A linear sequential data structure called an array is used to store homogeneous data in a series of memory regions. An array needs to have certain features to insert, delete, traverse, and update elements effectively, just like other data structures do. Our arrays in C++ are static. In addition, C++ offers a few dynamic array structures. There may be a maximum of Z elements that can be stored inside a static array. And there are currently n elements in it. In this article, we will see how to push the elements of one array inside another array in C++. Understanding ... Read More

An array is a linear sequential data structure to hold homogeneous data in consecutive memory locations. Like other data structures, an array also must-have features to insert, delete, traverse and update elements in some efficient way. In C++, our arrays are static. There are a few dynamic array structures also available in C++. For a static array, there may be a Z number of elements that can be stored inside that array. And till now we have n elements into it. In this article, we will see how to insert an element at the end of an array (which is ... Read More

This tutorial will discuss how to write swift program to print spiral pattern. Numeric pattern is a sequence of numbers which is used to develop different patterns or shapes like pyramid, rectangle, cross, etc. These numeric patterns are generally used to understand or practice the program flow controls, also they are good for logical thinking. To create a spiral pattern of numbers, we can use any of the following methods − Using nested for loop Using stride Function Below is a demonstration of the same − Input Suppose our given input is − Num = 6 Output ...

Private members of a class are only accessed by the members of the class. This is done to preserve the object-oriented paradigm encapsulation, which ensures data and its related functions are kept in one unit and only accessible only from a member of that class. C++ has three different access specifiers to specify the visibility of the members of a class. The three access specifiers are − Public − If a member of a class has the visibility public, then the members can be accessed from any other class. Private − Class members having private visibility can be accessed from ... Read More

In this article, we learn to create custom-made, user−defined exceptions in C++. Exceptions are a core concept of C++. They occur when an unwanted or impossible operation occurs during execution. Handling these unwanted or impossible operations is known as exception handling in C++. What is Exception Handling? Exception handling is mainly done using three specific keywords: ' try’, ‘catch’, and ‘throw’. The ‘try’ keyword is used to execute code that may encounter an exception, the ‘catch’ keyword is used to handle such exceptions, and the ‘throws’ keyword is used to create an exception. Exception Types Exceptions in C++ can be divided ... Read More

This tutorial will discuss how to write swift program to convert array to a string. String is an ordered collection of characters. For example: “TutorialsPoint”, “Pinky”, etc. To create a string type variable we use String keyword. var str : String Array is a collection of similar data types. Like any array of integer can contain only integer values, it does not accept string values. var arr = [Int] To convert an array to a string we can use any of the following method. Below is a demonstration of the same − Input Suppose our given input is ... Read More

This tutorial will discuss how to write swift program to convert string type variable to boolean. Swift support various datatypes and string and bool are one of them. String is an ordered collection of characters. For example: “TutorialsPoint”, “Pinky”, etc. To create a string type variable we use String keyword. Whereas Boolean represent bool values. Bool has only two values either true or false. And to create boolean type variable we use Bool keyword. Swift does not provide any dedicated constructor (like String(), Int())to convert String into Bool. So we can convert boolean to string using any of the following ... Read More

This tutorial will discuss how to write swift program to convert boolean type variable to string. Swift support various datatypes and string and bool are one of them. String is an ordered collection of characters. For example: “TutorialsPoint”, “Pinky”, etc. To create a string type variable we use String keyword. Whereas Boolean represent bool values. Bool has only two values either true or false. And to create boolean type variable we use Bool keyword. To convert bool type variable into string we uses String() function. This function convert any data type into string. Syntax Following is the syntax − String(variableName) ... Read More

The ‘this’ keyword in C++ is very important and it is used in multiple use cases. The ‘this’ keyword or the ‘this’ pointer is used as an implicit object parameter when an object’s member function is called and refers to the invoking object. We take a look at the different use cases of the ‘this’ keyword. Syntax The ‘this’ keyword is used in the following way this->variable_name; Use Case 1: Resolving Variable Shadowing Variable shadowing is a very common use case for the ‘this’ pointer. Variable shadowing occurs when a class member variable and another parameter ... Read More
