you are unsure how they work, use the debugger to walk through them line by line (we will cover how to do that in the appendix). Also, you can learn a lot by modifying the examples and recompiling them to see what happens. However, the best way to learn is to write yourown program utilizing the...

criterion. As you have already seen, you can use inline to deﬁne yourownfunctions. In many situations, however, it is more convenient to deﬁne a functionusing an M-ﬁle instead of an inline function. Let us return to the problem described above, where we computed some values of sin(x)/x with x = 10−b...

variables with local and global scope:
Example
In the example above there are two variables $x and $y and a function myTest(). $x
is a global variable since it is declared outside the function and $y is a local
variable since it is created inside the function.
When we output the values of the two...
