Detecting EOF in C

Question

I am using the following C code to take input from user until EOF occurs, but problem is this code is not working, it terminates after taking first input. Can anyone tell me

Answer 1

EOF is just a macro with a value (usually -1). You have to test something against EOF, such as the result of a getchar() call.

One way to test for the end of a stream is with the feof function.

if (feof(stdin))

Note, that the 'end of stream' state will only be set after a failed read.

In your example you should probably check the return value of scanf and if this indicates that no fields were read, then check for end-of-file.
