Error: non-aggregate type 'vector<int>' cannot be initialized with an initializer list

Question

I am a beginner in c++ and every time I run vector<int> nums = {2, 5, 3, 7, 1}; it gives me the Error: non-arregrate type vector cannot be initialized with initializer list.

Can you tell me why?

Thanks,

Answer 1

Use g++ -std=c++11 <filename> when compiling.

Answer 2

Using Druhv Sehgal's answer above, this worked for me on mac

If command not found: gcc++ try

clang++ -std=c++11 <filename>
