The multiplicative operators are −Multiplication (*)Division (/)Modulus or “remainder from division” (%)These binary operators have left-to-right associativity. The multiplicative operators take operands of arithmetic sorts. The modulus operator (%) contains a stricter requirement in this its operands should be of integral type.The multiplication operator yields the result of multiplying the first operand by the second.The division operator yields the result of dividing the first operand by the second.The modulus operator yields the remainder given by the subsequent expression, wherever e1 is that the 1st operand and e2 is that the second: e1 – (e1 / e2) * e2, where both ...

In C++, typedef is a keyword that is used to create a new name for an existing data type. This helps the users to modify the code according to their preference, making it more readable, friendly, and manageable. Syntax Here is the following basic syntax of typedef in C++; typedef existing_type new_name; Here, existing_type is the original data type given in the C++ standard (e.g., int, float, double, etc.)new_name is the new name assigned to that type. Example Here is the following simple example showcasing the use of typedef in C++: #include using namespace std; // Defining ... Read More

Program comments are explanatory statements that you can include in the C++ code. These comments help anyone reading the source code. All programming languages allow for some form of comments.C++ supports single-line and multi-line comments. All characters available inside any comment are ignored by C++ compiler.Single line commentsTo create a single line comment, we use the // notation. Wherever you want to start the comment, start it with //. For example,// This is a comment cout

Bitwise operators are the operators that are used to perform operations on bits of a binary representation of a number.Bitwise OR (|) Operator OR Operator (|) is one of the types of bitwise operators, which compares each bit of the first operand to the corresponding bit of the second operand and returns 1 if at least one of the bits is 1; else 0 if both bits are 0. You can think of it as similar to addition in decimal, like 0 + 0 = 0, and all other combinations result in 1. But this ... Read More

The Bitwise AND (&) Operator is one of the types of bitwise operators, which perform operations on bits of a binary representation. The Bitwise AND (&) compares each bit of the first operand to the corresponding bit of the second operand and returns 1 if both bits are 1, else returns 0 if either or both bits are 0.You can think of it as similar to multiplication in decimal, like 1 * 1 = 1, and all other combinations result in 0. But ensure that both operands are of integral data types (as it works with binary representations) like int, ... Read More

A fundamental or primitive type is a data type where the values that it can represent have a very simple nature (a number, a character or a truth-value); the primitive types are the most basic building blocks for any programming language and are the base for more complex data types.C++ has the following primitive data types −S.NoTypeDescription1boolStores either value true or false.2charTypically a single octet (one byte). This is an integer type.3intThe most natural size of an integer for the machine.4floatA single-precision floating point value.5doubleA double-precision floating point value.6voidRepresents the absence of type.Read More

The XOR operator(^), also known as "exclusive OR", is one of the types of bitwise operators, which compares each bit of the first operand to the corresponding bit of the second operand and returns 1 if both bits are different, else returns 0 if both are the same. This only works with integral data types like int, char, short, long, and unsigned int, etc, and cannot be directly used with float, double, string, and class/struct objects, etc. Syntax Here is the following syntax of Bitwise XOR. result = operand1 ^ operand2; Where operand1 and operand2 are the integral types (like ...

The single operators operate on one quantity and following are the samples of single operators − - The increment ( ) and decrement (--) operators. The compiler distinguishes between the different meanings of an operator by examining the types of its operands.The unary operators operate on a single operand and following are the examples of Unary operators −The increment (++) and decrement (--) operators.The unary minus (-) operator.The logical not (!) operator.The unary operators operate on the object for which they were called and normally, this operator appears on the left side of the object, as in !obj, -obj, and ...

Consider a situation, when we have two persons with the same name, Piyush, in the same class. Whenever we need to differentiate them definitely we would have to use some additional information along with their name, like either the area, if they live in a different area or their mother’s or father’s name, etc.The same situation can arise in your C++ applications. For example, you might be writing some code that has a function called xyz() and there is another library available which is also having same function xyz(). Now the compiler has no way of knowing which version of ... Read More

The unary operators are operators that operate only on a single operand. There are mainly thirteen unary operators in C++, for example, ++, !, ~, typeof, delete, etc.Overloading a unary operator means setting a customized behaviour for the unary operators for the objects of a class. which means you can define how an operator will work when applied to instances of a class instead of using its default behavior. This operator is generally used on the left side of the object, as in +obj, !obj, -obj, and ++obj, but can also be used as a postfix like obj++ or obj--. So, ... Read More
