How to fix gcc -Wall "embedded '\0' in format" warning
c++, g++, gcc, warnings
Solution
The warning is there for a good reason: `snprintf` is going to think the `\0` marks the end of the string. If you actually need a null to be printed, you can't embed it directly into the string; C strings cannot contain null characters for this very reason. This is the most obvious workaround:
snprintf(filePath,filePathSize,"%s%s%c",path.c_str(),s.c_str(),'\0');
Problem
This may not be very crucial, however I am trying to fix all the warnings g++ is complaining about. In the code below, I am getting "embedded '\0' in format" warning for the snprintf() line. How can I fix this? ``` int filePathSize = path.size() + s.size() + 1; char filePath[filePathSize]; snprintf(filePath,filePathSize,"%s%s\0",path.c_str(),s.c_str()); ``` Thanks in advance...
