What are functions? A function is a collection of statements that accept input, perform some specific computation, and return output. The idea is to combine some frequently or repeatedly performed tasks into a function so that instead of writing the same code for different inputs, we can call the function. Advantages of functions: Code Reusability […]

Storage classes in C++ are type specifiers that aid in defining the lifetime and visibility of variables and functions within a C++ program. C++ storage classes aid in determining the existence of a specific variable or function during the execution of a program. Syntax: Types of storage classes: Five different kinds of storage classes can […]

When encountered, jump statements are used to shift program control from one part of the program to any other part of the program unconditionally. In C++, jump statements are implemented using : continue break return goto continue: Within loops or iterative statements, continue statements are used. The continue statement’s goal is to skip the remaining statements of the current iteration of the loop and proceed to the next iteration. Example: Output: break: The break statement allows us to jump out of the loop instantly, without waiting to […]

In C++ programming language, the repetitive operation is done through loop control instruction. There are three methods by which we can repeat a part of a program. Types of Loops: Entry Controlled Loops: The test condition is tested before entering the loop body in this type of loop. Entry-controlled loops are For Loop and While […]

In real life, we face situations where we must make decisions and decide what to do next. Similarly, the programmer must specify one or more conditions to be evaluated or tested by the program, as well as a statement or statements to be executed if the condition is determined to be true, and optionally, additional […]

sizeof(): The sizeof keyword is a compile-time unary operator that determines the size of a variable or data type in bytes. sizeof() operator is used in different way according to the operand type, i.e, When operand is a Data Type. When operand is an expression. Syntax: Example: Output: Typedef: The typedef keyword allows programmers to create new […]

An operator is a symbol that instructs the compiler to perform particular mathematical or logical operations. C++ has a wide range of built-in operators, including the following: Types of operators: Arithmetic Operators Relational Operators Logical Operators Bitwise Operators Assignment Operator Unary operator Ternary or Conditional Operator Misc Operator Arithmetic Operators: These operators are used on […]

A variable is a name that is assigned to a memory location. It is the fundamental storage unit in a program. In C++, each variable has a type that determines the size and layout of the variable’s memory, the range of values that can be stored within that memory, and the set of operations that […]

A data type specifies the type of data a variable can store, for example, integer, floating point, character, etc. C++ supports the following data types: Primary or Built-in or Fundamental data type Derived data types User-defined data types Primary or Built-in or Fundamental data type: These data types are built-in or predefined data types that […]

A specific template structure is used to write the C++ program. Let us see an example of “Hello World” program. Example: Output: Header Files: The C++ programming language defines several headers, each of which contains information that is either required or useful to your program. The header <iostream> is required for this program. using namespace […]
