The document explains assignment operators in programming, particularly in C++. It details the basic assignment operator and various compound assignment operators like +=, which allow for efficient value updates for variables. The document includes example programs demonstrating the use of these operators for modifying integer values.

1. Assignment Operators

2. Arithmetic Operators
 Assignment operators are used to assign values to variables in
programming languages, including C++.
 They provide a concise and efficient way to update the value of a
variable based on a computation or another variable's value.
 In C++, there are different assignment operators available,
including the basic assignment operator (=) and compound
assignment operators (+=, -=, *=, /=, %=).

3. Different Assignment Operators
 Basic Assignment Operator (=): The basic assignment operator is
used to assign a value to a variable.
 It assigns the value on the right-hand side to the variable on the left-
hand side. Here's an example:

4. In the code, different
assignment operators
are used to modify
the value of num1
based on num2 and
display the updated
values.

5. Example
1. Write a program that asks for an integer number, adds 1, and
assigns to the number using the += operator.
Sample Output 1
Enter an integer number: 1
The updated number is: 2
Sample Output 2
Enter an integer number: 2
The updated number is: 3

6. Example
2. Write a program that asks for two integer numbers, x, and y. Then,
add y to x, and assign it to x using the += operator.
Sample Output 1
Enter x: 10
Enter y: 5
Result: 15
Sample Output 2
Enter x: 1
Enter y: 1
Result: 2
