A pointer is a variable that stores the address of another variable. The deceleration of a pointer is similar to that of a variable the only difference is while declaring a pointer we need to use "*". Following is the syntax to declare a pointer − type *variable_name; Similar to variables, pointers can be declared in different types. Following is an example − #Integer type pointer int *integer_pointer; #Character type pointer char *character_pointer; The following are the points to be noted − Pointers enable direct memory access and manipulation, which is crucial for ...

Loop control statements in C are designed to repeatedly execute operations until a specified condition is met. These Loops continue to run as long as the condition remains true. Loop control statements are used to repeat a set of statements. They are as follows − for loop while loop do-while loop For Loop in C The for loop in C allows us to repeat a set of statements a specified number of times. The for loop includes initialization, condition, and update statements within its syntax. It ... Read More
Type conversions change an expression from one data type to another. conversions can utilize many features of type hierarchies or data representation. Implicit type conversion Explicit type conversion Implicit Type Conversion Implicit type conversions, also known as type casting or type transformation, are automatic type conversions performed by the compiler. Most programming languages have compilers that handle type transformation automatically. When operands are of different data types, the compiler automatically performs implicit type conversions by converting the smaller data type into a larger one. int i, x; float f; double ... Read More
A file is a collection of data stored in secondary memory. The data is entered directly from the keyboard, files are used to store both information and programs. The following operations can be performed on files in the C language − Naming the file. Opening the file. Reading from the file. Writing into the file. Closing the file. File Naming and Opening The syntax for opening and naming file is as follows − FILE *File pointer; For ... Read More
To find difference between sums of two diagonals, we will be discussing two different approaches. We will calculate the sum of the elements present in the left and right diagonal, then we will subtract both sum values to get the difference. In this article we are having a square matrix, our task is to write a JavaScript program to find difference between sums of two diagonals. Example Input: Matrix: [[1, 2, 3], [4, 5, 6], [9, 8, 9]] Sum of left diagonal elements = 1+5+9 = 15 Sum of right diagonal elements = 3+5+9 ... Read More
In this article, we are going to check how we can remove duplicate elements from an array in C# using different approaches. What are Duplicate Elements in an Array? The elements which exist more than once in a given array are duplicate elements. In this problem, we are given an array, and we have to remove duplicate elements and print unique elements. Examples Input: array = {1, 1, 2, 3, 3, 4, 4, 4, 5, 5, 6, 6} Output:array = {1, 2, 3, 4, 5} Explanation: After removing the duplicate elements, the remaining elements are 1, 2, ... Read More
In this article, we are going to discuss how we can check if a matrix is symmetric or not using C#. What is a Symmetric Matrix? A symmetric matrix is a square matrix (matrix which has the same number of rows and columns) in which the element at position A[i][j] is equal to the element at A[j][i] for all i and j. In other simple words, we can say that a matrix is called a symmetric matrix if it is a square matrix that is equal to its transpose. Below are a few examples of understanding a symmetric matrix: ...

To check if a matrix is symmetric, we simply check if the matrix and it's corresponding transpose matrix are equal. A symmetric matrix is a special case of a matrix where both the matrix and the transpose of the matrix are the same (A = A^T). In this article we are given with an array and our task is to write a JavaScript program to check if a matrix is symmetric. Users must be familiar with 2D matrix, transpose of matrix, symmetric matrix, nested loop and if/else statement. Example Input: matrix [A]: [[1, 2, ... Read More
Milliseconds is a smaller unit of time used for problems where precise time calculations are desired. We can easily convert seconds to milliseconds using Python. This is useful in many applications, such as video editing, data analysis, and real-time processing. Problem Description We are given time input in seconds and have to convert it into milliseconds. In this problem, we are going to learn how we can convert seconds to milliseconds in Python. The formula for converting seconds to milliseconds: Milliseconds = Seconds × 1000 Examples Input: 3 Output: 3000 Explanation: We know that, 1 second = 1000 milliseconds, ... Read More
In today's online world, a strong cybersecurity posture is very important. It protects organizational property, records, and operations against the threats. Read this article to learn why it is important to have a robust cybersecurity posture.What is Cybersecurity Posture?Cybersecurity Posture of a company is its total strategy to defend its digital belongings, systems, and records from online threats is called its cybersecurity posture. It consists of the procedures, instruments, policies, and preparations needed to stop, identify, and handle security events.In addition to minimizing vulnerabilities and guaranteeing resilience in opposition to assaults, a robust cybersecurity posture also responds to business norms ...
