为啥结果不一样？

我怀疑是这里有问题:
index = 0;
if(nLen > 1)
{
char cTemp[4] = {0};
int n = 0;
for(int j = strlen(szStr)-1;j >=0 ;--j)
{
cTemp[n] = szStr[j];
++n;
}
sz_num[i] = cTemp;

}
但错在哪里啊，好像没错？

顶

[goodname]

感觉应该
strcpy(sz_num[i],cTemp);

眼花缭乱……

它是一个sz_num指针数组,strcpy肯定不行啊,兄弟

[goodname]

但是你试图将一个局部的数组指针，给他也是错误的。

要么你只能在此地动态分配出来。
sz_num[i] = malloc(4);
strcpy(sz_num[i],cTemp);

谢谢楼上的，嗯

哈哈，问题解决了,哎。。。。。。。。

[cccbuiler]

问题解决，有什么结论呢？是哪里的问题呢？
