変数Aが10を保持し、変数Bが20を保持すると仮定します-
Operator name | Operator simple | Description | Example |
---|---|---|---|
assignment operator | = | Stores the value to the right of the equal sign in the variable to the left of the equal sign. | A = B |
addition | + | Adds two operands | A + B will give 30 |
subtraction | - | Subtracts second operand from the first | A - B will give -10 |
multiplication | * | Multiply both operands | A* B will give 200 |
division | / | Divide numerator by denominator | B/A will give 2 |
modulo | % | Modulus Operator and remainder of after an integer division | B % A will give 0 |
例
void loop () {
int a = 9,b = 4,c;
c = a + b;
c = a - b;
c = a *b;
c = a/b;
c = a % b;
}
結果
a + b = 13
a - b = 5
a* b = 36
a/b = 2
Remainder when a divided by b = 1
