You need to #include <cstdlib>
Source: http://en.cppreference.com/w/cpp/utility/program/system
Also, try to avoid system
, it’s dangerous. To pause the program when it’s finished, put a breakpoint on the }
at the end of main. There isn’t a standard way to clear the screen unfortunately.
For future reference, the red squiggles are intellisense errors, which are shown by a different front-end than the one that actually compiles the code, so the red squiggles are sometimes wrong, especially with complex templates. In most cases, including this one, it’s correct though.
