What you’ll learn

How to print a times table with a simple for loop.
A clean row format: base x i = product.
Two examples: fixed base and user-selected base, plus live preview and tryit pages.

Overview

For a base number n, print n x 1 through n x 10. The loop counter changes, the formula stays the same.

Live preview

Default base is 5. Change it and print 1 to 10.

Algorithm

Goal: print base x i for i = 1..10.

📜 Pseudocode

Pseudocode

procedure printTable(base, last):
    for i from 1 to last:
        print base, i, base * i

Table for 5 (fixed base)

JavaScript

function printMultiplicationTable(base, last) {
  console.log("Multiplication table for " + base + ":");

  for (let i = 1; i <= last; i++) {
    console.log(base + " x " + i + " = " + base * i);
  }
}

const base = 5;
const last = 10;
printMultiplicationTable(base, last);

Table for a number you choose

JavaScript

function printMultiplicationTable(base, last) {
  console.log("Multiplication table for " + base + ":");

  for (let i = 1; i <= last; i++) {
    console.log(base + " x " + i + " = " + base * i);
  }
}

const raw = prompt("Enter a positive integer:");
const n = Number(raw);

if (!Number.isInteger(n) || n <= 0) {
  console.log("Please enter a positive integer.");
} else {
  printMultiplicationTable(n, 10);
}

❓ FAQ

What is a multiplication table?

It lists products for one base number, such as n x 1, n x 2, and so on, usually up to 10.

Why use a loop for this?

Each row follows the same formula base * i. A loop changes only i and prints all rows cleanly.

Why does the table usually stop at 10?

That is a common school convention. You can print to 12, 20, or any positive limit.

Can I print tables for negative numbers?

Yes, multiplication still works. Many beginner programs restrict input to positive values for familiar classroom output.

Should I use for or while?

Either works. for is convenient when you know the exact range, like 1 through 10.

What is the complexity?

Printing k rows is O(k) time and O(1) extra space besides the output text.

Edge cases

Invalid input

Not an integer

Show a clear message instead of printing bad rows.

Range

Large values

Products get large quickly; keep examples in a practical range.

⏱️ Time and space complexity

Task	Time	Extra space
Print 10 rows	`O(10)` (constant)	`O(1)`

Summary

Core loop: print base x i for each row.
Pattern: same expression each line, only i changes.

Did you know?

A multiplication table for a number n is just repeated products: n x 1, n x 2, and so on. A loop is perfect because only the counter changes each row.
