In C++

Write a function ReadMisspelledWords to read in pairs of misspellings and correct spellings. It should have the following parameters in the order provided:

a string filename

a 2D array of strings misspelledWords[][2]

the number of rows in the array misspelledWord

an integer startIndex.

Your function should return the total number of word pairs in the array misspelledWords. Your function should open the file identified by filename and read lines from the file line by line. The file will have the following format:

misspelledWords.txt

chickn chicken

chicke chicken

chcken chicken

fsh fish

fishe fish

bubbls bubbles

bubles bubbles

per pear

peart pear

The file will be a tab separated values (.txt) file. You can identify tabs by the \t character. The first value on each line is a misspelled word, and the second value on each line is the correct spelling of that word. For example, on the first line chickn is followed by a \t and then the correct spelling chicken.

You should read these values into the 2D array so that the first column contains misspellings and the second column contains the correct spelling. For the file above and startIndex = 0, your array misspelledWords should look like this, and your function should return 9 (for 9 word pairs in the array):

[

["chickn", "chicken"],

["chicke", "chicken"],

["chcken", "chicken"],

["fsh", "fish"],

["fishe", "fish"],

["bubbls", "bubbles"],

["bubles", "bubbles"],

["per", "pear"],

["peart", "pear"]

]

startIndex identifies the row in the array at which you should begin to add the words in the file. If after calling the function a first time I called it again with the below file and startIndex= 9:

moreMisspelledWords.tsv

ocen ocean

ocan ocean

Then I would expect my array to look like this. Your function should return 11 for 11 word pairs in the array.

[

[chickn, chicken],

[chicke, chicken],

[chcken, chicken],

[fsh, fish],

[fishe, fish],

[bubbls, bubbles],

[bubles, bubbles],

[per, pear],

[peart, pear],

[ocen, ocean],

[ocan, ocean]

]

We will call your function multiple times with different files and the same array to make sure you append new words correctly!

Edge cases:

if the file does not exist, return -1

if the starting row of the array is greater than the total number of rows in the array, return -1
