Format strings in fscanf

Question

I would like to use fscanf to read from a file that's a list of numbers (the length is arbitrary)

42
20
8
5
0

However, I am not sure how to construct a format string that reads an arbitrary number of values like this.

Answer 1

Try this

while(fscanf(fp,"%d",&number) == 1)  
{  
       printf("%d",number);  
}

fscanf returns the number of items read and returns EOF on end of file
