Question

I’m trying to read a text file built with the following format in every line:

char*,char*,int

i.e.:

aaaaa,dfdsd,23

bbbasdaa,ddd,100

i want to use fscanf to read a line from file, and automatically parse the line into the varilables string1,string2,intA

What’s the correct way of doing it ?
Thanks

Assuming you have:

char string1[20];
char string1[20];
int intA;

you could do:

fscanf(file, "%19[^,],%19[^,],%d\n", string1, string2, &intA);

%[^,] reads a string of non-comma characters and stops at the first comma. 19 is the maximum number of characters to read (assuming a buffer size of 20) so that you don’t have buffer overflows.
