Answer:
The c++ function for reversing an array is given. The function is declared void since it returns no value.
void reverse( int arr[], int len )
{
int temp[len];
for( int k = 0; k < len; k++ )
{
temp[k] = arr[k];
}
for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )
{
arr[k] = temp[j];
}
}
Explanation:
The reverse function uses another array to reverse the elements of the original array.
An integer array is declared, temp[len], having the same length as the input array.
int temp[len];
To begin with, the elements of the input array are copied in the temp array.
for(int k = 0; k < len; k++ )
{
temp[k] = arr[k];
}
Next, the elements of the input array are given new value.
The temp array, in reverse order, is copied into the input array.
for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )
{
arr[k] = temp[j];
}
The above for loop makes use of two variables simultaneously.
While the array, arr is proceeding from first element to the next, the array temp begins with the last element and goes down to the previous element.
Now, the input array, arr, contains the elements in reverse order.
The complete program is given.
#include <iostream>
using namespace std;
void reverse( int arr[], int len );
void reverse( int arr[], int len )
{
int temp[len];
for(int k = 0; k < len; k++ )
{
temp[k] = arr[k];
}
for( int k = 0, j = len-1; k < len, j>= 0; k++, j-- )
{
arr[k] = temp[j];
}
}
int main()
{
int len = 5;
int arri[len];
for( int l = 0; l < len; l++ )
{
arri[l] = l;
}
reverse( arri, len );
return 0;
}

what is computers machain?
Answer:
the electronic device which take data process it and give meaningful results is called computer machine
Consider the following program written in C syntax:
void swap(int a, int b) {
int temp;
temp = a;
a = b;
b = temp;
} void main() { int value = 2, list[5] = {1, 3, 5, 7, 9};
swap(value, list[0]);
swap(list[0], list[1]);
swap(value, list[value]);
}
For each of the following parameter-passing methods, what are all of the
values of the variables value and list after each of the three calls to
swap?
1. Passed by value
2. Passed by reference
3. Passed by value-result
6.
The values of the variables value and list after each of the three calls to
swap are:
value = 2 and list[5] = {1, 3, 5, 7, 9};value = 2 and list[5] = {3, 1, 5, 7, 9};value = 2 and list[5] = {3, 1, 5, 7, 9};How to determine the values of variable value and the list?1. Passed by value
In this case, the values of the actual arguments remain unchanged; So the variable value and the list would retain their initial values
The end result is:
value = 2 and list[5] = {1, 3, 5, 7, 9};
2. Passed by reference
With pass by reference, the arguments are changed.
Given that
value = 2 and list[5] = {1, 3, 5, 7, 9};
The value of variable value is swapped with list[0].
So, we have:
value = 1 and list[5] = {2, 3, 5, 7, 9};
Then list[0] and list[1] are swapped
So, we have:
value = 1 and list[5] = {3, 2, 5, 7, 9};
Lastly, value and list[value] are swapped
So, we have:
value = 2 and list[5] = {3, 1, 5, 7, 9};
The end result is:
value = 2 and list[5] = {3, 1, 5, 7, 9};
3. Passed by value-result
Since there is no loop in the program, the pass by value-result has the same output as the pass by reference.
So, the end result is:
value = 2 and list[5] = {3, 1, 5, 7, 9};

What is the Trunc function in Delphi?When you look at the Delphi code, the Trunc function is known to be a fuction that reduces or cut off a real-type value and make it into an integer-type value.
Note that X is a real-type expression and so the Trunc is said to often brings back an Int64 value that is meaning the value of X approximated to zero and when the cut of value of X is not found in the Int64 range, an EInvalidOp exception is brought up.

9.12: Element Shifter
Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is one element larger than the argument array. The first element of the new array should be set to 0. Element 0 of the argument array should be copied to element 1 of the new array, element 1 of the argument array should be copied to element 2 of the new array, and so forth. The function should return a pointer to the new array. Demonstrate the function by using it in a main program that reads an integer N (that is not more than 50) from standard input and then reads N integers from a file named data into an array. The program then passes the array to your element shifter function, and prints the values of the new expanded and shifted array on standard output, one value per line. You may assume that the file data has at least N values.
Prompts And Output Labels. There are no prompts for the integer and no labels for the reversed array that is printed out.
Input Validation. If the integer read in from standard input exceeds 50 or is less than 0 the program terminates silently.
