In this topic, we will discuss Compound Operators examples.
Assume variable A holds 10 and variable B holds 20 then −
| Operator name | Operator simple | Description | Example |
|---|---|---|---|
| increment | ++ | Increment operator, increases integer value by one | A++ will give 11 |
| decrement | — | Decrement operator, decreases integer value by one | A– will give 9 |
| compound addition | += | Add AND assignment operator. It adds right operand to the left operand and assign the result to left operand | B += A is equivalent to B = B+ A |
| compound subtraction | -= | Subtract AND assignment operator. It subtracts right operand from the left operand and assign the result to left operand | B -= A is equivalent to B = B – A |
| compound multiplication | *= | Multiply AND assignment operator. It multiplies right operand with the left operand and assign the result to left operand | B*= A is equivalent to B = B* A |
| compound division | /= | Divide AND assignment operator. It divides left operand with the right operand and assign the result to left operand | B /= A is equivalent to B = B / A |
| compound modulo | %= | Modulus AND assignment operator. It takes modulus using two operands and assign the result to left operand | B %= A is equivalent to B = B % A |
| compound bitwise or | |= | bitwise inclusive OR and assignment operator | A |= 2 is same as A = A | 2 |
| compound bitwise and | &= | Bitwise AND assignment operator | A &= 2 is same as A = A & 2 |
Example
void loop () {
int a = 10,b = 20
int c = 0;
a++;
a--;
b += a;
b -= a;
b *= a;
b /= a;
a %= b;
a |= b;
a &= b;
}
Result
a = 11 a = 9 b = 30 b = 10 b = 200 b = 2 a = 0 a = 0 a = 30
