填空题

假定从键盘上输入一批整数，依次为： 78 63 45 30 91 34 –1，请写出该算法的 输出结果。

< include < iostream. h>

< include < stdlib. h >

consst int stackmaxsize = 30;

typedef intelemtype;

struct stack {

elemtype stack [stackmaxsize];

int top;

};

< include “stack. h”

void main ( )

{

stack a;

initstack(a);

int x;

cin >>x;

while (x! = -1) {

push (a, x );

cin >>x;

}

while (!stackempty (a))

cout <<pop (a) <<”” ;

cout <<end1;

}
