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...

Switch statement in c programming language
What Is a switch statement?
The switch statement is a conditional statement that we use to run different code sections based on some conditions. The switch statement also works like the if else-if else ladder statement. As we know in the else-if ladder statement we implement multiple conditions it is exactly how the switch statement works. In the switch statement, we use the term case: that tells us about any specific condition within the switch expression area switch(expression).
What is the syntax of a switch statement in c programming
switch(Some_Epression)
{
case value1:
// insert code here
break;
case value2:
// insert code here
break;
default:
// insert code here
}
Rules and regulations of switch statement:
Always remember that the expressions that are used within the switch statement i.e. switch(expression), this expression must be a single character or an integer value. As discussed earlier case: statements are used in switch statements, these cases must be an integer or a single character. At the end of each case coding block, we use a break statement.
It is not mandatory to write a break statement but it Is a good practice to use a break statement, because if there is no break statement used between different cases then all cases will run or be executed one by one.
What is the default keyword in the switch statement:
We use this default keyword at the end of the switch statement. This default keyword works in the same way as the else statement works in the if else-if else ladder statement. In switch when no case is true then at-last the default case runs and executes some piece of code.
Example of switch statement:
In the above coding example, the main scenario is that we have a variable that we named as num and the datatype of this variable is int.
We assigned the value of 2 to this num variable. Then we used this num variable inside the switch statement.
Now three case statements are used with integer values like 1, 2, and 3 i.e. case 1:, case 2:, and case 3: are used in the above given piece of code.
case 1: means that if the value of the num variable is 1, then run case 1: code, and the same applies to the other two cases with respect to their values.
And if we notice break statement is used between each case to execute only one case at a time.
At last, a default statement is used which will execute if none of the cases are true.
Congratulations you have implemented the switch statement with an example.
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...
