Status Getstack(SqStack &S, SElemType e){ // 改&e 为：e, 这就允许你用常数调用。main(){ SqStack S; // 改&S 为 S if(S.top==S.base) exit(0); // 改掉 返回 return ERROR; 例如用 exit(0); 因为 void 函数体内 不能用 return 语句。

So the results go to the user that way, not through the function return value. You could change your program so the function return type were void, meaning the function does not return a value, and the program would still work. In other programs, a function may return a value t...
