Day 5: Loops | HackerRank Solution

Hello coders, today we are going to solve Day 5: Loops HackerRank Solution in C++, Java and Python.

Objective

In this challenge, we will use loops to do some math.

Task

Given an integer, n, print its first 10 multiples. Each multiple n x i (where 1 <= i <= 10) should be printed on a new line in the form: n x i = result.

Example

n = 3

The printout should look like this:

3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30

3 x 1 = 3

3 x 2 = 6

3 x 3 = 9

3 x 4 = 12

3 x 5 = 15

3 x 6 = 18

3 x 7 = 21

3 x 8 = 24

3 x 9 = 27

3 x 10 = 30

Input Format

A single integer, n.

Constraints

2 <= n <= 20

Output Format

Print 10 lines of output; each line i (where 1 <= i <= 10) contains the result of n x i in the form:
n x i = result.

Sample Input

2

Sample Output

2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8
2 x 5 = 10
2 x 6 = 12
2 x 7 = 14
2 x 8 = 16
2 x 9 = 18
2 x 10 = 20

2 x 1 = 2

2 x 2 = 4

2 x 3 = 6

2 x 4 = 8

2 x 5 = 10

2 x 6 = 12

2 x 7 = 14

2 x 8 = 16

2 x 9 = 18

2 x 10 = 20

C++

#include &lt;bits/stdc++.h>

using namespace std;

int main()

{

int n;

cin >> n;

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

if(2&lt;=n&lt;=20)

{

for (int i = 1; i &lt;= 10; i++)

{

cout &lt;&lt;n&lt;&lt;" "&lt;&lt;"x"&lt;&lt;" "&lt;&lt;i&lt;&lt;" "&lt;&lt;"="&lt;&lt;" "&lt;&lt;(n*i)&lt;&lt; endl;

}

}

return 0;

}

#include <bits/stdc++.h>

using namespace std;

int main()

{

int n;

cin >> n;

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

if(2<=n<=20)

{

for (int i = 1; i <= 10; i++)

{

cout <<n<<" "<<"x"<<" "<<i<<" "<<"="<<" "<<(n*i)<< endl;

}

return 0;
