C++ Program to Count the Sum of Numbers in a String
In this problem, we are given a string containing alphanumeric characters, and the task is to extract all the numbers from the string and compute their sum. The numbers may appear anywhere within the string, and we need to identify them and add them together. In this article, we are going to explore different approaches to solving this problem in C++.Example 1Input: str = "anshu123ayush45anshu"Output: Sum = 174Explanation:The numbers extracted from the string are 123, 45, and 6. Their sum is 123 + 45 + 6 = 174.Example 2Input: str = "1abc2def34ghi56jkl"Output: Sum = 93Explanation:The numbers extracted from the string ...

A capsule is a three-dimensional geometric shape that consists of a cylindrical body with hemispherical ends on both sides. The volume of a capsule can be calculated by adding the volume of the cylindrical part and the volume of the two hemispherical ends present on both sides of the cylindrical part. In this tutorial, we are going to discuss how to find the volume of a given capsule in C++ using different approaches. Formula for Volume of Capsule The formula for the volume of a capsule is as follows: Volume of Capsule = Volume of cylinder + Volume of both ...
Read MoreC++ Program to Print Hollow Square Pattern
When we start learning to code, practicing star patterns is one of the best ways to improve logic building. One of the simplest yet fascinating patterns is the hollow square pattern. In this article, we are going to learn how to print a Hollow Square Pattern using C++. What is Hollow Square Pattern? A hollow square pattern is a geometrical arrangement of stars forming a square shape, but the stars are present only at the boundary of the square. The stars are printed in such a manner that the edges of the square are filled with stars, while the interior ...
