方法二:void GetMemory2(char **p)变为二级指针.
void GetMemory2(char **p, int num) { *p = (char *)malloc(sizeof(char) * num); }

35.程序改错
class mml { private: static unsigned int x; public: mml(){ x++; } mml(static unsigned int &) {x++;} ~mml{x--;} pulic: virtual mon() {} = 0; static unsigned int mmc(){return x;} ...... }; class nnl:public mml { private: static unsigned int y; public: nnl(){ x++; } nnl(static unsigned int &) {x++;} ~nnl{x--;} public: virtual mon() {}; static unsigned int nnc(){return y;} ...... };
