[C++] My code requires that I show both the outputs: Highest temperature recorde

Question

[C++]

My code requires that I show both the outputs:

Highest temperature recorded in the month of (Month goes here)

Lowest temperature recorded in the month of (Month goes here)

can anyone edit my code, and add this piece of code so that the months show as well????

Also, why can't my code read the outputfile with decimal answers???
