COMPOUND ASSIGNMENT EXPRESSIONS
Increment and decrement operators abbreviate certain kinds of assignments. C++ also allows the assignment to be combined with other operators. The general syntax for these combined assignments is
variable op= expression
where op is a binary operator. The effect of the combined assignment is the same as
variable = variable op expression
For example, the combined assignment
n += 8;
has the same effect the simple assignment
n = n + 8;
It simply adds 8 to n.
EXAMPLE : Assignment Operators
This shows how to use some of the combined operators:
#include <iostream.h>
// Tests combined operators:
main ()
{
int n = 44;
n += 9;
cout << n << end1;
n -= 5;
cout << n << end1;
n *= 2;
cout << n << end1;
return 0;
}
53
48
96
The statement n += 9 adds 9 to n, the statement n -= 5 subtracts 5 from n, and the statement n *= 2 multiplies n by 2.
