what should i do? help please
doug4 (1538)
Did you post the correct file? Line 44 is an else statement, and there is no assert statement and no variable named stream.
theone23 (3)
yeah, so i do not know what to do. somehow know any solution? please
ljs (48)
but there is no main function so it cannot be the whole program!

ok, i just ran it... and it also tells me this debug assertion at lin 44 stuff.

You open a file at the second line of the main function... and on my system that file is obviously not there, so the f1 pointer points to zero.
then it reaches the line
while (!feof(f1))

and because f1 is zero it crashes with the debug assertation you mention. So probably that file is not there on your system, or you have se the working directory in the wrong folder.

Anyway, better to check if that file pointer f1 is zero or not before proceeding.
