#define vect std::vector - ok?
-
I am using
std::vectorin my project. Later on, however, this will change intocsr::vector, a container defined in namespace csr that implements the same functions etc. I am writingstd::vectoreverywhere in my code and I was wondering if I could do something like this#define vect std::vector
use
vectin the code and change only the#definewhen I have to switch tocsrtype of vector. Could this cause any issues?? -

usingdirective for the purpose:using std::vector;
...
vector v;

// stdafx.h
//...
#ifdef USE_STD_VECTOR
#include <vector>
using std::vector;
#else
#include "csr_vector.h"
using csr::vector;
#endif
//...This allows you to set different Project Configurations in MS Visual Studio terminology: Win32 Std Debug, Win32 CSR Debug, etc ... differing by defining (or not)
USE_STD_VECTORat configuration level. cheers, ARWhen the wise (person) points at the moon the fool looks at the finger (Chinese proverb)

std::vectorwithcsr::vectoryou could simply usevectoreverywhere instead ofstd::vector. When including the header file you could then write -#include using namespace std;
Then when you're switching to the other namespace you simple change that to -
#include using namespace csr;
By the way, why are you planning to not use
std::vector?«_Superman_» _I love work. It gives me something to do between weekends.

#ifdef USE_STD_VECTOR
typedef std::vector vector;
#else /* ! defined(USE_STD_VECTOR) */
typedef csr::vector vector;
#endif /* USE_STD_VECTOR */then everywhere you used std::vector you just use vector. Cheers
