call a void function that will be passed the 2 arrays

[sr2cute702]

Hello,

Could you provide the code to perform the following task below.


declare 2 arrays that can each store a maximum of 20 double type values


interactively prompt the user for the name of an input file and read the file name

read the content of the file
o first value in the file will be an integer, n, that is greater than 0 and less than or equal
to 20
o n indicates how many values are to be stored in one of the arrays
o read the n values and store them into one of the arrays


double the value of each of the elements in the input array that have even
subscripts (0,2,4,...) and store them in the corresponding locations of the
second array
§ determine the cube root of each of the values in the input array that have odd
subscripts (1,3,5,...) and store those values in the corresponding locations of
the second array
§ print (to the screen) the content of both arrays (in 2 right justified columns
with headings)
§ return to main
• call a value-returning function to sum all the values in the input array and then call the
function again to sum the first int(n/2) values in the second array
o the function should be designed to receive 2 parameters, an array of doubles and an
integer, size
o the function will add the first size values in the array and return the result
• print the sum of all the values in the input array with a label
• print the sum of the first int(n/2) values in the second array with a label





sample of the type of data it might read.

11


0.0    13.0  27.0  -27.0  -9.0  5.0 11.0  1.0 21.0   -1.0  16.0

Expected output to look like.

Input Array   2nd Array
0.00000       0.00000
13.00000      2.35133
27..00000     54.00000
-27.00000     -3.00000
-9.00000      -18.00000
5.00000       1.70000
11.00000      22.00000
1.00000       1.00000
21.00000     42.00000
-1.00000     -1.00000
16.00000     32.00000
Sum of all Values in array 1: 57.00000
Sum of first 5 values in array 2: 35.35133

No, we are not going to "provide the code to perform the following task below." We are not learning this, you are. If you are stuck somewhere that's fine but ask about a specific problem and show where in your code you're stuck. Go as far as you can on your own. We are here to help not do your homework.

Any good reference material that could guide me on completing my program?

[joe864864]

Google, StackOverflow, right here. Chances are someone has had your same question so google it and see what comes up, but you have to have a specific problem. If your having trouble with a specific part of your code ask about it here. If you're having trouble with the bigger picture or how to tackle it you can ask here but sometimes its best to take a step back and break the problem down into the smaller parts. Each one of those bullets is all separate smaller problem to solve so pick one. For example, starting at the top you need to get the name of the input file, then read in the data, separate it and store it in an array. So create a fresh project and try to solve just that problem.

Other suggestions: Drawing/writing it out on paper can sometimes help. Also, taking a step back, standing up and walking a bit can help. If all else fails to help, sleeping on a problem is surprisingly effective.
