how to read a file and store it in a vector?

[trappytrap]

hey i have a data.csv file which has something like this...

Label,Count,Type,Time



the values for each count and type and time is some numbers rite and is separated by commas in the text file as seen.
wat i want to do is the like say for example......
i want to take all the values of say "type" and store it maybe in a vector so that i can use it for use. I was looking at some split function as well as struct or sumtin but i not sure how exactly to do it.Also it have more than one line in the text file so i have to store all the lines of say ''count''

can anyone help mee

I would say that you want a structure that represents the data on a single line and then a vector of those structures to store the data for the file.

To read the file you will need to look up the following functions

fopen - opens the file
fclose - closes the file

fgets - reads a line from the file
feof - tests for end of file

To split a line from the file into it's constituent parts to store in the structure you can either use pointers and do it manually or use strtok or alternitively load it into a string (C++ class) and use the functions of the class to work out where the constituent parts start and end.

hey thannks well i know how to open the file and read from the file.

example of wat the file.csv contains is this:

GA,0,2226444650,5,16/9/6,22:00:40
GA,1,76804458,5,16/9/6,22:00:44
GA,2,345317295,5,16/9/6,22:00:47


which represents
Label,Count,ID,Type,Date,Time
separated by commas

now i need to store the count in a vector(that is the 1 2 and 3) for future use that is between the 1st and 2nd comma. It must run thru each line(here we see we have 3 lines).

this is wat i really want to do.

having read the line into a variable use

char * strchr ( const char * string, int c );

to find the first comma

move the returned pointer on 1 (to skip the comma) and use either

int atoi ( const char * string );

or

long strtol ( const char * string, char** endptr, int radix );

to convert the following data to an integer

store that integer in a vector using member function vector::push_back(...)

vector<int> intvec;
int value = 5;

intvec.push_back(value);
