Answer:
void doublelt(int *number)
{
*number=*number*2;
}
Explanation:
This exercise is for you to learn and understand the PASS BY POINTER syntax. The importance of this is that if you didnt use a pointer you would have to RETURN an int from the function. in that case the code would be:
int doublelt(int number)
{
number=number*2;
return number;
}
Passing by pointer manipulates the value by going inside the memory and where it resides. Without the pointer, the function would create COPIES of the argument you pass and delete them once the function ends. And you would have to use the RETURNED value only.

Explanation:
This is a really good question! WiFi signal strengths depend on the model of the WiFi receiver (which is in the iPhone) and the quality of the router sending out the signals.
We call it
functional dependencies.
A functional dependency which is also commonly known as a
database dependency occurs in a database when info stored in the same database
determines other information stored in the same table. Knowing the value of a
set of attribute is enough to tell you the value of another set of attributes.
