What are Variables in C++ Programming Laguage

Variables

A variable is a container (storage area) used to hold data. Each variable should be given a unique name (identifier).

int a=2;

Here a is the variable name that holds the integer value 2. The value of a can be changed, hence the name variable.

There are certain rules for naming a variable in C++ Programming Language
1. Can only have alphabets, numbers and underscore.
2. Cannot begin with a number.
3. Cannot begin with an uppercase character.
4. Cannot be a keyword defined in C++ language (like int is a keyword).

How to Solve LeetCode’s Hard Problems Without Getting Stuck

LeetCode’s hard problems can seem daunting, especially when you’re just getting comfortable with coding. Tackling these problems isn’t about innate talent—it’s about persistence, learning, and applying the right strategies. In this blog, I’ll share actionable tips and techniques to help you solve LeetCode hard problems without getting stuck and make consistent progress in your problem-solving journey. Why Are Hard Problems Hard? LeetCode hard problems challenge your understanding of advanced data structures, algorithms, and optimization techniques. Here’s why they’re tough: They require deep problem-solving skills and out-of-the-box thinking. Many involve multiple layers of complexity . Edge cases and large inputs often test your algorithm’s efficiency. They push you to master topics like dynamic programming, graph traversal, and segment trees. However, with the right approach, you can break down even the most complex problems into manageable parts. Start with the Right Mindset Appro...

Efficient Solution to LeetCode 2563: Count the Number of Fair Pairs in C++

 his problem tests our understanding of efficient array traversal techniques and highlights the power of binary search when working with sorted arrays. By the end of this post, you’ll have a clear, optimized solution in C++ that avoids Time Limit Exceeded (TLE) errors and uses two-pointer and binary search techniques . Let’s get started by breaking down the problem and exploring a step-by-step approach to a performant solution. Problem Statement Given: An integer array nums of size n . Two integers, lower and upper . Our goal is to count all pairs (i, j) where: 0 <= i < j < n , and lower <= nums[i] + nums[j] <= upper . Example Walkthrough Let's clarify with an example: Example 1 Input: nums = [0, 1, 7, 4, 4, 5] , lower = 3 , upper = 6 Output: 6 Explanation: Valid pairs that satisfy the condition are (0,3) , (0,4) , (0,5) , (1,3) , (1,4) , and (1,5) . Example 2 Input: nums = [1, 7, 9, 2, 5] , lower = 11 , upper = 11 Output: 1 Explanation: There is only one valid p...
