reading files

Hi!i need your help..

i will read one of the lines of a file like

name surname age sex local .....(some more can be added)

and pass this words to a structure as arguments of it like students.name, students.surname...

but number of words can be change that means some more can be added or vice versa..

how can i pass them dynamically to a "students" structure?

Hi btocakci,

You don't really pass them to a structure. Instead, you set the values in the structure and then pass the structure to other functions.

First, define your structure:

typedef struct
{
char Name[20];
char Surname[20];
int Age;
char Sex;
/* Add more as you need them */
} MyStruct_t;

Then after reading the line, break it into pieces with sscanf(), strtok(), or your own method. Then simply copy the pieces into the structure.

Good Luck!
Kent

but i dont know how many arguments will the structure have..That is depend on the file..Let me say if the file says me to include a "school" argument (that means file can be edited) i must be able to use this "school" as a argument of my structure..
