Segmentation fault / multidimansional arrays

[illyaSlobozhanin]

Hi all. I've got a problem during creating 2-dimensional array.

Graph::Graph(){
    vertexList = new Vertex[MAX_VERTS];

    adjMat = new int*[MAX_VERTS]; // int** adjMat;
    for(int i(0); i < MAX_VERTS; i++){ //const int MAX_VERTS = 10;
        adjMat[MAX_VERTS] = new int[MAX_VERTS];
    }

    for(int i(0); i < MAX_VERTS; i++)
        for(int j(0); j < MAX_VERTS; j++)
            adjMat[i][j] = 0; //sigmentation fault here

    nVerts = 0;
}

qt 5.5.1, gcc compiler.

Hi and welcome to devnet,

Nothing Qt specific here, look again at your for loop, you are initializing the same value over and over.

Yes, exactly as SGaist says above, try changing

adjMat[MAX_VERTS] = new int[MAX_VERTS];

to

adjMat[i] = new int[MAX_VERTS];

@SGaist thanks a lot=)
