warning C4047: 'initializing' : 'char *' differs in levels of indirection from 'const int '

以下来自MSDN

编译器警告（等级 1）C4047

错误消息

“operator”:“identifier1”与“identifier2”的间接寻址级别不同

指针可指向变量（一级间接寻址），指向另一个指向变量的指针（二级间接寻址）等。

示例

下面的示例生成 C4047：

// C4047.c// compile with: /W1int main() {   char **p = 0;   // two levels of indirection   char *q = 0;   // one level of indirection   char *p2 = 0;   // one level of indirection   char *q2 = 0;   // one level of indirection   p = q;   // C4047   p2 = q2;}

下面的示例生成 C4047：

// C4047b.c// compile with: /W1#include int main() {   int i;   FILE *myFile = NULL;   errno_t  err = 0;   char file_name[256];   char *cs = 0;   err = fopen_s(&myFile, "C4047.txt", "r");   if ((err != 0) || (myFile)) {      printf_s("fopen_s failed!/n");      exit(-1);    }   i = fgets(file_name, 256, myFile);   // C4047   cs = fgets(file_name, 256, myFile);   // OK
