Dynamic Allocation of Arrays

In C one can dynamically allocate arrays

      int n = 10;
      float *x = (float *) malloc ( n*sizeof(float) );

Or

      int n = 10;
      float *x;
      x = (float *) malloc ( n*sizeof(float) );

• (float *) forces a pointer to float

• note the use of the sizeof function

• note the use of variable n

To delete a dynamically allocated array use the free function

      free (x);
