I want to use unordered map in c++14/c++ but I am unable to do it in code::blocks, it shows an error saying “”
#error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
try compiling using “g++ -std=c++11 FILENAME” or by using “g++ -std=gnu++11 FILENAME”
Thanks @yoda_101 it really worked. Welcome to codechef community.
