C++ Basics: Moving Resources

Introduction — Why Moving Resources

When writing a program you will encounter a case where you need to move (large) resources around from one object to another.

In C++ we have move semantics which is a way to move resources to avoid making copies in the memory which not only will make our program slower but also use more space than necessary.

We are not discussing the Move Semantics here, because there are a lot of resources you can find on the internet explaining rvalues and Move Semantics.

What is not so obvious is that when we can rely on the compiler to help us move our resources around, and when we have to write our own move constructor and move assignment operator.

How to Run C/C++ in Sublime Text?

C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.

In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.

During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. Vim, Sublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.

I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using freopen file related functions in C/C++.

Dicey Issues in C/C++

If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends. The following displays some of the issues:

1. Using multiple variables in the print function
2. Comparing Signed integer with unsigned integer
3. Putting a semicolon at the end of the loop statement
4. C preprocessor doesn’t need a semicolon
5. Size of the string matters
6. Macros and equations aren’t good friends
7. Never compare Floating data type with double data type
8. Arrays have a boundary
9. Character constants are different from string literals
10. Difference between single(=) and double(==) equal signs.

The below code generates no error since a print function can take any number of inputs but creates a mismatch with the variables. The print function is used to display characters, strings, integers, float, octal, and hexadecimal values onto the output screen. The format specifier is used to display the value of a variable.

1. %d indicates Integer Format Specifier
2. %f indicates Float Format Specifier
3. %c indicates Character Format Specifier
4. %s indicates String Format Specifier
5. %u indicates Unsigned Integer Format Specifier
6. %ld indicates Long Int Format Specifier

A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0 to 4294967295]. The signed integer is represented in twos-complement notation. In the below code the signed integer will be converted to the maximum unsigned integer then compared with the unsigned integer.

Some basic models of Machine Learning using C#

The Basics of Machine Learning Modeling

It can be difficult to see how machine learning (ML) affects the daily lives of ordinary people. In fact, ML is everywhere! In the process of searching for a restaurant for dinner, you almost certainly used ML. In the search for a dress to wear for a dinner party, you would have used ML. On your way to your dinner appointment, you probably used ML as well if you used one of the ride-sharing apps. ML has become so widely used that it has become an essential part of our lives, although it is usually unnoticeable. With ever-growing data and its accessibility, the applications and needs for ML are rapidly rising across various industries. However, the pace of the growth in trained data scientists has yet to meet the pace of growth ML needs in businesses, despite abundant resources and software libraries that make building ML models easier, due to the fact that it takes time and experience for a data scientist and ML engineer to master such skill sets.

In this article, we will cover the following topics:

• Key ML tasks and applications
• Steps in building ML models
