There are several different types of assignment operators in C++ programming. These operators allow a variable to be assigned with another value or expression. The simple assignment operator assigns the value of an lvalue expression to a variable on its left side. The behavior of all builtin compound assignment operators that take an lvalue expression and a modifiable rvalue expression is the same: the expression is evaluated only once.

Addition

The basic assignment operator is called =. It requires two operands – a variable and the value to be assigned to it. The variables and values must be of the same type for successful operation.

This program adds the value of the right operand to the left one and assigns the result to the x variable. It is also known as Addition Assignment Operator. This program multiplies the right operand with the left one and assigns the product to the x variable. It is also called Multiplication assignment operator in c++.

Subtraction

In C++ programming, the assignment operator is usually associated with moving a value into a modifiable data object, often called a variable. It has two operands – the item to the left is usually an identifier name for the variable and the one on the right is a value.

Examples of assignment operators include addition, subtraction, multiplication and division. They can also perform numeric operations such as increment, decrement and bitwise XOR and shift operations such as binary left and right. The move assignment operator moves the contents of a to another object b, avoiding copying (b is modified). It can be used on class types and non-class types that define an implicit conversion to a class type.

Multiplication

Multiplication is an essential arithmetic operation that's used in many different programming tasks. It's important to understand how to use multiplication in C++ so that you can build software applications efficiently and accurately.

The multiplication assignment operator multiplies the left and right operands and assigns the result to the left operand. The result can be a number, an expression, or a variable. The direct assignment operator expects a modifiable lvalue expression as its left operand and an rvalue expression or braced-init-list (since C++11) as its right operand. It then modifies the lvalue with the value of its right operand. It is also known as the bitwise xor assignment operator.

Division

In this program, we will perform division operation on two values and assign the result to a variable. We will also use other arithmetic operators such as increment and decrement to show how these operations work.

The division operator / divides the dividend (the number divided by the divisor) into the quotient and remainder. The result displayed will depend on the divisibility and datatypes of the operands and results. In a compound assignment operator, the left operand must be modifiable, and the right operand can be either an lvalue expression or a braced-init-list (since C++11). The right operand is implicitly converted to the cv-unqualified type of the left operand if it is not of class type.

Concatenation

Concatenation, also known as string concatenation, is the joining of two or more strings end-to-end to produce a single string. It is a common operation in computer programming and can be performed in a number of ways.

Using the + operator is one way to concatenate strings. This method is simple and straightforward, but it only works with string variables and doesn’t work with String literals (which are always surrounded by double quotes). Another way to concatenate strings is to use the strcat() function. This function takes a destination string and appends a source string to it. The result is a single string that is outputted after executing the program.

Merging

Merging is an operation that combines two data elements into one. It can be used to assign values to variables. The most basic assignment operator is =, which requires a left operand and a right operand. The left operand is usually an identifier name for a variable and the right operand is a value.

The left and right operands must be the same type for successful assignment. This is because the assignment operator moves the value from its right-hand side to its left-hand side. The move assignment operator also avoids copying for class types and remaps the layout of the right operand if necessary, which might degrade performance.
