# Implementing ternary operator without any conditional statement

How to implement ternary operator in C++ without using conditional statements.

In the following condition : a ? b : c
If a is true, b will be executed.
Otherwise, c will be executed.

We can assume a, b and c as values.

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

We can code the equation as :
Result = (!!a)*b + (!a)*c
In above equation, is a is true, result will be b.
Otherwise, result will be c.

## C++

 `// CPP code to implement ternary operator ` `#include ` ` `  `// Function to implement ternary operator without  ` `// conditional statements ` `int` `ternaryOperator(``int` `a, ``int` `b, ``int` `c)  ` `{ ` `    ``// If a is true, we return (1 * b) + (!1 * c) i.e. b ` `    ``// If a is false, we return (!1 * b) + (1 * c) i.e. c ` `    ``return` `((!!a) * b + (!a) * c); ` `} ` ` `  `// Driver code ` `int` `main() ` `{ ` `    ``int` `a = 1, b = 10, c = 20; ` `     `  `    ``// Function call to output b or c depending on a ` `    ``std::cout << ternaryOperator(a, b, c) << ``'\n'``; ` ` `  `    ``a = 0; ` `     `  `    ``// Function call to output b or c depending on a ` `    ``std::cout << ternaryOperator(a, b, c); ` `     `  `    ``return` `0; ` `} `

## Python 3
