RE: Suppose there is a txt file with following format:...

Since the number of subject for a perticular student is unknown and A is a valid grade, If a + symbol is replaced by a A then it would be impossible to find out without any other correct source of the same student's grades that the "A" there is occuring by mistake.
Hence it is impossible to write the programm. |
