C++ array and for-loop

Introduction

Array is a collection of similar data types. It is a fixed-size container that holds a number of elements.

Example:
int arr[5];

Declares an array of 5 integers.
In order to access the elements of an array, we use an index. The index starts from 0.
First element of the array is arr[0], second element is arr[1], and so on.

In order to access all the elements of an array, we usually use a for-loop.
For-loop is a control flow statement that allows code to be executed repeatedly based on a given condition.

Example:

for(int i=0; i<5; i++) {
	cout << arr[i] << " ";
}

Code - Enter 5 numbers

#include <iostream>
using namespace std;

int main() {
	int arr[5];
	cout << "Enter 5 numbers: ";
	for(int i=0; i<5; i++) {
		cin >> arr[i];
	}
}

Code - Enter 5 numbers and display them

#include <iostream>
using namespace std;

int main() {
	int arr[5];
	cout << "Enter 5 numbers: ";
	for(int i=0; i<5; i++) {
		cin >> arr[i];
	}
	cout << "You entered: ";
	for(int i=0; i<5; i++) {
		cout << arr[i] << " ";
	}
}

Task

Show the first ten multiples of entered number.
Hints: multiple the number with counter (i) in the for-loop.
