A:
Change
int K[]= new int[Vertices->total];
to
int *K = new int[Vertices->total];
The 1st one is the Java way of creating an array, where you K is a reference to an integer array. But in C++ we need to make K a pointer to integer type.

@shiva Almost. Arrays in c are really just pointers to blocks of memory. so, if you want to use K to manipulate an array of array of integer, the declaration would be `int K** = new int*[<count_of_subarrays];´In the following , you would have to initialize each element of K with `K[i] = new int[<count_of_values>´

A:
new int[Vertices->total] returns a pointer and hence, int *K = new int[Vertices->total]; should work fine.
If you know the size of Vertices->total at compile time ( ie CONSTANT) then you could have used
int K[Vertices->total]; // Allocates the memory on stack
