first steps -> How "Mazes" have been made

Yes, but I mean how to present if the cell is wall,how to walk over the matrix and mark cells have already visited, how to return and change may way
this tings.........................

well that you can define by the cell type like
typdef struct mazecell{
int type;
bool visited;
}

mazecell mymaze[10][10];

There havent easier way :(

what is hard in it? you can also create a class instead of a struct, but you need some data strcuture to describe your maze cell, if you need many information about the cell, you can also create for every information you need a matrix like:
int visited[10][10];
int type[10][10];
so i would propose the creating a class cell and making a matrix of it, since in the class you can add any property which will be add to every cell.
