Question

Create a new file (in Dev C++)

Modify program above to use a vector instead of an array.

• Header comments must be present
• Prototypes must be present if functions are used
• Hello and goodbye messages must be shown
• Vector(s) must be used for implementation
• Use comments and good style practices

======================================================================================================
#include <iostream>

using namespace std;

int main() {

cout<<"Welcome! This program will find the minimum and maximum numbers in an array."<<endl;

cout<<"You will be asked to enter a number ten times. Then, the program will display"<<endl;

cout<<"the numbers back to you and indicate which is the smallest and which is the largest."<<endl<<endl;

int arr[10],min=1000,max=-1;

for(int i=0;i<10;i++){

cout<<"Please enter a number: ";

cin>>arr[i];

if(min>arr[i])

min=arr[i];

if(max<arr[i])

max=arr[i];

}

cout<<"\nValues: ";

for(int i=0;i<10;i++)

cout<<arr[i]<<" ";

cout<<"\nMinimum: "<<min<<endl;

cout<<"Maximum: "<<max<<endl;

cout<<"\nExiting program. Goodbye!";

}

#include <iostream>
#include <vector>

using namespace std;

void hello();

void goodbye();

void printVector(vector<int> v);

int minVector(vector<int> v);

int maxVector(vector<int> v);

int main() {
    int num;
    vector<int> v;
    hello();
    for (int i = 0; i < 10; i++) {
        cout << "Please enter a number: ";
        cin >> num;
        v.push_back(num);
    }
    printVector(v);
    cout << "\nMinimum: " << minVector(v) << endl;
    cout << "Maximum: " << maxVector(v) << endl;
    goodbye();

    cout << "You will be asked to enter a number ten times. Then, the program will display" << endl;
    cout << "the numbers back to you and indicate which is the smallest and which is the largest." << endl << endl;
