As we know, numbers can be classified into two types – even numbers and odd numbers. In this article, we will explore what these numbers are and how they can be identified. We will also provide code examples to find even and odd numbers from 1 to 100 using different programming languages.

What are Even and Odd numbers?

An even number is any integer that can be divided exactly by 2. This means that when an even number is divided by 2, the remainder is always 0. Examples of even numbers include 2, 4, 6, 8, 10, and so on.

On the other hand, an odd number cannot be divided exactly by 2. This means that when an odd number is divided by 2, the remainder is always 1. Examples of odd numbers include 1, 3, 5, 7, 9, and so on.

How to identify Even and Odd numbers?

To identify whether a number is even or odd, we can use the modulus operator. The modulus operator (%) returns the remainder of a division operation. Hence, if we divide a number by 2 and get a remainder of 0, then the number is even. If we divide a number by 2 and get a remainder of 1, then the number is odd.

For example:

If we divide 4 by 2, we get a remainder of 0. Hence, 4 is an even number.

If we divide 5 by 2, we get a remainder of 1. Hence, 5 is an odd number.

Getting Even and Odd numbers from 1 to 100:

Now, let’s see how we can get even and odd numbers from 1 to 100 using different programming languages:

Python:

In Python, we can use a for loop to iterate from 1 to 100 and use the modulus operator to check whether a number is even or odd. We can print all even and odd numbers using the print() function.

Code:

```
for i in range(1, 101):
if i % 2 == 0:
print(i, "is even")
else:
print(i, "is odd")
```

Output:

```
1 is odd
2 is even
3 is odd
4 is even
5 is odd
6 is even
7 is odd
8 is even
9 is odd
10 is even
11 is odd
12 is even
...
```

Java:

In Java, we can use a for loop to iterate from 1 to 100 and use the modulus operator to check whether a number is even or odd. We can print all even and odd numbers using the System.out.println() method.

Code:

```
for (int i = 1; i <= 100; i++) {
if (i % 2 == 0) {
System.out.println(i + " is even");
} else {
System.out.println(i + " is odd");
}
}
```

Output:

```
1 is odd
2 is even
3 is odd
4 is even
5 is odd
6 is even
7 is odd
8 is even
9 is odd
10 is even
11 is odd
12 is even
...
```

C++:

In C++, we can use a for loop to iterate from 1 to 100 and use the modulus operator to check whether a number is even or odd. We can print all even and odd numbers using the cout statement.

Code:

```
for (int i = 1; i <= 100; i++) {
if (i % 2 == 0) {
cout << i << " is even" << endl;
} else {
cout << i << " is odd" << endl;
}
}
```

Output:

```
1 is odd
2 is even
3 is odd
4 is even
5 is odd
6 is even
7 is odd
8 is even
9 is odd
10 is even
11 is odd
12 is even
...
```

Conclusion:

In this article, we learned about even and odd numbers, how they can be identified, and how to get even and odd numbers from 1 to 100 using different programming languages. It is important to understand the concept of even and odd numbers as they play an important role in mathematics and programming.

## Popular questions

Absolutely! Here are five questions with answers related to the topic of even and odd numbers 1 to 100 with code examples:

Q: What is an even number?

A: An even number is any integer that can be divided exactly by 2. This means that when an even number is divided by 2, the remainder is always 0. Examples of even numbers include 2, 4, 6, 8, 10, and so on.

Q: What is an odd number?

A: An odd number cannot be divided exactly by 2. This means that when an odd number is divided by 2, the remainder is always 1. Examples of odd numbers include 1, 3, 5, 7, 9, and so on.

Q: How can we identify whether a number is even or odd?

A: We can use the modulus operator (%) to identify whether a number is even or odd. If we divide a number by 2 and get a remainder of 0, then the number is even. If we divide a number by 2 and get a remainder of 1, then the number is odd.

Q: What is the output of the code example for finding even and odd numbers from 1 to 100 in Python?

A: The output of the Python code example for finding even and odd numbers from 1 to 100 is a list of numbers from 1 to 100 with an indication of whether each number is even or odd. For example, the output would look like this:

1 is odd

2 is even

3 is odd

4 is even

5 is odd

6 is even

…and so on, up to 100.

Q: Can the code example for finding even and odd numbers from 1 to 100 in Java be used to find even and odd numbers beyond 100?

A: Yes, the code example for finding even and odd numbers from 1 to 100 in Java can be modified to find even and odd numbers beyond 100. We can change the for loop to iterate from the starting number to the ending number, and use the same logic to check whether each number is even or odd.
