Array of strings and doubles from a data file

billycca3 (3)
I've been trying to solve this problem for 8+ hrs so far and can't even get the code to fill the arrays in right. I have to read from a text file about rain data and then compute certain things. The order of the .txt file is the name of the city at the very top then on the next line the month, year, and actual rainfall. This repeats 240 times so I have 240 different data points. Right now it looks like this -

It currently prints out 12.51 as the city and input[0] but 12.51 is the very last value in the file and it should be printing Atlanta. Sorry, I know this is a long question but I don't know what else to do. Thanks for any and all help!

Hello billycca3,

A note for the future. You have a green check mark on your subject line which lets people know that you have found an answer to your question. This should only be used after you have found an answer.

I will have to load up your program to what it is doing.

I could use a sample of the input file, so that I am working with the same data that you are.

Hello billycca3,

I did some preliminary testing of your program an concluded that you need to rethink and rework the program, mostly the while loop and how you read the input file.

I do not know what you have learned so far, but a struct or class would be useful and an array or vector to hold the struct or class.

Defining your arrays with the size of "CAPACITY" is much more space than you will ever need.

Thanks Andy,

Sadly I can't use structs for this one and after continuously attempting to fix it, I just decided to drop it. We've got one drop grade and it looks like it's this one. Thank you anyways!

Hello billycca3,

Why give up so easy. Even using what you started with it did not take long to rearrange what you had to make it work.

If you are willing to skip what you will learn here you will be making your future much more difficult.

I normally don't but after 8 hrs of trying and still having two projects to turn in, those took priority

Hello billycca,

OK I understand. Any time you want to work on this one let me know.
