Problem $3$ Temperature

Write a C$++$ program that reads daily temperature data for a month and calculates the average temperature for each day and the overall temperature of the month. The program should read the data for the entire month from a file named temperatures.txt $($given$).$ Assume the month has $30$ days. The input file contains one line for each day, where each line has $4$ temperature readings $($in degrees Celsius$)$ for that day, separated by spaces. Adjust decimal placed as per the below sample output.
