How to Print All Even and Odd Numbers Between 100 and 1 Using Different Programming Languages

The task of printing all even and odd numbers between 100 and 1 is an interesting exercise that can be accomplished in various programming languages. In this article, we will examine how to achieve this in C, Python, and C .

Code Implementation in C

In C, the process involves a few straightforward steps. We start by including the necessary header files and defining the main function. Below is an example of how to do it:

#include stdio.h int main() { printf("Even numbers between 100 and 1:"); for (int i 100; i ! 1; i - 2) { printf(" %d", i);
} printf(" Odd numbers between 100 and 1:"); for (int i 99; i ! 1; i - 2) { printf(" %d", i); } return 0; }

This code prints all even and odd numbers between 100 and 1. Note that the loops start from 100 and 99, respectively, and decrement by 2 until reaching 1.

Code Implementation in Python

Python offers a more concise and readable solution. In Python, we can use list comprehensions and simple for-loops:

even [i for i in range(101) if i % 2 0] odd [i for i in range(101) if i % 2 ! 0] print(f'Even numbers between 1 to 100: {even}') print(f'Odd numbers between 1 to 100: {odd}')

This code uses list comprehensions to generate even and odd numbers and then prints them out. The range function is used to iterate through the numbers from 0 to 100, and the modulo operator `%` is used to determine if a number is even or odd.

Code Implementation in C

In C , the process is very similar to C. We need to define the main function and use for-loops to iterate through the numbers:

#include iostream using namespace std; int main() { cout "Even numbers between 100 and 1: "; for (int a 100; a > 1; a - 2) { cout a " "; } cout endl; cout "Odd numbers between 100 and 1: "; for (int a 99; a > 1; a - 2) { cout a " "; } cout endl; return 0; }

This code uses a similar approach with loops, though in C we use the `cout` object from the `iostream` library to print the output.

Conclusion

Printing even and odd numbers between 100 and 1 is a simple exercise that demonstrates the use of loops and conditional statements in programming. The above examples show how to achieve this in C, C , and Python. Each programming language offers different syntactical advantages, and understanding these can help improve your programming skills.

Frequently Asked Questions

Q: How do you check if a number is even or odd in Python?
A: In Python, you can use the modulo operator `%` to check if a number is even or odd. A number is even if the result of n % 2 is 0, and odd if it is 1.

Q: Can you sort even and odd numbers in descending order?
A: Yes, you can sort the lists of even and odd numbers in descending order by using the `sorted()` function with the `reverseTrue` parameter. For example:

(reverseTrue) (reverseTrue)

This will sort the lists in descending order.
