Thread: Help with arrays and pointers please...

To get you started the prototype of such a function would be like this:

Code:

addarrays(float *array1ptr, float *array2ptr, float *array3ptr, unsigned int Size);

adds the contents of the first two arrays together, element by element; and places the results in the third array before returning.

something like this

Code:

while(size!=0)
{
   *array3ptr= *array1ptr+*array2ptr;
   array1ptr++;
   array2ptr++;
   array3ptr++;
  Size--;
}
