Binary Arithmetic Operators
Division of two integers returns an integer, while remainder is simply truncated:
/* for example: */
7 / 4;
7 * 3 / 4;
/* but: */
7. * 3./ 4.;
Remainder operand % works only with integers; sign of result is equal to the sign
of first operand:
/* for example: */
9 % 3;
7 % 3;
-7 % 3;
We can use arithmetic operators for manipulating characters:
'A' + 32;
'G' - 'A' + 'a';
Unary Arithmetic Operators
Unary operators
(e.g.
When used as prefix, operators
subtract one from the value of operand before the evaluation. When used as suffix,
operators
ation.
For example:
int j = 5; j = ++k;
/* k = k + 1, j = k, which gives us j = 6, k = 6 */
int j = 5; j = k++;
/* j = k, k = k + 1, which gives us j = 5, k = 6 */
