adding columns in .csv file using C

[Ammara Sajid]

hey guys!
how do i calculate the sum of a column in .csv file format using C?
e.g my fie looks like this
1, 2, 3, 4
2, 3, 4, 5
3, 4, 5, 6

(the ',' shows new cell)

how do i calculate sum of each column (desired answer is like 6,9,15)

can i do it using fscanf()? if yes, how?

thanks!

Read each line
Convert the first value to integer.
Skip over characters until you find the ','
Convert the next value to integer.
Skip over characters until you find the ','
continue until done.

ummmmm...how? how do i use fscanf() for this? how do i modify the second argument of fscanf(f,"%d,[^,],%[^n]",&n) so that it reads every value in a row till \n in different variables?

I never suggested fscanf() . Use a command that can read an entire line.

Don't bother. Use a command that can read the file easier and process the line yourself.
