4. double and float array type    cboard.cprogramming.com

A double is larger than a float, so needs a different format for scanf() - it is rather critical that scanf() know the actual size of the variable being read. %f is for float. This needs to be modified with a l (letter L) prefix for double (i.e. %lf). The prefix is also need for other floating point formats (%e versus ...

10. Arrays and floats issues.    forums.devshed.com

You have a couple of arrays of longs (if you can consider a single element an array). You have an array of float pointers which you are stuffing with long pointers. You have an int pointer which you are stuffing with a pointer to one element of the float pointer array, which actually contains long pointers. What's up with that?

11. Append/ Concat Array of floats    forums.devshed.com

Arrays are not resizable, so the destination array needs to be large enough for both sets of data regardless of whether you are appending to concatenating. There is nothing special here, nor no magic function (execpt one you might write yourself); you simply iteratively assign each element in turn to the destination, or you could use memcpy() or memmove(). So to ...
