Write a C program to take n files containing strings in ascending order (no duplicates within a file) and produce a file out. dat containing a line for each string (in ascending order). Even if a string str appears in multiple files, it should be output only once and, for each string, you should also output the number of files (k) containing the string. This should be done using code similar to: fprintf(outfp,"%s %d\n",str, k);

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
