Join Peggy Fisher for an in-depth discussion in this video Solution: Process files, part of Learning C++.
…Okay, I hope you had fun with this last challenge.…I'd like to show you one example way of solving this problem.…Let's start by taking a look at our challenge.txt file.…We wanted a file that had two columns worth of numbers.…All of my numbers are just separated by a Tab key, and I have six rows of numbers.…Let's go back over to challenge.cpp.…In the main part of the program, I need some variables to hold each of the column…numbers that I read, and also a variable to…hold the total for column one and column two.…
I only need one variable for the count, because…both columns are going to have the same number of items.…Next, I added a new error code called readError,…and I set it to the value of 20.…This will be the error that I'll throw whenever I…have a file error trying to read my input file.…I declare my input file as IF stream inputfile.…Then I have my try and catch block of code.…If the inputfile.fail, meaning that it couldn't…find the file, it's going to throw the readError.…In the catch, I check to see which error was received.…
