C++运行问题：The variable 'Data' is being used without being initialized.
for ( int i = 0 ; i < NUI_SKELETON_COUNT; i++ )//处理骨骼ID信息
{
//
.
我把
NUI_SKELETON_DATA Data;
int HandRightX;
放大for前面还是出现这个现象.求大侠帮忙,追加100分.VS2010
Run-Time Check Failure #3 - The variable 'Data' is being used without being initialized.

NUI_SKELETON_DATA Data;//这里没初始化
memset(&Data,0,sizeof(NUI_SKELETON_DATA));
//你这里应该还有一个赋值过程.因为你下面用到了Data
//SkeletonFrame.SkeletonData[i] 这里的 SkeletonData[i] 应该是一个NUI_SKELETON_DATA结构吧?
其实你上面没必要建一个Data 直接用SkeletonFrame.SkeletonData[i]
int HandRightX;
HandRightX = SkeletonFrame.SkeletonData[i].SkeletonPositions[NUI_SKELETON_POSITION_HAND_RIGHT].x;
再问：如果我想调出HandRightX的值，用调试OutputDebugString怎么调用？

C++运行问题：The variable 'Data' is being used without being init the variable'discount' is being used without being initializ The variable 'sele' is being used without being initialized. 程序出错：The variable 'y' is being used without being initialize varible is being used without being initialized ,Run-Time Check Failure #3 - The variable 'L' is being used Run-Time Check Failure #3 - The variable 'r' is being used w The username chosen is already being used. the movie data is being downloaded是什么意思这里为什么用being without being the key is already being used by another computer The computer being used by them is very fast.
