Answer to Question #297574 in C++ for Kelly

Question

How to execute this using vector?

#include <iomanip>

#include <iostream>

using namespace std;

int main() {

const int MAXCNT = 10; // Constant

float arr[MAXCNT], x; // Array, temp. variable

float array2[MAXCNT];

int i, cnt; // Index, quantity

cout << "Enter up to 10 numbers \n"

<< "(Quit with a letter):" << endl;

for (i = 0; i < MAXCNT && cin >> x; ++i)

arr[i] = x;

cnt = i;

// copying elements of an array to another

// array2 = arr

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

array2[index] = arr[index];

cout << "The given numbers:\n" << endl;

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

cout << setw(10) << arr[i];

cout << endl;

return 0;

}

Answer 1

#include <iomanip>
#include <iostream>
#include <vector>
using namespace std;


int main() {


	const int MAXCNT = 10; // Constant
	vector<float> arr;
	vector<float> array2;
	float x;
	int i, cnt; // Index, quantity
	cout << "Enter up to 10 numbers \n"<< "(Quit with a letter):" << endl;
	for (i = 0; i < MAXCNT && cin >> x; ++i)
		arr.push_back(x);
	cnt = i;


	// copying elements of an array to another
	// array2 = arr
	for (int index = 0; index < cnt; index++)
		array2.push_back(arr[index]);
	cout << "The given numbers:\n" << endl;
	for (i = 0; i < cnt; ++i)
		cout << setw(10) << arr[i];


	cout << endl;


	system("pause");
	return 0;
