Assignment operators

From cppreference.com
< c‎ | language

Assignment operators are binary operators that modify the variable to their left using the value to their right.


Operator Operator name Example Description Equivalent of
= basic assignment a = b a becomes equal to b N/A
+= addition assignment a += b a becomes equal to the addition of a and b a = a + b
-= subtraction assignment a -= b a becomes equal to the subtraction of b from a a = a - b
*= multiplication assignment a *= b a becomes equal to the product of a and b a = a * b
/= division assignment a /= b a becomes equal to the division of a by b a = a / b
%= modulo assignment a %= b a becomes equal to the remainder of a divided by b a = a % b
&= bitwise AND assignment a &= b a becomes equal to the bitwise AND of a and b a = a & b
|= bitwise OR assignment a |= b a becomes equal to the bitwise OR of a and b a = a | b
^= bitwise XOR assignment a ^= b a becomes equal to the bitwise XOR of a and b a = a ^ b
<<= bitwise left shift assignment a <<= b a becomes equal to a left shifted by b a = a << b
>>= bitwise right shift assignment a >>= b a becomes equal to a right shifted by b a = a >> b
