Consider the following program written in C syntax:

void fun (int first, int second) {
first += first;
second += second;
} void main() {
int list[2] = {1, 3};
fun(list[0], list[1]);
}

For each of the following parameter-passing methods, what are the values of the list array after execution?
a. Passed by value
b. Passed by reference
c. Passed by value-result

Answer

1. Passed by value

list[0] = 1 and list[1] = 3

2. Passed by reference

list[0] = 2 and list[1] = 6

3. Passed by value-effect

list[0] = 2 and list[1] = 6

Explanation:

From the code segment above, the points to be noted are

1. An integer array list is declared

2. list is declared to accept only two integer values

3. list[0] = 1

4. list[1] = 3

For pass by value;

None of the actual arguments are changed, so the variables retain the values they were initialized with.

So,

list[0] = 1 and list[1] = 3

Passed by reference

With pass by reference, the arguments are changed.

Given that

list[0] = 1

list[1] = 3

The value of list[0] and list[1] are incremented by their respective original value, as follows

list[0] = 1 + 1 = 2

list[1] = 3 + 3 = 6

So, the new values becomes

list[0] = 2

list[1] = 6

3. Passed by value-effect

The passed by, value-result has the same effect as reference.

i just did so your welcome!

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
