I read somewhere that Intel C++ is free for non-professional use. But the intel site www.software.intel.com has no option for free download. It provides the 30 days trial version and need to buy license key or further use. Does anyone has the knowledge about this?if yes please provide the link to download free version.
Intel provides a 30 day free evaluation of their products including the ICC Compilers. You can avail this from the following website Intel official website for Intel C and C++ Compiler
The compiler is not available as a lone product. It comes as a part of either one of the following products of Intel.
