Question

This is for devc++

Write a program that takes input for name,
score and school year for 3 students from a
file textData1.txt.
Print the output back with average score
(rounded to 2 decimal places) along with
names, school year and score of three
students to results1.txt.
You will need 3 string variables to store
names of 3 students, 3 double variables to
store scores of 3 students, and 3 character
variables to store school year of 3 students.
You can define average as a double variable.
You need to use ignore and clear function of
iostream to make sure data is read correctly
and completely. You might need to use
cin.ignore(200,\n') to ignore 200 characters
or new line whatever comes first.
If the file testData1.txt has the data in the
picture below then your program should
generate the data shown in the picture below:
