If you do not specify any options when you invoke the Intel® C++ Compiler, the compiler performs the following:
produces an executable file
invokes options specified in a configuration file first
invokes options specified in the CL environment variable
searches for header files in known locations
sets 16 bytes as the strictest alignment constraint for structures
displays error and warning messages
uses ANSI with extensions
performs standard optimizations
on operating systems that support characters in Unicode* (multi-byte) format, the compiler will process file names containing these characters
