did you check what is the meaning of fread return value?

[severe root]

man7

fread(3)

fread, fwrite - binary stream input/output

Synopsis

#include <stdio.h>

size_t fread(void *restrict ptr, size_t size, size_t nmemb,
             FILE *restrict stream);
size_t fwrite(const void *restrict ptr, size_t size, size_t nmemb,
             FILE *restrict stream);

what do you mean as in the fact it returns 0 if it cannot read into the file?

[waxen yacht]

it also returns 0 at the end of file

so you need to check what actually happened

fread() does not distinguish between end-of-file and error, and
callers must use feof(3) and ferror(3) to determine which
occurred.

[hot kindle]

asin whether it just reached the end of the file or if there was an error?

ah okay

sorry i am a beginner at all this im a bit confused how would i check for this?

[waxen yacht]

those are just another functions to call

[severe root]

man7

feof(3p)

feof — test end-of-file indicator on a stream

Synopsis

#include <stdio.h>

int feof(FILE *stream);

man7

ferror(3)

clearerr, feof, ferror - check and reset stream status

Synopsis

#include <stdio.h>

void clearerr(FILE *stream);
int feof(FILE *stream);
int ferror(FILE *stream);

"error in code using fstream" is pretty misleading as you don't even use std::fstream xD
