Vectors are similar to the dynamic arrays but vectors can resize. They are sequence containers that can change their size according to the insertion or deletion of elements. Containers are the objects which holds the data of same type. Vectors may allocate some extra storage for the future growth of elements in the vector. Its elements are stored in the contiguous memory. The data is entered at the end of vector. In this article, we will show you how to print the contents of a vector in C++. Example Scenario: std::vector vec = {10, 20, 30, 40, 50}; You ... Read More
In C++, one common task is to find the largest number in an array. An array is just a collection of values, and sometimes we need to find the highest value in that collection. For example, consider the array: int arr[] = {11, 13, 21, 45, 8}; In this case, the largest element is 45. Similarly, for the array: int arr[] = {1, 9, 2, 5, 7}; The largest number is 9. In this article, we will show you how to find the largest number in an array using different methods in C++, including some built-in features ... Read More
What is File Carving? File Carving is a popular way to get files back from computer memory by using details about their content and structure instead of the file system. This method is very important for digital forensics investigations because it lets you get back files by looking at their text and structure. Getting structured information from raw data based on format-specific properties found in the structured data is what this broad term refers to. The Problem of Destroyed or Deleted Data There are several reasons why files might get deleted. Any of these things can happen by mistake, as ... Read More
In this article, we will learn about Java API documentation generators.

If strict SQL mode is disabled and we insert an invalid value (which is not in the list of permitted enumeration values) into ENUM, MySQL will insert an empty string instead of throwing an error. If strict SQL mode is enabled, MySQL throws an error when inserting invalid value. Invalid values without strict SQL mode Strict SQL mode is disabled by default. When it is disabled, if we enter an invalid value that is not in the ENUM list, it returns an empty string. Let us understand this by using the example below. Example In the below example we have ...

Events perform tasks based on a predefined schedule, such as cleaning data once a day or doing backups, while Triggers are activated automatically when some actions are executed, like an INSERT, UPDATE, or DELETE. Despite their differences, events, and triggers can be used together to manage scheduled and reactive automation tasks. This article will show you the relationship and illustrate how they can enhance database management when combined effectively. Relationship Between MySQL Events and Triggers By making use of the strengths of events and triggers, we can design a ideal workflow that can efficiently handle real-time responses and scheduled ...
