Arrays Practice 3

Let's master the array concept by solving a few more problems on arrays. Problem 1: To find second largest element Write a C++ program to find the second largest element of an array. Input Input size of array: 5 Array elements: 10, 30, 50, 20, 45 Output Second

Basic Functions of String

We already know how functions make our work so simple and organized. Read the 'functions' module if you haven't done so yet. Now we have various functions specific to a string data type that can greatly ease our programming when dealing with strings. To use these

Strings vs Arrays in C++

Strings are sequences of characters used to represent textual data in programming. An array is like a list of items, but each has a specific place. It's similar to lining up a bunch of boxes in a row. You can put things in these boxes (items) and easily

Taking Input in Strings

So far we have used cin to take inputs in C++ but can we take a string input in the same way? Let's see! #include <iostream> using namespace std; int main() { string name; cout << "Enter your name: "; cin >> name; cout

Strings in C++

Sounds like a new term but believe me, we already used strings several times! Let's see the 'Hello World' Program. #include <iostream> using namespace std; int main() { cout << "Hello World"; return 0; } Here "Hello World" is a string

Arrays Practice 2

Ready for another exciting practice session!? Buckle up, gather your tools (pen & paper if required for dry run) and we'll start with the problems 🚀 Problem 1: Insert element in array Write a C++ program to insert an element in an array at the specified position. Input Input

Arrays Practice 1

Hello coders : ) Studying and learning the concepts is an excellent way to have a grasp on them but sometimes or I would say most of the time, practicing problems on those topics helps you to understand the topics way beyond what you expected and even helps us to remember them

Arrays Memory Allocation

Introduction Almost all of the runtime data of a C++ program is stored in RAM. More specifically, if I talk about arrays that we declare/initialise using the way we just learned, and if we do it inside a function, their data is stored in something called the stack memory

Switch Statement Practice

Hello coders : ) Learning and understanding theory is a good way to understand a topic but to get a hold of it, we need practice. Today, in this article we are going to practice a variety of problems upon switch statement. As mentioned in the theory article as well, that switch

Triangular Number Patterns 3

Hello coders! Finally we reached our last article upon pattern problems but you might be wondering that what's going to be different in this? In this article, we are going to learn about triangular patterns consisting of 0s and 1s. If you practiced previous articles then you must

Triangular Number Patterns 2

Hello coders : ) I hope last articles gave you some basic practice upon triangular patterns. In this article we are going to practice a few more problems upon triangular number patterns. But before proceeding towards them remember the 2 key points for number pattern problems: - Decreasing patterns mean decreasing loops

Triangular Number Patterns 1

Triangles and squares might remind you of those typical mathematical chapters that you studied in your school. Hate Maths😠? Not a problem🙂. These questions are more about having fun with patterns and shapes, just like connecting dots to make a picture. Here just knowing about triangles is enough to start

Number Patterns 2

Hello coders : ) I hope you went through previous articles (I am optimistic, I'll take it as a yes 🤭). Till now we solved many questions on star patterns and numeric patterns with 0s and 1s. These were the problems that utilised only 1 or 2 variables in the entire

Number Patterns 1

I hope you got enough practice on star pattern problems and must have understood the role of loops and conditionals there. Star patterns are patterns that uses only a single variable: '*'. Now let's take this pattern game to the next level: Number Patterns 😎 A number pattern

Switch Statement in C++

Life is full of choices and so is programming. Taking your day to day decisions are completely in your hands but in C++ programming, switch statements definitely helps you to take these decisions : ) But wasn't this being already done by the if else ladder?? Yes it was, but

Loops Practice 2

Hello coders : ) I hope you have understood the concept and practiced a few problems on loops by now. Now it's time to move to our new set of problems on loops. So buckle up and let's go 🚀 Problem 1 Write a Program to input a number

Control Flow Practice

Loops Practice 1

Hello coders :) We have completed the concepts and practice problems upon if...else statements and if...else ladder. I hope you had fun doing them! Now it's time to have some practice on our next topic of Control Flow: Loops. Prerequisite: Read the 'while loop' , '

Passing Array in Functions

Hello Coders! We already studied in the last article how to pass Arrays in functions. But do you know that it's not the only way to do that! In this article, we are going to see multiple ways to pass an array into functions: 1. Pass as a

Arrays and Functions

Functions - we already did this topic right! Then why again? 🤔 Well, so far we have only studied simple variables being used or passed as arguments in functions but now we will study how we can use arrays in functions. Let's revise how functions worked: #include <iostream&

Ranged for Loop in C++

We already know how to iterate through arrays using for loops right? But in C++, there's another type of for loop called the ranged for loop through which we can access the array elements very easily. Suppose today's your birthday and you want to distribute toffees

Loops Standard Problems

Till now we learnt many important concepts not only of control flow but of C++ programming as a whole. We did a lot of examples while learning them but now it's time to get our hands on the standard problems. Don't worry they are nothing complex

Taking Input in Arrays

Remember Kirti, Jubin, and Riya's example? If not then let me state it again. Suppose there are 3 students: Riya, Jubin and Kirti. We need to write a program to input their marks and print their average. From what we have studied so far, we know that we

Iterating & Updating Arrays

Iterating Arrays In the last post, we learned what arrays are and how we can create, initialize and access an array. For accessing array elements we printed every element of array one by one manually. Something like this! #include <iostream> using namespace std; int main() { // create an array

Arrays in C++

Before introducing arrays, let me take up a simple question. Suppose there are 3 students: Riya, Jubin and Kirti. We need to write a program to input their marks and print their average. I'd probably create 3 variables, take input, and print the average. Something like this! #include&
