How to find volume of different shapes using a menu Now, let's talk about a little bit about this code. You have to write a program which will let you choose what shape's volume you want to find out & after this it will execute for that particular shape to find out it's volume.  So to code this our main target is to build a menu. So how can we do that? It's really simple. We just use a switch case to do this program. BASIC STEPS TO CODE THIS PROGRAM 1. First you should take the integer variable so that we can choose option from this like, Press 1 to find volume of cone, Press 2 to find volume of cylinder & so on. After that we should take float variables to store height, length, radius, width, edge length etc. 2. Next we use a switch case to execute the option driven code. 3. Now we will separately consider each case & make proper formula to find out the correct answer for that specific option selected shape's volume. That's all.  Isn't it so sim...

 7 Benefits of Using Python for Web Development Python is one of the most popular programming languages in the world, and with good reason: it’s easy to learn, it’s fast, and it’s incredibly versatile. This makes it ideal not only for web development, but also for big data analysis, scientific computing, mobile apps, data science—the list goes on and on. However, there are still some lingering questions as to why you should choose Python over its competitors like PHP or Ruby, so here are seven reasons that will hopefully convince you to use Python in your next web development project. 1) Python code is easy to read Developers who use Python are forced to create code that is easier to read, thereby boosting productivity. But unlike with other programming languages, developers using Python don’t have to worry about formal training or memorizing syntax. For example, in order to add two numbers together in C++, a developer must remember that += means addition. However, in Python, + den...

 C code to calculate product of even digits of a given number Code Steps: 1. First input the number 2. Now initialize a variable =1, that stores the multiplication  3. Now start a while loop until number = 0 4. Inside while loop just find out all the digits by finding the remainder & check it if it is divisible by 2  5. If the number is divisible by 2 then multiply that number with the variable that was initialize = 1 6. At last return the multiplication storing variable.  C Code Snippet #include <stdio.h> int main (){     int num ;     int product = 1 ;     printf ( "Enter the number: " );     scanf ( " %d " , & num );     int temp = num ;     while ( num != 0 ){                 int digit = num % 10 ;         num = num / 10 ;         if ( digit % 2 == 0 ){         ...

 C code for two numbers to check if they are co-prime or not Question: How can we understand if two numbers are coprime or not? Ans:  A Prime Number is defined as a Number which has no factor other than 1 and itself. But, Co-prime Numbers are Considered in pairs and two Numbers are  Co-prime  if they have a Common factor as 1 only . Their HCF is 1. Now come to the main point that is how to code it in C language so that we can get the correct output. C code snippet: #include <stdio.h> int main (){     int num1 , num2 , hcf ;     printf ( "Enter the first number: " );     scanf ( " %d " , & num1 );     printf ( "Enter the second number: " );     scanf ( " %d " , & num2 );     for ( int i = 1 ; i <= num1 ; i ++ )      {       if ( num1 % i == 0 && num2 % i == 0 )       {         hcf = i ;       ...

 10 Tips for Writing Faster and More Efficient Code Writing efficient code may seem like an impossible task when you’re just starting out with your programming journey, but the truth is that there are several steps you can take to make your code run faster and use fewer resources. You don’t have to be some sort of genius or even have years of experience to achieve this – here are 10 simple tips for writing more efficient code! 1) Use Type Alias When you need to define your own data type, consider using a type alias. This saves you from having to repeatedly reference more verbose names like String or NSNumber. Using a type alias also helps reduce pollution of existing types, which can cause problems later on. For example, adding an int property on top of NSObject will break a lot of code that uses that class without changing its definition. 2) Use Option Auto or Type Keywords Most developers have different preferences, but it is important to use Option Auto or Type Keywords. This wi...

 3 C++ Features That Make It a Superior Language C++ has come to dominate the world of Object Oriented Programming, while also maintaining its status as one of the top computer languages overall. It’s easy to see why that’s the case. Though it isn’t the most beginner-friendly language, it does offer an array of powerful features that make it stand out from other programming languages in important ways that are worth considering before making a decision about which language to use for your next project or application development task. 1) Object Oriented Programming Object-oriented programming (OOP) is a programming paradigm that emerged in the 1960s, mostly with Smalltalk and Simula. The principal concepts behind OOP are: information hiding, encapsulation, polymorphism and inheritance. These features improve code reuse, make maintenance easier and reduce complexity of programs. When we talk about object oriented programming in C++ we refer to how classes and objects communicate toge...

Programming, Expectation vs Reality Learning to code can be very rewarding, as well as highly marketable. But how does the reality of coding stack up to the image you have in your head? Does it really require non-stop focus and no social life? Are you really going to be chained to your computer working on a project all weekend? Can you really build an app without knowing any programming languages? The answer to each of these questions is no, not necessarily. Attitude When learning a new skill or trying out a new hobby, it’s easy to feel intimidated. Whether you’re just learning how to code in JavaScript or going through MIT OpenCourseware for an upcoming architecture class, it can be hard not to compare yourself with others—especially those who seem particularly skilled at what they do. But here’s something worth remembering: It takes time and practice to master any skill. Keep that in mind next time you find yourself feeling discouraged by your progress or comparing yourself with othe...

 Important Coding Questions (With C Language + Code Snippet) Source: Click This Link Definition of Armstrong Number:  What is an Armstrong Number?

 The First Programming Language You Should Learn What’s the first programming language you should learn? While it depends on your goals, experience level, and future career plans, certain languages are better than others depending on where you want to take your programming skills. In this article, we’ll take a look at four popular programming languages (C, C++, Java, Python, PHP, and JavaScript) to help you find the one that’s right for you! C It’s a very low-level language, which means it won’t necessarily be easy to program in C if you don’t have prior experience with computer science. But that doesn’t mean you should avoid it! Because C is so low-level, writing code in C tends to be faster than many other languages. And because of its ubiquity on Windows and Unix systems, it also makes an excellent default choice if you want to get started with programming but aren’t sure what language to use first. In addition, many programmers feel that low-level languages like C give them mor...
