C program to find size of text file

*Program to find size of text file

#include<stdio.h>
#define LINE 80

/* fp is file pointer, once we open file, it is pointer to opened file */

* argv[0] is executable program name and argv[1] is first
* argument given after executable file
*/

/* if we get NULL as return value from fopen()
* it means, program is not able to open file or
* file may not existed ? or given file path will be wrong
*/

}

* read characters from file and check size

while((ch = fgetc(fp)) != EOF){

/* we can add 1 to size every time but better to use sizeof to avoid issues */

}

* once we done with file we need to close it
