Number converter

Menu Convert between integer, binary, octal and hexadecimal

This program should accept numeric values in hexadecimal, decimal, octal and binary formats as:

Hex 0x0 to 0xFFFFFFFF Dec 0 to 4294967295 Oct o0 to o37777777777 Bin b0 to b11111111111111111111111111111111

After a value is input the code in main will interpret the data types above an process the conversion to an unsigned int. The unsigned int will be used to convert the input to strings containing hexadecimal, octal and binary strings.

Part 1: Converting data types (50 points) In this project, you will write code to convert strings containing hexadecimal. Decimal, octal and binary strings to an unsigned integer. Some of the code is completed for you. Open the Convert source code file and look at the completed code and comments. The description and comments in each function should help you complete this project. To convert from hex string to unsigned int, accumulate the position-wise values of each character in the string. Remember that you can perform math operations on char data because they are numbers and have specific positions in the ASCII table. This method is like the one shown in lecture. Convert OxFFFF to a unsigned char, considering that F 15 and each hex char a multiple of 16: 15 *115 1615 25615* 4096 65,535 This process is similar with decimal, octal and binary. To from an unsigned int 16,535 convert to hex: 1. 2. 3. 4. 65,535 / 16 = 4095 and 65,535 % 16-15 4,095 / 16 = 255 and 4095 % 16-15 255 / 16 = 15 and 255 % 16 15 15/16=0and 15 % 16 = 15 Collect remainders for the hex values in reverse of these steps. 15 15 15 15 -> 0xFFFF This is a similar process for base-10, base-8 and base-2 conversions.
