Operators in C Language | Part-2

Assignment operator

  1. = operator is called assignment operator.
  2. It is used to move the value or expression result in a variable.
  3. Assignment operator are evaluated from right to left order.

Example of assignment:

  1. a = b = 5, In this example the 5 is assignment in b then b's value is moved to a.
  2. a = b + 5, Assignment operator have the lowest precedence so all other operator are evaluated first and then result is moved to the variable.
  3. 5 = a, This is an error, because in this example we are trying to move the value of variable into constant and constant can't be changed.The same error will be prompted if you are try the expression 6 + b = a.

Compound assignment

+=, -=, *=, /=, %= are called compound assignment operator. It combine the Arithmetic as well as assignment simultaneously.
Compound Assignment Equivalent Expression
a += 5 a = a + 5
a -= 5 a = a - 5
a *= 5 a = a * 5
a /= 5 a = a / 5
a %= 5 a = a % 5
