Simple example of retrieving the total number of elements.

#define FCF_TEST_IMPLEMENTATION #include <fcfTest/test.hpp> #include <iostream> FCF_TEST_DEFINE("HistogramDemo", "Counter", "GetCounter") { fcf::NTest::HistogramBasic<int> hist; hist.append(1); hist.append(2, 10); hist.append(3, 5); size_t total = hist.counter(); fcf::NTest::log() << "Total items: " << total << std::endl; FCF_TEST(total == 16); } int main(int a_argc, char* a_argv[]) { bool error = false; fcf::NTest::cmdRun(a_argc, a_argv, fcf::NTest::CRM_RUN, &error); return error ? 1 : 0; }

Output:
