Question

cout << "Part 1" << endl; // Part 1 // Enter the statement to print the numbers in index 4 and index 9 // put a space in between the two numbers cout << endl; // Enter the statement to print the numbers 3 and 80 from the array above // put a space in between the two numbers cout << endl; // Enter the statement to change the number 1 in the array to be 12 // then write the statement to print out that number in the array cout << "\\Part 2" << endl; // Part 2 // Write a function called printAll. It takes in an array // and an integer that has the number of values in the array. // The function should print all the numbers in the array with // a space between each one. // Call the function on the line below. cout << "\\Part 3" << endl; // Part 3 // Write a function called printEven. It takes in an array and // an integer that has the number of values in the array. It prints // all the even numbers in the array with a space between each one. // This function returns the count of evens. int evens; // Call the function you just wrote and store the // answer in the variable evens declared above.

Answer and Explanation:

#include <iostream>

using namespace std;

int printEven(int array[],int n)

{

int count=0;

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

{

if(array[i]%2==0)

{

count++;

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

}

}

return count;

}

void printAll(int array[],int n)

{

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

{

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

}

}

int computeTotalOdds(int array[],int n)

{

int count=0;

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

{

if(array[i]%2!=0)

{

count++;

}

}

return count;

}

int main()

{

int array1[20] = {3, 18, 1, 25, 4, 7, 30, 9, 80, 16, 17};

int numElements = 11;

cout << "Part 1" << endl;

cout<<array1[4]<<" "<<array1[9];

cout << endl;

cout<<array1[0]<<" "<<array1[8];

cout << endl;

array1[2]=12;

cout << "\\Part 2" << endl;

printAll(array1,numElements);

cout << "\\Part 3" << endl;

int evens;

evens=printEven(array1,numElements);

// This will print the number of evens in the array.

cout << endl << evens;

cout << "\\Part 4" << endl;

int total;

total=computeTotalOdds(array1,numElements);

cout << endl << total;

return 0;
