Hello,
I have a little program that needs to get data from two separate .csv files for afterwards parse them and translate info to vectors. Everything works fine when I am working with just one file (so just one ifstream), but when I try to use another ifstream to read the other file, the program crashes and a Windows error appears showing something like (sorry for the bad translation into English):
The instruction in 0x00435508 refers to memory in 0x00323430. Memory can't be "read".
Here is the part of the code concerned, may be it is not "well coded" (containing bad coding habits) because I have just learned how to use C or CPP, but it is enough if it works.
I would appreciate any help, thank you in advance.
