Question

I need to use gcc to build c++ files and gcc command is like "gcc -g test.cpp -lstdc++ -o out". How can i know which c++ version is used to build test.cpp?

First of all don't use gcc -lstdc++ , use g++ instead. The used C++ version can be seen in the output of g++ --version . gcc --version shows the same output
