San*_*uuu 1 c++ command-line-arguments
我用c ++编写了一个程序,它应该采用几个命令行参数,第一个是整数,其余三个是浮点数.处理它的代码部分看起来像这样:
_tmain(__in int argc, __in PZPWSTR argv)
{
USHORT X, Y, Z, ZR, XR; // Position of several axes
JOYSTICK_POSITION iReport; // The structure that holds the full position data
BYTE id=1; // ID of the target vjoy device (Default is 1)
UINT iInterface=1; // Default target vJoy device
BOOL ContinuousPOV=FALSE; // Continuous POV hat (or 4-direction POV Hat)
int count=0;
DOUBLE Xr, Yr, Zr;
// Get the ID of the target vJoy device
if (argc>1 && wcslen(argv[1]))
sscanf_s((char *)(argv[1]), "%d", &iInterface);
sscanf_s((char *)(argv[2]), "%d", &Xr);
sscanf_s((char *)(argv[3]), "%d", &Yr);
sscanf_s((char *)(argv[4]), "%d", &Zr);
_tprintf("Acquired: X %d\nY %d\nZ %d\n", Xr, Yr, Zr);
the rest of the code ...}

我的问题是,当我通过写入命令行调用程序时
name.exe 1 15 16 17

我得到Xr = 15但是Zr = 16而Yr只是一些看似随机的巨大负数.
我知道这可能是一个非常基本的错误,但我无法找到它是什么.谢谢你的任何建议.
