A. Reading Data From File Create a file named data.dat and enter the following numeric data: 10 15 11 -5 7 15 32 -13 12 11 17 9 43 18 -4 The file should contain three integers in each line, the integers separated by a space. There should be 5 lines of numbers in the file. 2 Now, write a program file called Lab9A.cpp. In this file, open the file data.dat for reading and average.dat for writing. In a loop, using three integer variables (NOT ARRAY), read the numbers to compute the average for each line. Then, write the computed average to the average.dat file. The averages must be saved in floating point format and there must be 2 numbers after the decimal point. You MAY NOT assume there are 15 numbers in the file i.e. your program should be generic.
A. Reading Data From File
Create a file named data.dat and enter the following numeric data:
10 15 11
-5 7 15
32 -13 12
11 17 9
43 18 -4
The file should contain three integers in each line, the integers separated by a space.
There should be 5 lines of numbers in the file.

Now, write a program file called Lab9A.cpp. In this file, open the file data.dat for
reading and average.dat for writing.
In a loop, using three integer variables (NOT ARRAY), read the numbers to compute
the average for each line. Then, write the computed average to the average.dat file.
The averages must be saved in floating point format and there must be 2 numbers
after the decimal point.
You MAY NOT assume there are 15 numbers in the file i.e. your program should be
generic.
