The answer is : variables
When viewing data entered into a spreadsheet, the columns identify Variable. The variables later can be used on a formula to help you process any sort of data that is implemented within excels' formula system
Answer:
C code for half()
#include<stdio.h>
void half(float *pv);
int main()
{
float value=5.0; //value is initialized
printf ("Value before half: %4.1f\n", value); // Prints 5.0
half(&value); // the function call takes the address of the variable.
printf("Value after half: %4.1f\n", value); // Prints 2.5
}
void half(float *pv) //In function definition pointer pv will hold the address of variable passed.
{
*pv=*pv/2; //pointer value is accessed through * operator.
}
- This method is called call-by-reference method.
- Here when we call a function, we pass the address of the variable instead of passing the value of the variable.
- The address of “value” is passed from the “half” function within main(), then in called “half” function we store the address in float pointer ‘pv.’ Now inside the half(), we can manipulate the value pointed by pointer ‘pv’. That will reflect in the main().
- Inside half() we write *pv=*pv/2, which means the value of variable pointed by ‘pv’ will be the half of its value, so after returning from half function value of variable “value” inside main will be 2.5.

Answer:
Jen's laptop and her daughter's phone, because they are both connected to the router and turned on.
Explanation:
A network comprises of two or more interconnected devices such as computers, routers, switches, smartphones, tablets, etc. These interconnected devices avail users the ability to communicate and share documents with one another over the network.
Additionally, in order for a network to exist or be established, the devices must be turned (powered) on and interconnected either wirelessly or through a cable (wired) connection.
Hence, the computers which are currently networked are Jen's laptop and her daughter's phone, because they are both connected to the router and turned on. A smartphone is considered to be a computer because it receives data as an input and processes the input data into an output (information) that is useful to the end user.
Answer:
Pseudocode
////////////////////////////////////////////////////////////////////////////////////////////////////////////
Integer netElevation(list of elements of type elevation - type and number)
<em>function open</em>
Define running total = 0
for each element from list
<em>loop open</em>
elevation type = element[i].type
if (elevation type == Up)
running total = running total + element[i].number
else
running total = running total - element[i].number
<em>loop close</em>
return running total
<em>function close</em>
