Using scanf to read in certain amount of characters in C?

Question

I am having trouble accepting input from a text file. My program is supposed to read in a string specified by the user and the length of that string is determined at runtime

You can also use fread, where you can set a read limit:

char string[5]={0};
if( fread(string,(sizeof string)-1,1,stdin) )
  printf("\nfull readed: %s",string);
else
  puts("error");
