From: Wolfgang Bangerth Date: Tue, 8 May 2018 09:18:18 +0000 (+0800) Subject: Utilize the C++11 constructors of std::[io]stream taking a std::string. X-Git-Tag: v9.1.0-rc1~1170^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5fc1011824491a4a47cd2668fa58345878303c45;p=dealii.git Utilize the C++11 constructors of std::[io]stream taking a std::string. Previously, we had widely used the constructors that take a char* and for that needed to call the '.c_str()' function of std::string. This is now no longer necessary in C++11. --- diff --git a/examples/step-10/step-10.cc b/examples/step-10/step-10.cc index dee12d2561..935a287a30 100644 --- a/examples/step-10/step-10.cc +++ b/examples/step-10/step-10.cc @@ -140,7 +140,7 @@ namespace Step10 + "_mapping_q_" + Utilities::to_string(degree) + ".dat"; - std::ofstream gnuplot_file (filename.c_str()); + std::ofstream gnuplot_file (filename); // Then write out the triangulation to this file.
