下面程序编译时发现ma[3]＝9错误，其原因是 【11】 。# include＜iostream. h＞class FunArray{ int *pa; //指向一个数组空间 int size; //数组元素个数public: FunArray(int a[ ], int thesize): pa(A) , size(thesize) { } int Size( ){return size;} }};void main( ){ int s[ ]={3,7,2,1,5,4}; FunArray ma (s, sizeof (s)/sizeof(int) ); ma[3] = 9 cout＜＜ma[3]＜＜end1；}
