ARITHMATICAL OPERATORS IN C++

There are following arithmetic
 operators supported by C++
language

Arithmetic Operators: 

The use of arithmetic operators in c++ programming language must include care to avoid unclear statements.

let consider the following examples;
The % modulus operator will divide the first given number by the second given number and return the remainder of the operators.
Let's take a look at the program below and execute it to see the out for ourselves.
#include<iostream>
When the above code is compiled and executed, it produces the following result: 

      a = b * c - d % e / f ;                    // this is unclear                    

       a = (b*c) - ((d % e) / f);              // this is clear                        

This is useful to determine if a number has an odd or even value

The ++ increment operator and -- operator alter the given value by and returns the resulting new value. These are most commonly used to count iterations in a loop. The ++ mainly increases a value by one either before it is used in the program line or after.

They can both be placed before(prefix) or after(postfix) the operand. if  ++ or -- is placed before the operand, it immediately changes the value before it is used in the program.

On the other hand, placing it after the operand, the value is used first and increment or decrement by is added to the result.

 usingnamespace 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 ; 

   c = a++;   

 cout <<"Line 6 - Value of c is :"<< c << endl ; 

   c = a--;   

 cout <<"Line 7 - Value of c is  :"<< c << endl ;

 return0;

 } 

Line1-Value of c is:31

 Line2-Value of c is:11

 Line3-Value of c is:210

 Line4-Value of c is:2

 Line5-Value of c is:1

 Line6-Value of c is:21

 Line7-Value of c is:22
