  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...

 while loop in c programming language



In computer programming languages there is a concept of control flow statements. In control flow statements we specify some conditions and based on those conditions whether they are true or false we run some iterative piece of code if the condition is true and terminate the control statement if the condition is false. 

There are mainly three types of control flow statements that we use in our programs to get the desired result, these three types of control statements are


Three types of Control flow statements

1) do-while loop

2) while loop

3) for loop


In today's post, we will discuss the while loop control statement. while loop is also known as a pre-tested loop in which before running the piece of code the condition is examined first. If the condition is true only then the while loop will execute and if the condition is false then the while loop statement terminates.

In these control statements, the piece of code is iterated according to the given condition. Now let us look at the syntax of the while loop statement. Below is the syntax of the while loop in c programming.


Syntax of while loop in c program

while(condition)

{

// code to be executed 

}


An expression is given in a while loop if the expression is true code repeats multiple times unless that condition becomes false. Now let us look at the simple example of the while loop. Below is the while loop example,





Explanation of the above coding example

In this while loop example program we simply declared an integer variable with constant value 1. After declaring and initializing this variable we are going to use this variable within the while expression and check for a condition that if the variable number has a value less or equal to 10 while(number<=10) than the given lines of code within curly brackets will repeat or iterate until number is less or equal to 10. At the end of this coding block, we are going to increment or add 1 in this number variable with each iteration until the number becomes equal to 10 and at that point, the while loop will terminate.

Congratulations as always, we did it again, we have successfully executed the while loop in C++ program.

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 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...
