用C++写一个小程序,要求写出完整的代码,设计程序解决迷宫问题,该程序使用两个栈,一个栈用来初始化迷宫问题, 另一个用来实现回溯.在用户输入迷宫,一次输入一行.用户输入的迷宫包括任意个行和任意个列.按照用户输入的顺序将行数据放入栈mazeRows中.第二个栈mazeStack在走出迷宫的过程中使用,需要将当前位置为尝试过的临近位置存放到栈中.

以下是使用 C 语言解决迷宫问题的代码示例:
```
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
#include <string.h>
#define STACK_SIZE 100
typedef struct {
int row;
int col;
} Position;
typedef struct {
Position data[STACK_SIZE];
int top;
} Stack;
void initStack(Stack* stack) {
stack->top = -1;
}
bool isStackEmpty(Stack* stack) {
return stack->top == -1;
}
bool isStackFull(Stack* stack) {
return stack->top == STACK_SIZE - 1;
}
void push(Stack* stack, Position element) {
if (isStackFull(stack)) {
printf("栈已满\n");
return;
}
stack->data[++stack->top] = element;
}
Position pop(Stack* stack) {
if (isStackEmpty(stack)) {
printf("栈已空\n");
return (Position){-1, -1};
}
return stack->data[stack->top--];
}
// 判断当前位置是否在边界内
bool isInBound(int row, int col, int numRows, int numCols) {
return row >= 0 && row < numRows && col >= 0 && col < numCols;
}
// 判断当前位置是否是障碍
bool isBarrier(char** maze, int row, int col, int numRows, int numCols) {
return !isInBound(row, col, numRows, numCols) || maze[row][col] == '#';
}
// 判断当前位置是否是出口
bool isExit(char** maze, int row, int col, int numRows, int numCols) {
return isInBound(row, col, numRows, numCols) && maze[row][col] == 'E';
}
// 在迷宫中搜索路径
bool searchPath(char** maze, int row, int col, int numRows, int numCols,
Stack* mazeStack) {
// 将当前位置压入栈中
push(mazeStack, (Position){row, col});
// 如果当前位置是出口,则搜索成功
if (isExit(maze, row, col, numRows, numCols)) {
return true;
}
// 尝试向上走
if (!isBarrier(
