Great video, exactly what I needed plus some!

Dude, you're telling me that getline function takes an extra (until)argument😂? I did my University project few days ago. I sorted every line using different characters for diff info and fetched everything separately. I'm feeling like an idiot right now🤓.

how i do it for multiple csv files like 10-20 ? and like put it in one place all ?

S-O man, u'r a monster

How can I ignore the first line of the file? Say, in a csv file, the first line is usually the titles (Name, Age, Birthday) and wanted to skip it and have it read to the 2nd line, that contains the values?

@BeginningProgrammer

2 жыл бұрын

read the line but don't store it in memory. Just do a getline before the loop begins

@Code Morsels thank you. Is there a way to put the getline inside the while in another loop? Because my file is a csv that has date in a string, and a bunch of float in another columns. I have a stock data: date (string), (then all floats) open, high, low, adjust close, volume, percent change. Wondering if there is a shortcut instead of using atof each time

@@rhettarded Have you seen this other video kzread.info/dash/bejne/ia6Hzs1sh7rIgLA.html. It has reusable way to parsing the file and you can just reuse the same code over and over. You can extract whatever columns you want out of it. For the dates you may need to add another function called getDate. And the code is at gist.github.com/fernandozamoraj/22faf8e4b2ee45cb8e0f7dc5110319e7

How can we search a student record and bring out everything about that particular structure from the vector container?

@BeginningProgrammer

2 жыл бұрын

the most straight forward way is to simply iterate over the vector sequentially and find the item by comparing the attribute. Or you can use the vector's find_first_of www.cplusplus.com/reference/algorithm/find_first_of/. Vector's are not very good for searching. A better option may be a map, if you are mapping by the id.

How parse dcm file

So.. data files fall into three broad categories flat files, mark up files, markdown which in a way it's actually a mark up. The other category is binary format. Binary formats can be open standard like PDF. I'm not very familiar with the DCM standard and have not ever seen the inside of one. But with most complex files you normally need an API. The API can provide the data contained in the file. Or sometimes you can create your own API based on the standard. Non flat files are way more complex than flat files though and beyond the scope of this tutorial.

i think C++ is not meant for this kind of job: in pure C, using strtok() or fscanf() it's more concise & cristal clear; this C++ code here is messy as hell;

Hi Marc. You may be right. However, there are times when other individuals such as students need to use C++ and strtok is not an option on the table.
