1. Introduction

In Ruby, assignment operators are used to assign values to variables. The most common assignment operator is =, but Ruby also supports compound assignment operators that combine arithmetic or bitwise operations with assignment.

2. Program Steps

1. Initialize a variable.

2. Use various assignment operators to modify the variable's value.

3. Print the results.

3. Code Program

# Simple assignment x = 10 puts "Initial value of x: #{x}" # Add and assign x += 5 puts "After adding 5: #{x}" # Subtract and assign x -= 3 puts "After subtracting 3: #{x}" # Multiply and assign x *= 2 puts "After multiplying by 2: #{x}" # Divide and assign x /= 3 puts "After dividing by 3: #{x}" # Modulus and assign x %= 4 puts "After taking modulus 4: #{x}" # Exponent and assign x **= 2 puts "After raising to the power of 2: #{x}" 

Output:

Initial value of x: 10 After adding 5: 15 After subtracting 3: 12 After multiplying by 2: 24 After dividing by 3: 8 After taking modulus 4: 0 After raising to the power of 2: 0 

Explanation:

1. The = operator is the simple assignment operator, it assigns the value on its right to the variable on its left.

2. The += operator adds the value on its right to the variable on its left and then assigns the result to the variable.

3. The -= operator subtracts the value on its right from the variable on its left and assigns the result.

4. The *= operator multiplies the variable by the value on its right and then assigns the result.

5. The /= operator divides the variable by the value on its right and assigns the result.

6. The %= operator takes the modulus of the variable with the value on its right and assigns the result.

7. The = operator raises the variable to the power of the value on its right and assigns the result.
