to read a file in C and use the data

[nalinibh]

Hello everybody

I am quite new to C.I want to read a file and store the data in an array.And i also want to calculate the data_length of the file.

Please can anyone help

i have tried somethg like calculating number of char in the file but that doesnt give me the data_length of the file.

FILE *fp;
int noc=0;
char test[80];

char ch;
fp = fopen("/TC/MODPROJ/PR1.TXT","r");

while (1)
{
ch=fgetc(fp);

if (EOF==ch)
break;


noc++;


Can anyone please help me

thanks in advance

A quick and easy way is to read your file *twice*; the first time you read all your
data but don't store anything but when you've read everything you know how
many data items are in that file. Close the file, open it again and read everything
again, but now you have allocated an array of exactly the size you need so
you can store all your data.

kind regards,

You can also fseek() from 0 (the start of the file) to SEEK_END.

Then do a tell().

The tell returns the number of bytes from the beginning of your file.
