C Pointer Program to get the last name from a full name

-
Image
C Language Flag / Logo Another C programming here, this article will simply explain how to do char array operation in C language to get the last word from a whole sentence, or in this case we just rename our function to be more specific to get a person last name from its full name. This is a very simple C function to get a user last name from a user full name. This function will do some pointer operation, so if you are trying to learn about pointer in C, this may help you little bit on understanding about a pointer in C: char * get_last_name(char * full_name) { char *last_name = full_name; int last_space=0; for(int i=0; i 0) last_space+=1; last_name += last_space; return last_name; } This function will loop through all the characters bit by bit and will try to find any spaces located on that character. If a space is found, then store the last space pointer location and return that pointer as its function return. - We define our function called get_last_name to ...

Recursive Function In C : Fibonacci, Factorial and Power of Numbers

Image
C Language Flag / Logo These are some example programs in the C language using recursive function to calculate Fibonacci, Factorial and Power of numbers. You can use a loop, but for a purpose of giving you an example on how to use recursive so we are going to use recursive instead. Fibonacci This is to calculate the sum of fibonacci numbers that are less than the specified number user input. int fibonacci(int number) { if(number == 0){ return 0; } else if(number == 1) { return 1; } else { return (fibonacci(number - 1) + fibonacci(number - 2)); } } - Our function accept integer, then we compare them using if statement - If the parameter number equal to 0, then the return of function is 0 - Also If the parameter number equal to 1, then the return of function is 1 - But if the number is not 1 or 0, this function will call itself with a new parameter for the first call is the parameter -1 and the second parameter -2, then add both results. - This ...

Everthing on the clouds soon - Google Drive, Onedrive and Windows File Explorer

File Explorer, Google Drive, One Drive As a forever Windows user, I have been using File explorer since the very first time I knew about this OS. It is the default program for browsing files on our computer, so we were familiarised with its feature, and that it’s very convenient to use, work smoothly, and make it very efficient for our daily use. Windows file explorer is a very simple program basically just showing a bunch of files, with its properties like file name, size, file format, date created, date updated, type of the files and many more handy features. Just like most file explorers in any operating system. File explorer actually has many more functionalities behind it, but for me i have never used most of them because file explorer is file explorer, it is just for working with files. Some features in file explorer  for example i have never used is the search box that is on the right top of the windows. I have almost never used it for example because it’s not always showing...

MySQL and MariaDB password As already mentioned in the title of this blog, this error message sometimes occurred when we are trying to update our root password database, either MySQL or MariaDB, The error says: ERROR 1348 (HY000): Column 'Password' is not updatable This is because if we use this SQL command to update our database root password, and it turn out to be Restricted by MySQL to use update on mysql database. UPDATE mysql.user SET Password=PASSWORD('1234') WHERE User='root'; The solutions for MySQL Error1348 So you can not update a user password using Update commands, to update the password, use ALTER commands instead. like the following. ALTER USER 'root'@'localhost' IDENTIFIED BY '1234'; And then you need to do the flush privileges to commit previous queries (that alter command above) into the system, simply do like this. flush privileges; So now you have your root with password 1234. Although it is recommended to...

How To Create Spring Boot Project Using Netbeans

Spring Boot is a handy tool that simplifies the development of Spring Framework applications by reducing the need for cumbersome configuration. In this tutorial, I'll guide you through creating a Spring Boot application using the Netbeans IDE. While you can certainly create a Spring Boot application in Netbeans manually, it's much easier with a plugin designed for Spring development. Here's a step-by-step guide to get you started: 1. Install the Spring Boot Plugin: Open Netbeans and navigate to the Tools menu. Click on "Plugins." Once the Plugins window opens, select the "Available Plugins" tab. Look for the "Nb SpringBoot" plugin, then install and activate it. 2. Create a New Spring Boot Project: After restarting Netbeans IDE, you can create a new project with Spring Boot. Go to File > New Project. Under Categories, select Maven, then choose "Spring Boot Basic." 3. Add Dependencies: With your new project created, open the po...

Spring Kafka - How to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Today, I want to share how to use Kafka. It's quite interesting once you get the hang of it, and I hope my explanation will make it a bit easier for you. So, Kafka is primarily known as an asynchronous messaging queuing system. This means it allows different parts of your application to communicate with each other without waiting for immediate responses. However, there are times when you might need a more immediate reply from another service in your project. Luckily, Kafka can handle this too. Here’s how it works: The client side sends a message to the server side via Kafka. This message includes a special identifier in the Kafka header request, known as KafkaHeaders.CORRELATION_ID, along with a topic where the server should respond. The server, after processing the request, sends a message back to the same topic with the same correlation ID. This way, the client knows that the message is a response to its initial request and can act accordingl...
