The book shows how to add and subtract binary and decimal numbers. however, other numbering systems are also very popular when dealing with computers. the octal (base 8) numbering system is one of these. the following table shows pairs of octal numbers:
a b
a. 3174 0522
b. 4165 1654
1) what is the sum of a and b if they represent unsigned 12-bit octal numbers? the result should be written in octal. show your work.

Assume that two parallel arrays have been declared and initialized: healthoption an array of type char that contains letter codes for different healthcare options and annual cost an array of type int. the i-th element of annual cost indicates the annual cost of the i-th element of healthoption. in addition, there is an char variable, best2.write the code necessary to assign to best2 the health option with the lower annual cost, considering only the first two healthcare options. thus, if the values of healthoption are 'b', 'q', 'w', 'z' and the values of annualcost are 8430, 9400, 7050, 6400 your code would assign 'b' to best2 because 8430 is less than 9400 and is associated with 'b' in the parallel array. (we ignore 'w' and 'z' because we are considering only the first two options.)
