struct discrb { char elem; float x; float y; float z;};typedef struct discrb *g;g= (struct discrb *)calloc(6, sizeof(struct discrb));用dev-c++ 编译器保存，在最后面一行提示：parse error before `=' token问如何修改

#include "stdio.h"void main(){typedef struct discrb //typedef 用错地方了{ char elem; float x; float y; float z; }; struct discrb *g; g= (struct discrb *)calloc(6, sizeof(struct discrb)); }
