Answer 1

Your "fprintf(fp,"%f",*(ptr+i))" is printing unused memory. ptr 1 is set to the address of an empty heap location for a float integer. You are incrementing the unit of the memory location and printing more "0"s or unused memory. It explains why you see a bunch of 0s instead of floats. The memory calloc for ptr 1 is not stored to anything, alternately making it assigned 0 or false. If you meant to either use the value of the pointer incremented or you are creating a pointer notation of floats, make sure you are storing data.
