Solution
The correct answer is "Use a for loop with an if statement and break when found".
Here is a step by step explanation:
-
Initialize a for loop to iterate over the array. The loop should start at the first index (usually 0) and end at the last index of the array.
-
Inside the loop, use an if statement to check if the current element is equal to the specific element you are looking for.
-
If the if statement is true (meaning the current element is the one you are looking for), then use the break statement to exit the loop. This will stop the loop from continuing to iterate over the rest of the array once the specific element is found.
-
If the if statement is false (meaning the current element is not what you are looking for), then the loop will continue to the next iteration.
-
If the loop completes without finding the specific element, then the element does not exist in the array.
