Question

C++ Problems:

1. Write a program that reads in an array of user given size n and then it reads several increment values terminated by 0. The program calls each time a function incarray() that accepts an array A, its size S and an increment value inc and updates yje array by incrementing all its values by the passed value of inc. The program prints out the array after each update.

2. write a program that reads in a n array of user given size N and then sorts the array either in ascending or descending order depending on a user defined character input AD (AD='A' for ascending and AD='D' for descending)

Answer 1

Question 1:

Here is code:

#include <iostream>

using namespace std;

int *incarray(int *arr, int newEle, int size)

{

int *newArr = (int *)malloc(sizeof(int) * (size + 1));

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

{

newArr[i] = arr[i];

}

newArr[size] = newEle;

return newArr;

}

int main()

{

int *array, num, size = 0;

while (true)

{

cout << "Enter number : ";

cin >> num;

if (num == 0)

break;

array = incarray(array, num, size);

size++;

}

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

{

cout << array[i] << " ";

}

cout << endl;

return 0;

}

Output:

Enter number :2 Enter number 3 Enter number 4 Enter number 6 Enter number:7 Enter number 8 Enter number 9 Enter number e 2 3 4 6789

Question 2:

Here is code:

#include <iostream>

using namespace std;

void sortArray(int *array, int size, char type)

{

int i, j, temp;

if (type == 'A')

{

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

{

for (j = i + 1; j < size; j++)

{

if (array[i] > array[j])

{

temp = array[i];

array[i] = array[j];

array[j] = temp;

}

}

}

}

if (type == 'D')

{

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

{

for (j = i + 1; j < size; j++)

{

if (array[i] < array[j])

{

temp = array[i];

array[i] = array[j];

array[j] = temp;

}

}

}

}

}

int main()

{

int *array, num, size = 0;

while (true)

{

cout << "Enter number : ";

cin >> num;

if (num == 0)

break;

array = incarray(array, num, size);

size++;

}

sortArray(array, size, 'D');

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

{

cout << array[i] << " ";

}

cout << endl;

return 0;

}

Output:

Enter number : 5 Enter number 6 Enter number : 1 Enter number :2 Enter number :9 Enter number : 7 987654 21
