  How To Write a Hello World Program In C++ Programming Language In this post we will look at how a C++ program works. We will try make the example as simple as possible for the beginners so they can easily understand the basics of C++. We will write a simple C++ hello world program in C++ programming language which is considered as the very first program in almost every programming language. A Brief Introduction to the C++ Programming Language C++ is an object oriented programming language and it is an extension to C programming language. C++ is a general purpose programming language and it is also a case-sensitive language. C++ is very powerful programming language it has features of both low level and high level programming languages, and that is why it is called mid level programming language. Hello World program in C++ programming language Above is an example of a simple Hello World program in C++ programming language. Now let us look at the code, and I will take you...

What is File Handling in the C Programming Language

  What is File Handling in the C Programming Language In programming languages, we sometimes encounter situations where we need to store data from a program. Sometimes, it is not enough to just create data during program execution and lose it as the program stops. So, in such situations, we need to store data at some permanent location so that we can access it later on and perform certain operations on it. These operations include creating a new file, opening a file, reading from a file, writing to a file, and deleting the file. From here the concept of file handling comes into the picture. This file handling helps us to store the data permanently and then perform various operations on that stored data and use that data for other important purposes. So in simple words, a file is a location or container in computer storage devices for storing the data. How to work with files in the C programming language In C programming language we can perform different functions on a file. We can ...

How to use Structures in C Programming Language

  How to use Structures in C Programming Language In programming languages like C, C++, C#, etc., sometimes we encounter a situation where we need to store different variables with different datatypes, but these variables are related to one object or instance. In such situations, we use data structures. Today, we are going to discuss a simple technique that will help us store related variables in one place, namely, structures. We will look at how structures are used in the C programming language to help us achieve our target. What is Structure in C Programming Language We can consider structure as a special type of data structure that we can use to store data related to an entity under one umbrella and we can call it structure. We can consider a structure as a user-defined data type and it allows us to store various data types in one place. In structures, each data member used inside the structure body is called a member of a structure. How we can create a Structure In C programmin...

Arrays in C Programming Language (One-Dimensional Array)

Image
  Arrays in C Programming Language (One-Dimensional Array) In today's blog post, we will explore one of the fundamental data structures known as arrays. Arrays play a vital role in a programming language, they allow us to use a single variable that can store multiple values of the same data type. And thus we don't need to make separate variables to store different values. Another important point to keep in mind is that in arrays the elements or values are stored in contiguous memory locations. And also the starting index of arrays is zero. Why do we use Arrays? One of the most important points that we already discussed is that arrays can store multiple values in a single variable.  Also, we can use looping statements in order to traverse through arrays and can also process the data easily. We can also manage the memory easily and efficiently. Another very important point to keep in mind is that we can also send and receive large collections of data to and from functio...

What is Call by Value and Call by Reference in C Programming

What is Call by Value and Call by Reference in C Programming We use functions in programming languages like C, C++, C#, etc. Today we will cover some important concepts about functions that are implemented in C programming language. The topic we will cover today is the functions and the use of call by value and call by reference in C programming. This is a very important topic for functions. As we all know when we use functions we can pass values to functions from within the main program, the point where we call a function. There are two ways to pass data to functions in C language i.e.: Call by value and Call by reference . What is Call by value in C programming In Call by value, we pass the values of parameters or arguments that are used inside the main program. We only send variables' values to the function parameters. As shown in the above coding example, we cannot modify or change the values of parameters that are used inside the main program. In the...

How to use functions in C programming Language

-
Image
  Functions in C Programming Language In programming languages, there is a concept of functions that we use to implement some functionality in our code. Functions help us reuse the code and enhance its performance, as they are written once and tested again and again. In C  programming we can use functions to break the code into smaller pieces that are easily maintainable. A function is a piece of code that is enclosed in curly brackets, and a function only runs and executes when it is called within a main program in C programming language. We can also pass data from our main program or function to any user-defined function. As we already discussed, the main advantage or benefit of functions is reusability. In functions, we can define the code once, and after that, we can use the function code many times, which enhances the reusability of the code. We can also refer to functions as procedures or sub-routines in some programming languages. Basically when we run a C program t...

Nested Loops in C Programming Language

  Nested Loops in C Programming Language In programming languages, we have control statements or looping statements which are the following, 1) while-loop 2) do-while loop 3) for loop we have seen loop implementation one at a time i.e., one loop type implemented in the program. Now we will look at how to use the nested loops in the C programming language. The first thing to keep in mind is what we mean by the term nested loop. The main idea behind nested loops is to place a loop inside another loop. In this article, we are going to look at nested for loops in the C programming language. As we previously discussed we can use a loop inside another loop. So today we are going to look at how we can use a for loop inside another for loop .  Remember that if we have two for loops one for loop inside another for loop, and if both the loops are set to three iterations, then for each iteration of the outer loop the inner loop will execute three times i.e. if the outer loop runs ...
