The Conditional Operator

The Conditional Operator(?:)

The conditional operator in C is also known as ternary operator. It is called ternary operator because it takes three arguments. The conditional operator evaluates an expression returning a value if that expression is true and different one if the expression is evaluated as false.

#include< iostream>

using namespace std;

int main ()

{

   // Local variable declaration:

   int x, y = 10;

   x = (y < 10) ? 30 : 40;

   cout << "value of x: "<< x << endl;

  return 0;

}

Then the above code is compiled and executed, it produces the following result:

value of x: 40
