[ad_1] I think your problem is probably partly in the get_next_position_to function, where you increment the position of the body part passed into the function. I think this should probably only add. The ‘RIGHT’ case also modifies both X and Y. position_t get_position_next_to(body_part_t *part) { position_t pos; switch(part->dir) { case UP: initialize_position(&pos, part->pos.x, part->pos.y + … Read more

[ad_1] Consider adding a counter, bump it up on every line, and print the counter with every line. Also note fixes to set log_file, update to read command. log_file=”/home/user/log.txt” line_no=0 while read -r line do line_no=$((line_no+1)) printf “%d. %s\n” $line_no “$line” done < “$log_file” One alternative to consider is to call the nl utility, which … Read more

Not likely: distributions usually don’t ever update the major/minor version of glibc from the one they originally shipped with, because the likelihood of breaking applications is too great. You may have to build glibc-2.15, or better current glibc-2.24 from source and install it into non-default location. See … Read more
[ad_1] The Unix API is C (as is the Windows API); any calls into Unix will look like C. That doesn’t stop you from using C++, however: if the function requires a char const*, for example, you can call std::string::c_str() on an std::string. Whether you want the Unix function (e.g read()) or the C++ (>> … Read more
