Random maze generator in C

Random maze generator in C

I don’t know how to make sure that a random maze can lead from the entrance on the right side to the exit on the left side without any wall blocking the path. This is my code that I am still doing. Can everyone give me a hint or algorithm to achieve a simple maze (input / output)? Thank! P / S my problem is that the maze generator does not provide a way out ... (stuck)

#include <stdio.h>
#include <time.h>
#include <stdlib.h>

#define SIZE 12
void mazeGenerator(char [][SIZE]);

int main(void)
{
    char maze[SIZE][SIZE];
    srand((unsigned int)time(NULL));
    mazeGenerator(maze);
    return 0;
}
void mazeGenerator(char a[SIZE][SIZE])
{
    size_t row,column = 0, r;

    // initialize '#' to all positions of left-hand wall
    for ( row = 0; row < SIZE; ++row )
    {
        a[row][column] = '#';
    }
    // initialize '#' to all positions of left-hand wall
    for ( row = 0; row < SIZE; ++row )
    {
        a[row][SIZE - 1] = '#';
    }

    // initialize '.' to left-hand wall random positions from 1 -> 10
    row = rand() % 11 + 1;
    a[row][0] = '.';

    // initialize '.' to right-hand wall random positions from 1 -> 10
    row = rand() % 11 + 1;
    a[row][SIZE - 1] = '.';

    // intialize '#' to all positions of top maze
    for (column = 1; column < SIZE - 1; ++column)
    {
        a[0][column] = '#';
    }

    // intialize '#' to all positions of bottom maze
    for (column = 1; column < SIZE - 1; ++column)
    {
        a[SIZE - 1][column] = '#';
    }

    // print maze
    puts("");
    puts("** Maze Generator by Huy Le **\n");
    for (row = 0; row < SIZE; ++row)
    {
        for (column = 0; column < SIZE; ++column)
        {
            printf_s("%2c",a[row][column]);
        }
        puts("");
    }
    puts("");
}
