这是一个非常非常令人讨厌的问题。我的问题是,gcc似乎没有为我的int指针分配足够的空间。
以下是代码:
fns = (int*)calloc(c,sizeof(int));
所以,之后我用一个简单的循环填充这个和0:
offset = seekToFirstParam(fnString,n);
i = 0;
while(i<c) {
tmp[i] = readNextParam(fnString,n,offset,&s);
if (isFunctionString(tmp[i])) {
fns[i] = 1;
} else {
fns[i] = 0;
}
i++;
}
所以这是一个&#34;标志&#34;数组,但是当我调试它,并打印我得到的元素:
156212102,0,0,0,1,1
或者是som。像这样。我没有得到它,因为如果在calloc方法中我写这样的1000:
fns = (int*)calloc(1000,sizeof(int));
工作正常。
好的,这是一个洞功能:
char **readFnParams(char *fnString, int n, int *count, int **func) {
char **tmp;
int *fns = NULL;
int c,i = 0,offset,s;
c = getParamsCount(fnString,n);
if (!c) {
return NULL;
}
tmp = (char**)calloc(c,sizeof(char));
fns = (int*)calloc(c,sizeof(int*));
offset = seekToFirstParam(fnString,n);
while(i<c) {
tmp[i] = readNextParam(fnString,n,offset,&s);
if (isFunctionString(tmp[i])) {
tmp[i] = readNextFunctionParam(fnString,n,offset,&s);
offset = seekToNextParam(fnString,n,offset + s - 1);
fns[i] = 1;
} else {
fns[i] = 0;
offset = seekToNextParam(fnString,n,offset);
}
i++;
}
*func = fns;
*count = c;
return tmp;
}
:)好的,这是一个孔.c文件。是的我以前的q。结束这个联系,因为它是一个功课。

输入如下: = SZORZAT(MDETERM(A1:D4),NAGY(A1:D4,0),10,20,30)
答案 0 :(得分:2)
在我看来,你没有正确分配,你有:
tmp = (char**)calloc(c,sizeof(char));
第一行tmp正在分配大小为c
的{{1}}个元素(1个字节的c个元素),我想你想要char
个大小为c
的元素( c元素大小为每个元素4或8个字节,具体取决于您是32位还是64位平台)。由于您的例程char *
正在返回readNextParam()
以存储在此数组中,因此您需要将char *
的calloc sizeof更改为:
tmp
因此,我相信当你写入流入你的其他数组的tmp = calloc(c,sizeof(char*));
数组时,你会有内存覆盖。通过制作两个“1000”元素,你已经填充了第一个tmp
,足以使覆盖仍然存在于同一块内存中。
