Help with data type
Hello all,
I am supposed to multiply 10 float values. (like 0.002, 0.004, 0.006, etc...)
Which data type will best suit the product of these float values?
I used 'long double' but I am still getting 0 as the product.
(I have initialised the product as 1. So, no problem with that.)
Can someone suggest a suitable data type which can handle longer decimal places. Also pls mention the representation to be used ie.%f... -
thankyou
i will try it out

Running programs in a batch
hello all,
i have around 200 .csv files.
i have written a code which opens one file, sorts the data in the file and gives the required output.
i have to do this for all the 200 files.
should i change the file name in the fopen statement everytime and run the program 200 times?
or is it possible to analyse all the files at a time (in a batch)
any help will be highly appreciated

data from a csv file
hello all,
i've to write a C code to read data from an excel sheet (in CSV format) into a 2 dimensional array.
the csv file has 100 columns and 5000 rows.
but i am supposed to read in only 19 of these 100 columns.
the 19 columns which i require are D, E, P, W, BC, BD, BO, CU, CV, etc.
so you can see that the required columns do not occur together in the original excel file.
can someone help me out?
