  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...

Arrays in C Programming Language (One-Dimensional Array)

 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 functions respectively.


Advantages of using Arrays:

There are various advantages of using arrays to keep in mind, these points include.

We need less amount of code to access or get data.

We can easily traverse or run through the data that is present in an array using the looping statements.

We can also perform various operations on these array variables i.e. we can perform sorting operations on arrays and can also find the smallest and largest values stored in arrays with very less amount of code.

We can randomly get or access the elements of an array.


Disadvantages of using Arrays:

The biggest and the main disadvantage of using arrays is that the size of arrays is fixed we cannot change its size once it is defined.


Simple coding example to understand Arrays in C Programming 




In the above coding example, we simply declared and initialized an array of size five like this int NumArray[5] = {25, 50, 75, 100, 234}; 

After that, we used a for loop with variable i and placed this variable in place of an Array index value like this NumArray[i], so that we could traverse through the entire array and display the values on the console screen.

Like always, Congratulations we have successfully implemented the array coding example.

How if else-if else ladder statement works in C program.

 How if else-if else ladder statement work in the C program. In C programming or any other programming language, there is a concept of control statements or conditional statements. In one of our previous blog posts, we shed some light on the if else statement in the C program. In this post, we will cover the if else-if else ladder statement, which is used when multiple conditions need to be addressed. No, we are going to look at the syntax of the if else-if else ladder statement. Syntax of if else-if else ladder statement if (condition)  { // code to be executed if the condition is true } else if ( condition ) { // code to be executed if the condition is true } else if ( condition )  { // code to be executed if the condition is true } else  { // code to be executed if none of the conditions is true } The if else-if else ladder statement is very similar to the if else statement. The main difference is the addition of an else-if part in it. In the above s...

How to add two numbers in C programming language

  How to add two numbers in the C programming language In this blog post, we will look at how we can use Visual Studio Community 2022 and write C language code to add two numbers. 1) Writing the program: This is a very basic and most important program for beginners. In this program, beginners deal with input and output functions like print() and scanf() for input and output. Let's dive into the coding part: 2) Explaining the coding part: At the start of the code, we can look at two lines starting with #define and #include. The first line is written so we can use print() and scanf() without any safety warning because printf_s() and scanf_s() are now preferred because they are safer to use. In the second line, we use stdio.h header file so that we can use input and output functions i.e., print() and scanf(). The int main() function is the entry point to your C program. It is a necessary function to run your C code. After that, we declared three variables num1, num2, and sum. We...
