Answer: While constructing a function the parameters can be passed by value or by reference.
In value parameter we actual make a copy of the values which has been passed to the function from the main method while we reference parameter we copy the address of the values in memory so that while our program references those values it it can refer them from their memory location.
Explanation:
Now we take can example to show parameter passing by value and reference with the help of an C program to add two numbers
int add_val(int x, int y) {
return x + y;
}
void add_ref(int *x, int y) {
*x += y;
}
int main () {
int a, b, c, d;
a = 2;
b = 1;
c = add_val(a,b); //value parameter
d = add_ref(&a, c); // reference parameter
return 0;
}
In the above code the value the value of c is 3 and the value of d is 5. In add_p we have passed the address of the a but in add_val we have passed the values of a and b.
Answer:
The result of combining the both tables is:
Employee(EmployeeNum, LastName, FirstName, WageRate, SocSecNum, DepartmentNum, Street, City, State, PostalCode)
Explanation:
Since the EmployeeNum is the primary and it is available in both tables, what happens is that, it will not list the primary key column twice. It will list the primary key first then all the other attribute in the first table followed by the attribute in the second table. And it will take note so as not to repeat attribute that already occur in the first table.
For instance; in this case, besides EmployeeNum, LastName and FirstName also appear in the both tables but only one instance of them were listed in the resulting table.

<u>Explanation:</u>
On the off chance that you need to add a header or footer to all sheets, select each sheet by right-clicking one of the sheet tabs at the base of the Excel screen and clicking "Select All Sheets" in the spring up menu. It's genuinely basic to put an Excel header on all pages of all worksheets in your record.
A header is a line of content that shows up at the highest point of each page of a printed worksheet. You can change the direction of a worksheet, which is the situation of the substance with the goal that it prints either vertically or on a level plane on a page.
