Question

Can you please answer this in complete C++ program.

I. Write a program that reads in an array of five integers al 5] and arses the mray in t fncion largest that rcurns the value of the largest element in the arrav, 2.Write a program that reads in two arrays, a[3] and b[3], and passes them to a function Scalarproduct that returns the scalar product of these arrays; the scalar product of two arrays is

Answer 1

Question 1:

Here is code:

#include <iostream>

#include <limits>

using namespace std;

int largest(int *array, int SIZE)

{

// set initial default larger data array first element

int larger = array[0];

// loop from 1 to size

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

{

// checking if current element is larger

if (larger < array[i])

larger = array[i];

}

return larger;

}

int main()

{

const int SIZE = 5;

int a[SIZE];

cout << "Enter " << SIZE << " values : " << endl;

// loop from 0 to size and read user input

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

{

cout << "Enter values " << (i + 1) << "# : ";

// check if input is valid or not

while (!(cin >> a[i]))

{

// flush the cin data

cin.clear();

cin.ignore(numeric_limits<streamsize>::max(), '\n');

cout << "Invalid entery, Try again : ";

}

}

int result = largest(a, SIZE);

cout << "The largest value in array : " << result << endl;

return 0;

}

Output:

Enter 5 values: Enter values 1#: 5 Enter values 2# : 9 Enter values 3# : 7 Enter values : 5 Enter values 5#: 1 The largest value in array 9

Question 2:

Here is code:

#include <iostream>

#include <limits>

using namespace std;

int Scalarproduct(int *a, int *b, int SIZE)

{

int scalar = 0;

// loop from 0 to size

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

{

// product the number of individual index

scalar += a[i] * b[i];

}

return scalar;

}

int main()

{

const int SIZE = 3;

int a[SIZE], b[SIZE];

cout << "Enter " << SIZE << " values : " << endl;

// loop from 0 to size and read user input

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

{

cout << "Enter values a : " << (i + 1) << "# : ";

// check if input is valid or not

while (!(cin >> a[i]))

{

// flush the cin data

cin.clear();

cin.ignore(numeric_limits<streamsize>::max(), '\n');

cout << "Invalid entery, Try again : ";

}

}

// loop from 0 to size and read user input

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

{

cout << "Enter values b : " << (i + 1) << "# : ";

// check if input is valid or not

while (!(cin >> b[i]))

{

// flush the cin data

cin.clear();

cin.ignore(numeric_limits<streamsize>::max(), '\n');

cout << "Invalid entery, Try again : ";

}

}

int result = Scalarproduct(a, b, SIZE);

cout << "The largest value in array : " << result << endl;

return 0;

}

Output:

Enter 3 values: Enter values a : 1# : 1 Enter values a : 2# : 2 Enter values a : 3# : 1 Enter values b : 1# : 1 Enter values b : 2# : 2 Enter values b : 3# : 1 The largest value in array 6
