Write a C++ program called avg proc.cpp that calculates the average temperature

in your living room over a period of time based on the data from two IoT sensors.

Your program should rst request the name of a temperature text le. A text le

called temp data.txt is provided that contains a number of sensor messages sent, with

each line representing a distinct message. Each message contains a sensor name and

a temperature value which are separated by commas. The program should read the

temperature data into a suitable data structure. The temperatures for sensor 1 should

then be added to a global sum total by the parent process, while a child process should

be spawned to add the temperatures for sensor 2 to the same global sum total. After

all the temperature samples have been processed, the average temperature should be

calculated and printed by dividing the sum total by the number of samples. Assume

that the specied text le is located in the same directory as your program. The average

temperature value should be formatted to two decimal places.

IMPLEMENTATION:

1. Your program should rst request the name of a temperature text le.

2. It then reads the input le line by line and stores the temperatures in a suitable

global data structure.

3. When the reading of the input le is complete, the program creates a new child

process with the fork() function.

4. The parent process then sums up the temperature data from sensor 1 in a global

variable.

5. At the same time, the child process sums up the temperature data from sensor 2

in the same global variable.

6. When the processing of the temperature data is complete, the program calculates

and prints the average temperature by dividing the global sum variable by the

total number of samples in the input file.
