Answer:
str represents the name of the file to open
Explanation:
Required:
What does str represents in the above syntax
Before the inFS function can be used to access or read or write into a file, the file name has to be specified.
This could be done in any of the following ways:
1. inFS.open("abc.txt")
2. str = "abc.txt"; inFS.open(str);
In (1), the file name is specified directly into the function
While in (2), the filename is passed into a string variable which is then further passed to the inFS function.
In the case of this question, method 2 is used and the str represents the name of the file
