toward zero to stay consistent with integer division semantics.

After computation, the program converts the decimal result back into an 8-bit two's complement binary string. This involves checking if the number is negative—if so, adding 256 to the value and then converting to binary to get the correct two's complement form. The output displays the original calculation in both binary forms, the operator, and the result in binary, unless an error (overflow or division by zero) occurs.

The entire process is embedded within a loop that repeatedly prompts the user for new calculations. After each operation, the program asks if the user wants to perform another calculation, allowing for multiple computations in one session.
