int **x;
x = new int*[n];
for (int i = 0; i < n; i++){
x[i] = new int[m];This algorithm will create a m*n matrix. x= new int*[n] is same as allocating array of n which will be of (Int *) type. It will store the address of n arrays of m size. x[i]= new int[m] here we are allocating an array of m int. And assigning the address of each array to memory allocated above. Please let me know if I am wrong.
