Arithmetic operator :
There are
five arithmetic operators which are used in C++ programming. They are:
For doing
basic arithmetic through C++, you need to know about the functions of these
arithmetic operators.
The function
of all operators does same as those are used in mathematics, except modulus (%)
operator. It is used for finding the reminder.
Reminder
example:
#include
<iostream>
using namespace std;
int main()
{
int x;
int z;
int reminder;
int y;
cout <<"enter a number = ";
cin >> x;
cout <<" enter another number by
which you are going to divide = ";
cin >>z;
y = x / z;
reminder = x % z;
cout << " after division =
" << y <<endl;
cout << " reminder =
"<<reminder <<endl;
return 0;
}
and the
output will be…
·
Compound assignment:
Compound assignments are simply the short form of some arithmetic
operators. Some of the compound assignments are given below:
Expression

Equivalent to

A += 5

A = A + 5

A  = 5

A = A – 5

A *= 5

A = A * 5

A /= 5

A = A / 5

A %= 5

A = A % 5

A >>= 5

A = A >> 5

A <<= 5

A = A << 5

Example
program:
#include
<iostream>
using namespace std;
int main ()
{
int a;
int b;
cout << "enter a number =
";
cin >>a;
a +=2;
b =a;
cout << b;
return 0 ;
}
And the
output will be…
·
Increase and decrease:
Shortening
even more some expressions, the increase operator (++) and the decrease
operator () increase or reduce by one the value stored in a variable. They
are equivalent to +=1 and to =1, respectively.
Expression

Equivalent to

A++ or ++A

A = A + 1

A   or   A

A = A  1

Example
program:
#include
<iostream>
using namespace std;
int main ()
{
int a;
cout << "enter a number =
";
cin >>a;
a++;
cout << a << endl;
return 0 ;
}
And the
output will be…
·
Rational and equality operators:
To evaluate
a comparison between two expressions we can use the rational and equality
operators.
Expressions

Meaning

==

Equal to

!=

Not equal to

>

Greater than

<

Less than

>=

Greater than or equal to

<=

Less than or equal to

If you have
Microsoft Visual C++ or any other compiler installed in your computer, you can
just check the above programs.
