Win32控制台项目问题

Question

I created a Win32 Console project (disabled "precompiled header" option) with my VS2010.

Then I filled the code as below

#include <stdio.h>
int main (void) {
    double d = 0x0.3p10;
    printf ("%.f\n", d);
    return 0;
}

The compiler shows a syntax error on the line of double d = 0x0.3p10; .

: error C2059: syntax error : 'bad suffix on number'
: error C2143: syntax error : missing ';' before 'constant'
: error C2146: syntax error : missing ';' before identifier 'p10'
: error C2065: 'p10' : undeclared identifier

Is there something wrong on my project configuration?

No. Microsoft Visual C++ doesn't support ISO C99. Sorry. There is no workaround except to use a different compiler. See this question's accepted answer .

Alternatives:

1. Clang which will work with the MSVC headers. I don't think there are binaries available for it yet though so unless you like compiling compilers...
2. mingw which comes with msys and a complete set of headers of its own for the w32api.
3. Intel's Compiler Suite . This integrates with Visual Studio but is non-free.
