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

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

C++ does not have dictionaries by the same name as it is in python, but it has the same data structure having similar capabilities. C++ has support for maps, which is available in the STL class std::map. A map object contains a pair of values in each entry, one is a key value and the other one is the mapped value. The key value is used to search and uniquely identify an entry in the map. Whereas the mapped value is not always unique, the key value has to be always unique in a map. Let’s take a look at ...

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

When learning programming, displaying a star pattern makes looping concepts easier to comprehend. The star patterns are various designs that use asterisks to create hard or hollow triangles or diamond forms. This article will demonstrate a C++ right-aligned mirrored upper triangle pattern. The following table will contain the logic we create to print stars. The following table can help us understand. * * * * * * * * * * * * * * * * * * * ... Read More

Asterisks "*" are used in star patterns to represent various shapes, such as right-angled triangles or other triangular and diamond shapes. Star patterns are the names for these forms. This tutorial will demonstrate how to use C++ to display the upper left triangle star pattern. Here, we accept as an input the number of lines in the star design. For that many lines, the pattern will be printed. The following table will contain the logic we create to print stars. The following table can help us understand. * * * * * * * * * * * * * ...

The purpose of an array is to provide access to the same type of data across several memory locations via base addresses and indexes. In a wide variety of applications, arrays are used to store data for a wide range of reasons. The array must efficiently handle adding, removing, and updating elements, just like other data structures. Both static and dynamic arrays include a number of library functions in C++ that handle various array-related operations. But in this article, we will see how to delete an element from an array without using any library functions in C++. Understanding the concept ... Read More

Star patterns are interesting problems to display different shapes like right-angled triangles or other triangular and diamond shapes using asterisks ‘*’. These shapes are called star patterns. In this article, we will see how to display the left triangle start pattern in C++. Here we take the number of lines for the star pattern as input. It will print the pattern for that number of lines. We will develop the logic to print stars in the following table. Let us follow the table for a better understanding − * * * * * * * * * * * * ... Read More

Asterisks "*" are used in star patterns to represent various shapes, such as triangles, diamonds, hollow shapes, etc. Star patterns are the names for these forms. This tutorial will illustrate how to use C++ to display the left triangle star pattern where the triangle is aligned to the left. Here, we accept as an input the number of lines in the star design. For that many lines, the pattern will be printed. The following table will contain the logic we create to print stars. The following table can help us understand. ... Read More

The purpose of an array is to store a similar type of data in a series of the memory places that can be accessed using base addresses and indexes. We use arrays to hold data for a variety of purposes in many different applications. Finding minimum and maximum elements are a fairly common example of arrays that are needed in several applications including sorting, etc. In this article, we will see how we can find the second-largest element from an array in C++. Understanding the concept with examples Given array A = [89, 12, 32, 74, 14, 69, 45, 12, ... Read More
