In C++, the char data type is used to represent a single character, such as a letter, number, or symbol. The char data type is a built-in data type and is always one byte in size. Declaring a Char Variable A char variable can be declared in the same way as any other variable in […]
In C++, strings are not a built-in data type, instead they are a class defined in the standard template library (STL). The C++ string class, also known as std::string, provides a lot of inbuilt functions that make string manipulation very easy. String class objects can be used much like a character array. Creating a String […]
In C++, string concatenation refers to the process of joining two or more strings together to form a single string. There are several ways to concatenate strings in C++, some of the most commonly used methods are discussed below. Using the ‘+’ operator The ‘+’ operator is used to concatenate two strings. The following is […]
C++ provides a wide range of operators that can be used to perform various operations on variables and values. These operators can be classified into several categories, including arithmetic, comparison, logical, and more. Arithmetic Operators Arithmetic operators are used to perform basic mathematical operations such as addition, subtraction, multiplication, and division. The following table lists […]
The if statement in C++ allows you to control the flow of your program based on certain conditions. The basic syntax of an if statement is as follows: if (condition) { // code to be executed if condition is true } The condition in the parenthesis can be any expression that evaluates to a Boolean […]
C++ switch statement is a control flow statement that allows a programmer to choose among multiple options in a program. It is useful when you want to test a single variable against multiple values, and perform different actions based on the result. The switch statement is often used as an alternative to the if-else statement […]
In C++, a while loop is a control flow statement that allows you to repeatedly execute a block of code as long as a given condition is true. It is typically used to execute a certain section of code repeatedly until a certain condition is met. Syntax while (condition) { // code to be executed […]
The for loop in C++ is a control flow statement that allows you to iterate over a sequence of values, such as the elements of an array or a range of numbers. It is a powerful and versatile looping construct that is commonly used in C++ programs. Syntax The basic syntax of a for loop […]
The break and continue statements are used to control the flow of a loop in C++. The break statement is used to exit a loop early, while the continue statement is used to skip the current iteration of a loop and move on to the next one. Break Statement The break statement is used to […]
In C++, there are several ways to loop through the elements of an array. In this article, we will discuss the most commonly used methods for looping through arrays, including the for loop, the for-each loop, and the while loop. For Loop The most basic way to loop through an array in C++ is to […]
