Arithmetic Operators in C++
C++ has 5 basic arithematic operators. They are −
- Addition(+)
- Subtraction(-)
- Division(/)
- Multiplication(*)
- Modulo(%)
Example
These operators can operate on any arithmetic operations in C++. Lets have a look at an example −
#include <iostream>
using namespace std;
main() {
int a = 21;
int b = 10;
int c ;
c = a + b;
cout << "Line 1 - Value of c is :" << c << endl ;
c = a - b;
cout << "Line 2 - Value of c is :" << c << endl;
c = a * b;
cout << "Line 3 - Value of c is :" << c << endl;
c = a / b;
cout << "Line 4 - Value of c is :" << c << endl;
c = a % b;
cout << "Line 5 - Value of c is :" << c << endl;
return 0;
}Output
This will give the output −
Line 1 - Value of c is :31 Line 2 - Value of c is :11 Line 3 - Value of c is :210 Line 4 - Value of c is :2 Line 5 - Value of c is :1
There are some compound arithmetic operators also available in c++. The compound arithmetic assignment operators are specified in the form e1 op= e2, where e1 is a modifiable l-value not of const type and e2 is one of the following:
- An arithmetic type
- A pointer, if op is + or –
The e1 op= e2 form behaves as e1 = e1 op e2, but e1 is evaluated only once.
The following are the compound arithmatic assignment operators in C++ −
| Operators | Description |
|---|---|
| *= | Multiply the value of the first operand by the value of the second operand; store the result in the object specified by the first operand. |
| /= | Multiply the value of the first operand by the value of the second operand; store the result in the object specified by the first operand. |
| /= | Divide the value of the first operand by the value of the second operand; store the result in the object specified by the first operand. |
| %= | Take modulus of the first operand specified by the value of the second operand; store the result in the object specified by the first operand. |
| += | Add the value of the second operand to the value of the first operand; store the result in the object specified by the first operand. |
| –= | Subtract the value of the second operand from the value of the first operand; store the result in the object specified by the first operand. |
Let's have a look at an example using some of these operators −
#include<iostream>
using namespace std;
int main() {
int a = 3, b = 2;
a += b;
cout << a << endl;
a -= b;
cout << a << endl;
a *= b;
cout << a << endl;
a /= b;
cout << a << endl;
return 0;
}This will give the output −
5 3 6 3
Note that Compound assignment to an enumerated type generates an error message. If the left operand is of a pointer type, the right operand must be of a pointer type or it must be a constant expression that evaluates to 0. If the left operand is of an integral type, the right operand must not be of a pointer type.
