Write a C program that reads a csv file and find the monthly weather statistics.

Requirements: $-$ The weather file is in comma$-$delimited csv format, and the first line is the header

line. $-$ The weather file contains three columns: month, day and temperature. $-$ You find the average for each month. $-$ Your program should check if the month is from $1$ to $12$ and the day is from $1$ to

$31.-$ If there are multiple rows for a specific month and a day, only use the first row for

calculations.

o Hint: you can maintain a $2$D array $($month x day$)$ to keep track of which days

have already been used for calculations. $-$ The average temperature is calculated by $($total temperature$)/($number of days

calculated$).$

o For example, if there are $10$ days for January, the temperatures will be

summed and then divided by $10$ to find the average temperature. $-$ The statistics should be written in the output file named: $($csv filename$).$txt$,$

without the parenthesis.

o For example, if the csv filename is $$weather$.$csv$,$ the result will be recorded in

$$weather$.$csv$.$txt$.-$ You can print out the content of the output file using the $$cat$$ command. The

below is the usage of the command.

o cat $-$ Follow the example interaction for the output format.

Example Interaction $($all interactions are command$-$line interactions$)$:
