我想为用户输入的每个字符分配一个指针。然后在这样做时,我可能可以使用一个循环来存储字符,然后第二个循环使用指针重新排列堆栈顺序。但是我不知道如何以程序形式编写它,我不确定它是否可以工作。这是我到目前为止所拥有的:
#include<iostream>
using namespace std;
class Stack{
public:
enum {MaxStack = 50};
void init() {top = -1;}
void push( char n ){
if ( isFull() ) {
cerr << "Full Stack. DON'T PUSH\n";
return;
}
else {
arr[ ++top ] = n;
cout << "Just pushed " << n << endl;
return;}
}
int pop() {
if (isEmpty() ) {
cerr << "\tEmpty Stack. Don't Pop\n\n";
return 1;
}
else
return arr[top--];
}
bool isEmpty() {return top < 0 ? 1 : 0;}
bool isFull() {return top >= MaxStack -1 ? top : 0;}
void dump_stack() {
cout << "The Stack contents, from top to bottom, from a stack dump are: " << endl;
for (int i = top; i >= 0; i--)
cout << "\t\t" << arr[i] << endl;
}
private:
int top;
int arr[MaxStack];
};
int main()
{
Stack a_stack;
int x = 0;
char inputchar;
cout<<"Please enter a word"<<endl;
a_stack.init();
while (inputchar != '.') //terminating char
{
cin >> inputchar;
array[x] = inputchar;
x++;
}
int j = x;
for (int i = 0; i < j; i++)
{
cout << array[x];
x--;
}
a_stack.push();
a_stack.dump_stack();
return 0;
}
