In this line of code, what does 144 refer to? newFlavors. read(144)
the number of lines in the file called newFlavors

the number of characters to be allocated for readable memory in the file called newFlavors

the number of times that the file called newFlavors should be read

the number of characters from the file called newFlavors that should be read

If you have fixed length lines/records in the file then get the size of the file and divide by the size of the record to get the number of lines/records. Remember to add the \n to the size of the record.

If you don't, then you need to scan the file and keep reading each character, counting the \n, until you reach end of file. The count will be the number of lines. This is a simple while loop.

Every time you open a file for reading the file pointer should be reset to the start of the file.

The correct answer would be a.
