Questions about how to generate 32-bit/64-bit programs

The generation of 32-bit/64-bit programs is not determined by the number of bits in the operating system (meaning that the generation of 32-bit systems is not necessarily 32-bit, and the same is not necessarily 64-bit generation under 64-bit), which is primarily determined by the number of bits of the compiler.

To generate a 32-bit/64-bit program, you need to select the appropriate compiler (32-bit/64-bit) in the compilation environment. Here is an example of vs2008 (generating a 64-bit program):

Open Configuration Manager in the solution, click on select New Solution Platform, select x64 platform, compile build is ready. If you do not have this option, you need to install the appropriate x64 compiler
