Question

请教一段c语言的程序

typedef struct { float x,y,z; } vector;
typedef struct { double x,y,z; } dvector;
static inline vector plus( vector i, vector j )
{
vector sum;
sum.x = i.x + j.x;
sum.y = i.y + j.y;
sum.z = i.z + j.z;
return sum;
}
以上是别人写的程序，在头文件中（他好像在linux上运行成功过，我用的os是xp）。我用vc++6.0编译时，提示我
error C2085: expected '(' to follow 'inline'
error C2085: 'plus' : not in formal parameter list
请高手指点！必定重谢！

Answer 1

不用改代码，直接改project->[setting]->[c/c++]->Preprocessor definitions:编辑框里输入inline=__inline即可
因为你的inline编译器不认识，还有或者改成_inline也是可以的

Answer 2

static inline vector plus( vector i, vector j )
{
vector sum;
sum.x = i.x + j.x;
sum.y = i.y + j.y;
sum.z = i.z + j.z;
return sum;
}
STL的Vector不是这样用的

Answer 3

typedef struct { float x,y,z; } vector;
typedef struct { double x,y,z; } dvector;
static vector plus( vector i, vector j )
{
vector sum;
sum.x = i.x + j.x;
sum.y = i.y + j.y;
sum.z = i.z + j.z;
return sum;
}
