C has special shorthand that simplifies coding of certain type of assignment statements.
Example
a = a + 2;
can be written as
a + =2; compound assignment statement
This operator += tells the compiler that a is assigned the value of a+2.
This shorthand works for all binary operators in C.
General form:
<variable> < operator> = <variable/constant/expression>
| Operator | Example | Meaning |
| += | a+=2 | a=a+2 |
| - = | a-=2 | a=a-2 |
| *= | a*=2 | a=a*2 |
| /= | a/=2 | a=a/2 |
| %= | a%=2 | a=a%2 |
| &&= | a&&=c | a=a&&c |
| ||= | a||=c | a=a||c |
