To understand the same let us first consider a regular if-else if program:-ĬomparisonResult = " value of a is more than b" ĬomparisonResult = "a and b are both equal in value " Now we shall identify the major use of the conditional operator where it is used as a means to simplify the complex if-else if nests by providing branch or nested criteria of its own which is much less complex when compared to if-else if loop. Result1 = (x > y) ? "value of x is greater than y" : "value of x is less than y" using the Ternary Operator (?:) for the comparison of x and y variable Let us try to replicate the program above using a conditional operator →. The program above illustrates a simple if-else statement that compares the value of two variables x and y and prints a result as per the value assigned to them and upon evaluation of the condition, x> y. Result1 = "value of x is greater than y" Let us first try a regular if else statement:. Let us try to understand the approach to traditional C# programming with the conditional operator. The value of the second and third operand is restricted to the assignment, increment and decrement functions. Also, the compilation time is highly reduced as the conditional operator only evaluates a single operand value expression. the operations are grouped from right to left. The conditional operator follows the right association principle i.e. The other major advantage of the conditional operator is that it translates the compilation flow in terms of branch statements which reduces the use of nested if statement required.

The major use of the conditional operators in C# is found as an alternative for the if-else loop where this is used to reduce the size of the code block. Alternatively, the conditional operators are known as ternary operators or inline if operators. The third operand in the definition contains the definition of the expression in case the conditional result of the first operand evaluates to false. Thus if the return value determined in the first expression is true the second operand is evaluated. The second expression specified before the: symbol and holds the definition or assignment in case the condition defined in the first expression evaluates to true. No specifying a Boolean expression or specifying a faulty expression shall result in a compilation error. Care needs to be taken while defining the expression such that the evaluation condition should always result in a bool result. The first operand is specified before the? and contains the definition of evaluating condition expression.
