Near the end of that function you take the address of that local variable, you for some reason store it in a pointer, and then you return that pointer. Depending upon the application, we use either adjacency list or adjacency matrix but most of the time people prefer using adjacency list over adjacency matrix. In this matrix, only 10 spaces are filled with nonzero values and remaining spaces of the matrix are filled with zero.

For each matrix team or subgroup, there is one functional. Arrays allow to define type of variables that can hold several data items of the same kind. A suggested data structure to implement the above is given by two structs, node and matrix. There are lesser nonzero elements than zeros and thus lesser memory can be used to store.
