  Passing array to function in C++ programming language Last updated on : October 27, 2026 In todays blog post we are going to cover the merge of two very important concepts in C++ programming language. Today we are going to merge functions and arrays in a C++ program. And we will study that how we can pass an array to a function in C++ program . We know that functions are reusable block of code with the help of which we can perform some important task as per our programming logic. With the help of functions we can break large programs into smaller, and more manageable segments, which we can use many times as our programming need or logic. Now let us talk about arrays in C++ programming language. We know that arrays are also variables which can hold multiple, fixed size collection of data items or values with same data type. The main advantage of arrays is that we don't have to create multiple variables for each value of same data type. And we can access eleme...

  Two dimensional or 2d arrays in C++ programming language Last updated on : October 24, 2026 In todays blog post we are going to cover a very important concept with respect to arrays in C++ programming language. This concept is about two-dimensional arrays in C++ program. Two-dimensional arrays are also referred as 2d arrays and they are basically array of arrays . We can simply store data in two-dimensional arrays or 2d arrays in a grid like structure which consists of rows and columns . And keep this one important point in your mind that in 2d arrays , again the starting index for both rows and columns is 0 (zero). It means that if you want to access the first element of 2d array you have to put 0 in both rows and columns square brackets like this, string words[2][2] = { { "hello" , "World" },{ "good" , "bad" } }; cout << words[0][0] << endl; In this way we can access the very first element or value...

Arrays In C++ Programming Language Last updated on : October 22, 2026 In todays blog post we are going to cover a basic data structure used in C++ programming language, which is known as arrays. So what is arrays and what is the use of arrays in C++ programming language. Array is a basic linear data structure. And it is a collection of elements of same data type and these elements or values are stored at the contiguous memory locations or addresses. And we can access the elements of array by using the index of any specific element or value with in the array body. If at this point things are not clear to you, don't need to worry we will cover the examples in C++ programming language that will help you all in understanding the concept of arrays C++ programming. If we talk about the main use of arrays in C++ programming language, which is, instead of declaring separate or multiple variables for each value, we can use arrays to store multiple related values ...

What is Recursion in C++ programming language Today in this blog post we will cover the concept of Recursion in C++ programming language for  beginners. So what is Recursion? And what is the use of Recursion in programming languages? We will cover the answer of these questions shortly. For now let us look at the basic introduction of Recursion. Recursion is a concept in which the function calls itself with in its own body, and breaks the complex problems into smaller and more manageable parts. So the first question was what is recursion? Basically Recursion is a method or technique which is used in programming languages and in this method the function calls itself. It means the function is called with in its own body. We will cover this concept with simple programming example which will make the concept of recursion crystal clear to the audience. The Second question was what is the use of Recursion in programming languages? Recursion simply breaks down comp...

  Call by value and call by reference in C++ programming language Today we are going to talk about functions in C++ programming language. We will cover the concept of call by value and call by reference in C++ program. Before diving deep into this topic we will look at little introduction of functions in C++ program. By now we know that functions are one of the most important aspect of any programming language and the same is true with respect to C++ program. They are very important building block of C++ program. With the help of functions programmers and developers can divide a program into smaller and manageable parts. With in functions there is a concept of call by value and call by reference. Now we will understand and have a look on this important concept regarding functions. In functions we have studied about that how we can call a function in the main() method. In C++ we use arguments and parameters to send and receive data during function call respectiv...

Functions And Parameters In C++ Programming Language We have studied about functions in our previous blogs, but now we will discuss about parameters and arguments in functions in C++ programming language. We know that functions are reusable blocks of code that executes specific tasks. Now we will look at the use of functions along with the parameters. The first questions should be that what is a parameter? In simple words we can define paramteres as placeholder variables inside the function round brackets to accept external data inputs . And the main purpose of parameters is to hold the data passed to the functions, by functions calling. Before going deep into functions remember that functions are one of the most important building blocks in C++ programming. So in simple words we can say that information or data can be passed to functions as an argument, and these parameters act as variables inside the function. Basic syntax and working...

  Functions In C++ Programming Language Today we are going to look at the use of functions in C++ programming language. We use functions to repeat or reuse some piece of code in our program. So a function in C++ is a reusable block of code that executes when it is called.  Functions are the most important building blocks in C++, or any other programming language. These funtions allow the developers to divide or break a large program into smaller and manageable segments or parts. With the help of these functions we can reuse the same lines of code again and again or multiple times without need to write these lines of code multiple times. Each and every function is used to perform some specific task. These functions are  also referred as procedures or subroutines in different programming languages. We use these functions to achieve modularity in our program. Modular programming means breaking program into smaller independent parts (modules) so it is ea...
