C++: Reading a CSV File

[apextwin]

Does anyone have a simple code for this ? C++ is way out of my league as i hvnt touched this language in over 4 years or more ..
Any help will be highly appreciated ..

1. The hint is in the file extension.
2. Loop through the file.
3. Stop at commas and process.

I knw the method but its just the fact that i would have to learn the VC++ all over again .. Being lazy dsnt help also .. So if someone has it then no it would make my life a lot easier

u can use strtok() function to get tokens separated by commas.

^ Yeah i was reading that .. could u perhaps explain wat does it excatly mean ? ..
Also could u guys tell me which VC++ project type should i select for this .. I dont want any output so Win32 is out ..

no idea about VC++. About strtok(), check out some examples from the internet. Here's a brief info:

suppose you have a file which has the following contents:

a,b,c,d,e

now, you want to read individual tokens separated by comma. Tokens are simply values that are separated by commas, for e.g. a b c etc...

now, you can use strtok to get the tokens as follows:

First read the file and get the current line (maybe using fgets) into array line
char *token;
token = strtok (line, ",");
while (token != NULL) {
token = strtok (NULL, ",");
}

So, to get the tokens you have to call strtok 2 times. Once with the array argument containing the contents to be parsed and then again with NULL argument. The 2nd argument is the token separator (comma in ur case).

I hope this helps...

Thanks monty .. I had some trouble implementing Strok with all these complier options in VC++ .. It worked but now i am using a string split function in VC++ ..
Maybe we should have a code library in Erodov for such commonly used functions

^^In VC++, File->New->Project->Win32->"Win32 Console Application" for all the console/dos applications.
