sscanf (line, \"Value of integer: %d\\n\", &         


        

Answer 1

The right format to read a uint64_t (typedef unsigned long long int) is, with scanf and not sscanf, "%" SCNu64 and for print is also SCNu64 Example. in your code you read for example my_integer variable, then you do scanf ("Value of integer:%" SCNu64, & my_integer); and to write the same but with printf.
