Output should be as show below:
and files are attached.
1. Here is example output for input file electricity.txt:
number of integers in file "electricity.txt" = 4
index = 0, element = 1877
index = 1, element = 1923
index = 2, element = 1879
index = 3, element = 2000
2. Here is example output for input file groceries.csv:
number of integers in file "groceries.csv" = 6
index = 0, element = 3
index = 1, element = 12
index = 2, element = 1
index = 3, element = 1
index = 4, element = 5
index = 5, element = 1
3. Here is example output for input file 1000.txt:
number of integers in file "1000.txt" = 1001
index = 0, element = 1000
index = 1, element = 2
index = 2, element = 3
index = 3, element = 5
index = 4, element = 7
index = 5, element = 11
index = 6, element = 13
index = 7, element = 17
index = 8, element = 19
index = 9, element = 23
index = 10, element = 29.....
............................................
.....index = 995, element = 7877
index = 996, element = 7879
index = 997, element = 7883
index = 998, element = 7901
index = 999, element = 7907
index = 1000, element = 7919
I am having trouble reading the integers an putting them into an array...below is the code I have so far.
