when I do
FILE *f = fopen(...);
double k = 10;
fprintf(file, "k\x00%f", k);
only the string "k" will be written to the file (And this is the problem, since
I want the strings "k" and "10.0" to be separated by the symbol with the code
0).
If I do
fprintf(file, "k\0x20%f", k);
then the correct string "k 10.0" will be written to the file.
