Operator Symbol Description Example
Simple assignment = Assigns value to the left operand c = a + b (c = 10 + 30)
operator from right operand will assign the value of c to
a + b (c = 40)
Add AND += Adds the right operand to the left b + = a (b + = 10) is
assignment operand and assign the result to equivalent to b = b + a (b =
operator the left operand 30 + 10) (b = 40)
Subtract AND -= Subtracts the right operand from b – = a (b– = 10) is
assignment the left operand and assigns the equivalent to b = b – a
operator result to the left operand (b=30-10) (b=20)
Multiply AND *= Multiplies the right operand with b *= a (b *= 10) is equivalent
assignment the left operand and assigns the to b = b * a
operator result to the left operand (b = 30 * 10) (b=300)
Divide AND /= Divides the left operand with the b /= a (b/ = 10) is equivalent
assignment right operand and assigns the to b = b / a
operator result to the left operand. (b = 30/10) (b=3)
Modulus AND %= Takes modulus of two operands b % = a (b% = 10) is
assignment and assigns the result to the left equivalent to b = b % a
operator operand (b = 30 % 10) (b=0)
What is Variable Initialization?
To use aria les in programming first e need to create the aria les and assign them a re erence
in the computer memory.
Variable is a storage area which the programs can manipulate by changing the values stored in it.
