How to convert an enum type variable to a string in C++?
Enum is a user-defined datatype in C++ that is used to assign names to integer values. For example, you can use an enum to represent the days of the week from 0 to 6, where 0 represents Sunday, 1 represents Monday, and so on. When you try to access a value of an enum, it will only return an integer value. In this article, we will learn how to convert an enum type variable to a string type variable in C++, so that we can easily display the enum value as a string. Example of Enum: enum color ...
Read Morelldiv() function in C++ STL
The lldiv() function is used to perform division operation on long long integers and return both quotient and remainder. In this article, we will learn how to use the lldiv() function from the Standard Template Library (STL) in C++. What is lldiv()? The lldiv() is a in-built function in C++ that is used to divide one long long integer by another and return the result as a structure that contains both the quotient and remainder. This function is useful when both values are needed after a division operation. The return type of this function is a structure called lldiv_t, ...
Read MoreJava program to check the birthday and print happy birthday message
In this article, we will understand how to check the birthday and print Happy Birthday message. Checking the birthday is achieved by comparing the present day and the given birthday. Problem Statement Write a program that checks if today's date matches a predefined birthday date. If the dates match, the program should print a "Happy Birthday" message otherwise, it should indicate that today is not the birthday. Below is a demonstration of the same − Input Birthday Date: 15 July Output Today’s Date is 20-12-2021 Today is not my birthday Different ways to check the birthday ...
Read MoreHow to implement the Fibonacci series in JShell in Java 9?
In this article, we will learn to implement the Fibonacci series in JShell in Java 9. First, we will learn how the Fibonacci series works, then learn two approaches(iterative and recursive) to implement this sequence in the JShell environment. JShell JShell is a Java shell tool introduced in Java 9 that allows us to execute Java code and print the result immediately. It is a REPL (Read-Evaluate-Print-Loop) tool that runs from the command-line prompt. What is a Fibonacci Series? A number is said to be in the Fibonacci series if each subsequent number is the sum of the previous two ...
Read MoreJava Program to Create Pyramid and Pattern
In this article, we will learn to create pyramid patterns using Java. It will help us to understand how loops work. for loop while loop Java program to create pyramid patterns We are going to print the following pyramid patterns: Half Star Pyramid Inverted Half Star Pyramid Star Pyramid Inverted Star Pyramid Numeric Pyramid Pattern 1: Half Star Pyramid We will initialize the row to 5 and a loop runs from i-1 to i
Read MoreStringize and Token-pasting operator in C
In this article we will see what are the Stringize operator and Token Pasting operator in C. The stringize operator (#) and the token pasting operator (##) are preprocessor operators used within macros for text manipulation. It sends commands to compiler to convert a token into string. Stringize Operator (#) The stringize operator (#) is a preprocessor operator that converts the micros parameter into a string literal. The preprocessor encloses the actual argument passed to the macro in double quotes, effectively convert it into a string. Syntax Following is the syntax of Stringize Operator: #define MACRO_NAME(arg) #arg ExampleIn ...
Read MoreStringStream in C++ for Decimal to Hexadecimal and back
In this article, we will see how to convert a Decimal to a Hexadecimal string and versa in C++. For this conversion, we are using the string stream feature of C++. You can use StringStreams for formatting, parsing, converting a string into numeric values, and more. The Hex is an I/O manipulator. It takes a reference to an I/O stream as a parameter and returns a reference to the string after manipulating it. Implementation of converting Decimal to Hexadecimal In the following example, we will see how to convert decimal numbers or hexadecimal numbers in C++. #include #include ...
Read MoreStack Unwinding in C++
When we call some functions, the call stack stores the address, and after returning, it pops the address to resume work. What is Stack Unwinding Stack unwinding refers to the process of removing function call frames from the function call stack during runtime, wherein local objects are destroyed in the reverse order of their construction. Why Stack Unwinding Occurs? Stack unwinding occurs when an exception occurs in a function and is not handled immediately in that function. The program control goes back through each function step by step, cleaning up any temporary resources used by each function. How Unwinding Works? ...
Read MoreWhat happen if we concatenate two string literals in C++?
In this article, we will explore what happens when we concatenate two string literals in C++. There are two important points to remember when concatenating strings in C++. Concatenation is another property of the string and string literals: let's see the following two properties below: If x + y is the expression of string concatenation, where x and y are both strings. Then the result of this expression will be a copy of the characters of string x followed by the characters of string y. Either x or y can be ...
Read MoreJava Program to Calculate Interest for FDs and RDs using Inheritance
Inheritance is a concept that allows us to access the properties and behaviors of one class in another class. The class whose methods and member variables are inherited is known as the super class or parent class, and the class that inherits these methods and member variables is known as the child class or subclass. In Java, we use the extends keyword to inherit a class. Problem Statement Write Java programs that calculate interest for Fixed Deposits (FDs) and Recurring Deposits (RDs) using inheritance. The program should prompt the user to choose between FD and RD, enter the amount and duration, ...
