Write a program sum of the two numbers in hexadecimal. that reads in two hexadecimal numbers from a file, hex.ext, and prints out the From Wikipedia: "In mathematics and computer science, hexadec hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0-9 to represent val and A, B, C, D,E, F (or alternatively a-f) ues zero to nine, to represent values ten to fifteen AF3 is equal, in decimal, to THE SUM OF: For example, the hexadecimal number 2 (2x 16') + (10 x 162) + (15 x 16') + (3x ie) og 10,995." For example, if the file contains: 45AF 12B3 ...and then your program will output (if you output the result in decimal): sten (Haxt) The decimal sum of 45AF and 12B3 is 22626. (To check your results, you can go to a hexadecimal calculator on the Web. For example, http://www.csgnetwork.com/hexaddsubcalc.html) To solve this problem: Read the hexadecimal numbers as character arrays Convert the charac character array as a parameter, and returns an integer) Add the numbers to get a decimal sum EXTRA CREDIT: convert the sum to hexadecimal (by calling a function that fills a) b) ter arrays to numbers (by calling a function that takes the c) d) a character array) PART II Assume that your file has an unknown number of hexadecimals. Modify/ Enhance/Change the program so that it prints the sum of all the numbers in the file
