It is well known sololearn's C++ compiler is outdated and buggy. Despite many request in the past (by myself and others) it has not been upgraded. I would like to know what does it take for the Sololearn team to listen to our request? Working with faulty compiler is frustrating ! */ // http://www.cplusplus.com/reference/cstring/size_t/ size_t N = log(64) / log(4); std::cout << "value using size_t (template)= " << N << std::endl; size_t X = log(64); size_t Y = log(4); std::cout << "size_t log(64)=" << X << std::endl; std::cout << "size_t log(4) =" << Y << std::endl; float A = std::log(64) / std::log(4); float B = std::log(64); float C = std::log(4); std::cout << "float log(64)=" << B << std::endl; std::cout << "float log(4) =" << C << std::endl; std::cout << "value using float=" << A << std::endl; std::cout << "Value using no data type = " << std::log(64) / std::log(4) << std::endl; std::cout << "Value using float cast = " << size_t(float(std::log(64)) / float(std::log(4))) << std::endl; std::cout << "Value using no data type = " << size_t(std::log(64.0) / std::log(4.0)); return 0; }
