fstream .txt and putting it into a char array to compare with another string
First of all Im new to c++, currently have a data file which is .txt,first string is the answer to the questions, example ABBCACBB, second string started with student ID space and the answer.
example of .txt
' TFFTFFTTTTFFTFTFTFTT'
'ABC54301 TFTFTFTT TFTFTFFTTFT'
'ABC54302 TTTFFFTT TFTFTFFTTFT'
I have trouble fitting them into a char and comparing.
anyone can guide me which kind of method i can use to compare them and output should be similar like this:
example of output n
' TFFTFFTTTTFFTFTFTFTT'
'ABC54301 TFTFTFTT TFTFTFFTTFT 14/20 80% A+'
'ABC54302 TTTFFFTT TFTFTFFTTFT 13/20 75% B+'
Thank you and sorry for the trouble.
btw my data.txt got about 150 entries.

Don't attempt to "fitting them into a char", usestd::stringinstead. Using that andstd::getlineit becomes very easy to read the file.

but i do need to compare them letter by letter from char[10] to char[x] to get the final result?

That's still possible.

i know how get line works, while (getline(data,output,'/n') then how do i take the 10th character to compare with the 10th character of the second line?

std::stringhas aoperator, that can be used just like for an array. So read the first line separately and save it. Then use e.g.current_line[10] == first_line[10].
