Temperature Readings File

• Read section 10.11: Reading a Structured File
• Read the Powerpoints from lecture for the temperature reading project
• Using the code given from the book and Powerpoints, define each function specified in the attached Temperatures.h in Temperatures.cpp
• Define the << output operator for Year:
  • Loop through each month, day, and hour
  • If the temperature for that hour has been read then output it
  • You will have to use multiple dot operators to access the nested vector elements
  • Set your precision to 2 and each field width to 12

ostream& operator<<(ostream& os, Year& y); 

• Define the helper function to convert an index to a printable month, to be used in your Year output operator:

string int_to_month(int i); 

• Use the attached main.cpp to do the following:

  • Read the attached input file temps.txt
  • Use your << operator to output each Year to both cout and an output file named out.txt

• temps.txt:

{year 2017 {month feb (1 1 68.3456 ) (2 3 66.6646 ) ( 1 0 67.2789)} {month dec (15 15 -9.2010 ) (15 14 -8.8405) (14 0 -2.0001)} } {year 2018 {month jan (30 7 62.1244 ) (5 23 61.4789 ) ( 7 11 68.6241)} {month mar (14 19 -4.2154 ) (19 9 -1.8567) (22 4 -6.876)} } 

• Output after reading temps.txt, going to both the console and out.txt:

 2017| February| 1| 0| 67.28| 2017| February| 1| 1| 68.35| 2017| February| 2| 3| 66.66| 2017| December| 14| 0| -2.00| 2017| December| 15| 14| -8.84| 2017| December| 15| 15| -9.20| 2018| January| 5| 23| 61.48| 2018| January| 7| 11| 68.62| 2018| January| 30| 7| 62.12| 2018| March| 14| 19| -4.22| 2018| March| 19| 9| -1.86| 2018| March| 22| 4| -6.88|
