Kotlin Program to Generate Multiplication Table

In this article, we will understand how to print a multiplication table. Multiplication table is created by iterating the required input 10 times using a for loop and multiplying the input value with numbers from 1 to 10 in each iteration.

Below is a demonstration of the same ?

Suppose our input is ?

Input : 16

The desired output would be ?

The multiplication table of 16 is :
16 * 1 = 16
16 * 2 = 32
16 * 3 = 48
16 * 4 = 64
16 * 5 = 80
16 * 6 = 96
16 * 7 = 112
16 * 8 = 128
16 * 9 = 144
16 * 10 = 160

Algorithm

• Step 1 ? START

• Step 2 ? Declare two integer values namely myInput and i.

• Step 3 ? Define the value

• Step 4 ? Iterate from 1 to 10 using a for-loop, and in each iteration, multiply the numbers 1 to 10 with the input.

• Step 5 ? Display the resulting value in after each iteration.

• Step 6 ? Stop

Example 1

In this example, we will generate Multiplication Table using for loop. First, declare and initialize the input for which you want the multiplication table ?

val myInput = 16

Now, use a for loop from 1 to 10 since we want to display a table ?

<div class="code-mirror  language-kotlin" contenteditable="plaintext-only" spellcheck="false" style="outline: none; overflow-wrap: break-word; overflow-y: auto; white-space: pre-wrap;"><span class="token keyword">for</span> <span class="token punctuation">(</span>i <span class="token keyword">in</span> <span class="token number">1</span><span class="token operator">..</span><span class="token number">10</span><span class="token punctuation">)</span> <span class="token punctuation">{</span>
   <span class="token keyword">val</span> product <span class="token operator">=</span> myInput <span class="token operator">*</span> i
   <span class="token function">println</span><span class="token punctuation">(</span><span class="token string">"<span class="token interpolation variable">$myInput</span> * <span class="token interpolation variable">$i</span> = <span class="token interpolation variable">$product</span>"</span><span class="token punctuation">)</span>
<span class="token punctuation">}</span>
</div>

Let us now see the complete example to generate Multiplication Table using for loop ?

<div class="execute"></div><div class="code-mirror  language-kotlin" contenteditable="plaintext-only" spellcheck="false" style="outline: none; overflow-wrap: break-word; overflow-y: auto; white-space: pre-wrap;"><span class="token keyword">fun</span> <span class="token function">main</span><span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token punctuation">{</span>
   <span class="token keyword">val</span> myInput <span class="token operator">=</span> <span class="token number">16</span>
   <span class="token function">println</span><span class="token punctuation">(</span><span class="token string">"The input is defined as <span class="token interpolation variable">$myInput</span>"</span><span class="token punctuation">)</span>
   <span class="token function">println</span><span class="token punctuation">(</span><span class="token string">"\nThe multiplication table of <span class="token interpolation variable">$myInput</span>"</span><span class="token punctuation">)</span>
   
   <span class="token keyword">for</span> <span class="token punctuation">(</span>i <span class="token keyword">in</span> <span class="token number">1</span><span class="token operator">..</span><span class="token number">10</span><span class="token punctuation">)</span> <span class="token punctuation">{</span>
      <span class="token keyword">val</span> product <span class="token operator">=</span> myInput <span class="token operator">*</span> i
      <span class="token function">println</span><span class="token punctuation">(</span><span class="token string">"<span class="token interpolation variable">$myInput</span> * <span class="token interpolation variable">$i</span> = <span class="token interpolation variable">$product</span>"</span><span class="token punctuation">)</span>
   <span class="token punctuation">}</span>
<span class="token punctuation">}</span>
</div><div class="output-wrapper"><div class="console-close"></div><div class="code-output"></div></div>

Output

The input is defined as 16
The multiplication table of 16
16 * 1 = 16
16 * 2 = 32
16 * 3 = 48
16 * 4 = 64
16 * 5 = 80
16 * 6 = 96
16 * 7 = 112
16 * 8 = 128
16 * 9 = 144
16 * 10 = 160

Example 2

In this example, we will generate Multiplication Table ?

<div class="execute"></div><div class="code-mirror  language-kotlin" contenteditable="plaintext-only" spellcheck="false" style="outline: none; overflow-wrap: break-word; overflow-y: auto; white-space: pre-wrap;"><span class="token keyword">fun</span> <span class="token function">main</span><span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token punctuation">{</span>
   <span class="token keyword">val</span> myInput <span class="token operator">=</span> <span class="token number">16</span>
   <span class="token function">println</span><span class="token punctuation">(</span><span class="token string">"The input is defined as <span class="token interpolation variable">$myInput</span>"</span><span class="token punctuation">)</span>
   <span class="token function">multiplicationTable</span><span class="token punctuation">(</span>myInput<span class="token punctuation">)</span>
<span class="token punctuation">}</span>

<span class="token keyword">fun</span> <span class="token function">multiplicationTable</span><span class="token punctuation">(</span>myInput<span class="token operator">:</span> Int<span class="token punctuation">)</span> <span class="token punctuation">{</span>
