# JavaScript: Display a message when a number is between a range

## JavaScript Basic: Exercise-8 with Solution

Write a JavaScript program where the program takes a random integer between 1 and 10, and the user is then prompted to input a guess number. The program displays a message "Good Work" if the input matches the guess number otherwise "Not matched".

Sample Solution:

JavaScript Code:

``````// Generate a random integer between 1 and 10 (inclusive)
var num = Math.ceil(Math.random() * 10);

// Log the generated random number to the console
console.log(num);

// Prompt the user to guess a number between 1 and 10 (inclusive)
var gnum = prompt('Guess the number between 1 and 10 inclusive');

// Check if the guessed number matches the generated random number
if (gnum == num)
// Log a message if the guessed number matches the random number
console.log('Matched');
else
// Log a message if the guessed number does not match, and also provide the correct number
console.log('Not matched, the number was ' + gnum);
```
```

Output:

```Matched
```

Explanation:

The Math.ceil() function is used to get the smallest integer greater than or equal to a given number.

The Math.random() function is used to get a floating-point, pseudo-random number in the range [0, 1] that is, from 0 (inclusive) up to but not including 1 (exclusive), which you can then scale to your desired range.

Flowchart:

ES6 Version:

`````` // Generate a random integer between 1 and 10 (inclusive)
const num = Math.ceil(Math.random() * 10);

// Log the generated random number to the console
console.log(num);

// Prompt the user to guess a number between 1 and 10 (inclusive)
const gnum = prompt('Guess the number between 1 and 10 inclusive');

// Check if the guessed number matches the generated random number
if (gnum == num) {
// Log a message if the guessed number matches the random number
console.log('Matched');
} else {
// Log a message if the guessed number does not match, and also provide the correct number
console.log('Not matched, the number was ' + gnum);
}
``````
