Although C++ lacks dictionaries, it does have a structure akin to them called a map. Two values−key and mapped values−are contained in each entry of a map. Each item is indexed using the key value, whereas the mapped values are the values connected to the keys. The mapped values may or may not be unique, but the keys are always unique. In this tutorial, we'll look at iterators and how they work with maps. Iterators in C++ An iterator object points to one element in a range of elements. Iterators are generally used with arrays and containers like vectors and ... Read More
Dictionaries aren’t present in C++, but it has a similar structure called map. Each entry of a map has a couple of values in it, which are key and mapped values. The key value is used for indexing each entry, whereas the mapped values are the values that are associated with the keys. Keys are unique, but the mapped values may or may not be unique. In this article, we take a look at how to initialize a map object and create it from another map object. Creating an empty map To create a map object, we need to import ... Read More
A map is a data structure in C++ and can be found in the STL class std::map. It is similar to the dictionaries that we see in Python. Each entry in a map object has a pair of values, one of which is the key value and the other is the mapped value. An entry on the map is found and uniquely identified using the key value. The key value in a map must always be unique, but the mapped value is not required to be. In this article, we focus on creating an empty map object. Creating an ... Read More
This tutorial will discuss how to write swift program to print Pascal’s triangle. A pascal’s triangle is a triangular array of the binary coefficient. It is a never ending equilateral triangle which always follows the rule of adding two numbers from the above row to get the number of below row. For example, the initial number of first row is 1 so the number of 2nd row is the sum of two numbers of the 1st row that are 0+1 and 1+0, so we get [1, 1]. Now the number of 3rd rows is the sum of the two numbers ... Read More
As a business grows, choices including stock ordering, transport, storage, and sales become more crucial. So, larger industrial storage facilities are in high demand since they facilitate the distribution of goods across a wider geographic area and thus increase the product variety available for purchase. A crucial choice in this age of fast development is whether to ship from a single hub or from a network of smaller warehouses spread across the country. There are advantages and disadvantages to both centralized and decentralized inventory systems; which one is best for a given company will depend on its structure, goals, and ... Read More
Both the Waterfall model and the V-Model are quite widely used development methodologies in the software industry. Both of these models help the development of applications in a systematic way. The basic difference between V-Model and Waterfall model is that, in the V-Model, defects are identified in the testing phase, while in the Waterfall model, defects are identified from the beginning. Read through this article to find out more about the V-Model and the Waterfall Model and how they are different from each other. What is V-Model? V-Model is the development model in which the entire model is ... Read More
Designing patterns using special characters like stars (asterisks) is one of the most common types of programs to understand looping concepts. There are plenty of other star pattern programs which are very common in nature. The star pyramid is fairly simple but much more effective to understand looping statements and their conditions. In this article, we will see how to display a square pattern using stars in C++. Initially the complete square and then the hollow square. Displaying Complete Square Pattern * * * * * * * * * * * * * * * * * * * ... Read More
Understanding looping ideas is made simpler by printing a star design. Asterisks are used in a variety of star patterns to form complete or hollow triangles or diamond forms. In this post, we will show how to create a center-aligned descending triangle in C++. The following table will contain the logic we create to print stars. The following table can help us understand. Syntax * * * * * * * * * * * * * * * * * * * * * * * * * ... Read More
When learning programming, displaying a star pattern makes looping concepts easier to get. The star patterns are various designs that use asterisks to create hard or hollow triangles or diamond forms. This article will demonstrate a C++ implementation for an upward triangle that is center-aligned. The following table will contain the logic we create to print stars. The following table can help us understand. * * * * * * * * * * * * * * * ... Read More
Every business transaction has its own unique selling environment. Therefore, consumer markets and business markets are different in important ways that are often overlooked. Businesses that cater to consumers sell their products directly to consumers, whereas businesses that cater to other businesses acquire raw materials and intermediate products to employ in the production of their own goods and services. This essay will break down the several key differences between retail and wholesale markets. What are Business Markets? Business markets consist of companies and other organizations that buy raw materials and intermediates for use in production. Products and services that are ... Read More
