Find Even Numbers From a List Using While Loop

In this lab, you will learn how to find even numbers from a list using a while loop.

Create a file called even_numbers.c and open it in WebIDE.

Copy and paste the following code into the even_numbers.c file:

#include <stdio.h>

int main() {
  int numbers[] = { 21, 78, 62, 90, 55, 10, 85, 45, 11, 2 };
  int size = sizeof(numbers) / sizeof(numbers[0]);
  int i = 0;

  printf("The even numbers from the list are:\n\n");

  while (i < size) {
    if (numbers[i] % 2 == 0) {
      printf("EVEN: %d\n", numbers[i]);
    }
    i++;
  }

  return 0;
}

Save the file.
Open a terminal and navigate to the directory where the even_numbers.c file is saved.
Compile the code using the command gcc even_numbers.c -o even_numbers.
Run the program by entering ./even_numbers in the terminal.

Summary

After completing this lab, you will be able to use a while loop to find even numbers from a list of integers. The program will output the even numbers from the list on the terminal.
