Answer:

Explanation:

#include <iostream>

using namespace std;

int* append(int*,int,int*,int);

int* merge(int*,int,int*,int);

void print(int*,int);

int main()

{ int a[] = {11,33,55,77,99};

int b[] = {22,44,66,88};

print(a,5);

print(b,4);

int* c = append(a,5,b,4); // c points to the appended array=

print(c,9);

int* d = merge(a,5,b,4);

print(d,9);

}

void print(int* a, int n)

{ cout << "{" << a[0];

for (int i=1; i<n; i++)

cout << "," << a[i];

cout << "}\n";

}

int* append(int* a, int m, int* b, int n)

{

int * p= (int *)malloc(sizeof(int)*(m+n));

int i,index=0;

for(i=0;i<m;i++)

p[index++]=a[i];

for(i=0;i<n;i++)

p[index++]=b[i];

return p;

}

int* merge(int* a, int m, int* b, int n)

{

int i, j, k;

j = k = 0;

int *mergeRes = (int *)malloc(sizeof(int)*(m+n));

for (i = 0; i < m + n;) {

if (j < m && k < n) {

if (a[j] < b[k]) {

mergeRes[i] = a[j];

j++;

}

else {

mergeRes[i] = b[k];

k++;

}

i++;

}

// copying remaining elements from the b

else if (j == m) {

for (; i < m + n;) {

mergeRes[i] = b[k];

k++;

i++;

}

// copying remaining elements from the a

else {

for (; i < m + n;) {

mergeRes[i] = a[j];

j++;

i++;

}

return mergeRes;

Initialize a list. ACTIVITY Initialize the list short.names with strings 'Gus', Bob, and 'Ann'. Sample output for the given prog

Ksenya-84 [330]

Answer:

shortNames = ['Gus', 'Bob','Zoe']

Explanation:

In this assignment, your knowledge of list is been tested. A list is data structure type in python that can hold different elements (items) of different type. The general syntax of a list is

listName = [item1, "item2", item3]

listName refers to the name of the list variable, this is followed by a pair of square brackets, inside the square brackets we have items separated by commas. This is a declaration and initialization of a list with some elements.

The complete python code snippet for this assignment is given below:

shortNames = ['Gus', 'Bob','Zoe']

print(shortNames[0])

print(shortNames[1])

print(shortNames[2])

In a virtual memory system, each process must have its own page table.(True or False?)

Anna71 [15]

Answer: True

Explanation:

Virtual memory is the secondary storage memory and this type of memory are addressed as main part of the memory.

When the virtual memory copying in the physical memory then, at that time the operating system divide the memory into the file page with the address and definite size number. Then, the each page are store in a disk.

When this page are required then, the operating system copy from disk to main memory and then, the virtual address are converted into the real address.

Write a program that reads a list of integers, and outputs the two smallest integers in the list, in ascending order. The input

kompoz [17]

Answer:

Following are the program in the C++ programming Language.

//header files

#include <iostream>

#include <vector>

using namespace std;//name space

// define main method

int main()

{

//set integer variables

int size, num;

//get input the size of the list

cout<<"Enter size of list: ";

cin >> size;

//set integer type vector variable

vector<int> vecs;

//Set the for loop

for (int index = 0; index < size; ++index)

{//get elements of the list from the user

cout<<" :";

cin >> num;

//push back the elements of the list

vecs.push_back(num);

}

//storing the first two elements in variable

int n = vecs[0], n1 = vecs[1], current , temp;

//set if conditional statement

if (n > n1)

{

//perform swapping

temp = n;

n = n1;

n1 = temp;

}

//Set for loop

for (int index = 2; index < size; ++index)

{

//store the value of the vector in the variable

current = vecs[index];

//set if conditional statement

if (current < n)

{

//interchange the elements of the variable

n1 = n;

n = current;

}

else if(current < n1)

{

n1 = current;

}

//print the value of first two smallest number.

cout <<"\n" <<n << " " << n1 << endl;

return 0;

}

Output:

Enter size of list: 5

:10

:21

2 3

Explanation:

Here, we define the required header files and namespace then, we define "main()" function inside the main function.

Set two integer data type variable "size", "num".
Print message and get input from the user in variable "size".
Then, we set integer vector type variable "vecs".
Set the for loop to get the number of input in the variable "num" from user.
Then, we push back the elements of the list and store first two elements of the list in the variable "n", "n1".
Set the conditional statement to perform swapping.

Define the for loop to store the list of the vector in the integer type variable "current".
Finally, we print the value of the two smallest numbers of the list.
