Question

You are given a file results.txt with the results of an experiment as a set of integers. You need to separate these results into three categories: negative integers, even positive integers, and odd positive integers.

 

A sample of the file results.txt is shown below:

    52    49   -22    31   -66    41   -94   -45   -91   -81    65    39   -37    90   -94   -12   -24    53    59   -63    -2

   -11    29    42    51   -45    36    31   -68   -77     0    92   -32    17   -56    51   -49     1    40    79    92     9

   -73   -70   -49    68   -49    63   -52    86   -30   -61   -50    23    -5   -30    66    17    10    84   -43    52    51

…

Write a complete C++ program that reads the data from the file results.txt and separate it into the following files:

1.     A file negative.txt that contains the negative integers from the results.

2.     A file even.txt that contains the even positive integers from the results.

3.     A file odd.txt that contains the odd positive integers from the results.

 

Notes: The number of experiments is not greater than 1000, but the exact number is not known beforehand. Your program needs to check whether the file results.txt exists or not.

 

 

The negative.txt file might contain data similar to the following (note that the numbers are separated with a space):

-22 -66 -94 -45 -91 -81 -37 …

The even.txt file might contain data similar to the following (note that the numbers are separated with a space):

52 90 42 35 0 92 40 …

The odd.txt file might contain data similar to the following (note that the numbers are separated with a space):

49 31 41 65 39 53 59 …
