The operations below apply to both int types and
to double types:
int k;
k = 5 + 10;
Variable k is assigned the value 15 in the last line of code
because the + sign adds the values 5 and 10 together.
int i = 2;
int k;
k = i + 1;
Variable k is assigned the value 3 in the last line of code
because the + sign adds the values 2 and 1 together.
int i = -8;
int k;
k = 1 + i;
Variable k is assigned the value -7 in the last line of code
because the + sign adds the values 1 and -8 together.
int i = 5;
int j = 3;
int k;
k = i + j;
Variable k is assigned the value 8 in the last line of code
because the + sign adds up the values from i and j.
In the above examples, the operator (the + sign) can be
can be replaced with one of the following:
| symbol | elaboration | . |
|---|---|---|
| + | Add | |
| - | Subtraction | |
| * | Multiply | |
| / | Divide | |
| % | Returns the remainder after division. For example: | |
| 7 % 5 = 2 | ||
| 11 % 2 = 1 | ||
| 6 % 2 = 0 |
