C++ LANGUAGE ARITHMETIC OPERATORS

Arithmetic Operators 

There are following arithmetic operators supported by C++ language: 
Assume variable A holds 10 and variable B holds 20, then: 



Operator  Description                          Example 
+         Adds two operands                  A + B will give 30 
-         Subtracts second 
               operand from the first                  A - B will give -10 
*         Multiplies both operands          A * B will give 200 
/         Divides numerator by de-numerator  B / A will give 2 
%         Modulus Operator and remainder 
               of after an integer division          B % A will give 0 

++         Increment operator, 
               increases integer value by one          A++ will give 11 
--          Decrement operator, 
               decreases integer value by one          A-- will give 9 

Try the following example to understand all the arithmetic operators available in C++. 
Copy and paste the following C++ program in test.cpp file and compile and run this program. 
#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 ; 
   c = a++;  
   cout << "Line 6 - Value of c is :" << c << endl ; 
   c = a--;  
   cout << "Line 7 - Value of c is  :" << c << endl ; 
   return 0; 
} 
When the above code is compiled and executed, it produces the following result: 
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 
Line 6 - Value of c is :21 
Line 7 - Value of c is  :22
