Conditional Statement
Learn the conditional statement in C#.
The most commonly used conditional statement in C# is the if statement. It contains a conditional expression and a true branch, and it may contain a false branch. The true branch is executed when the conditional expression is true. The false branch, if present, is executed when the conditional expression is false. The following program demonstrates the use of the conditional statement.
Note: The
truebranch of theifstatement starts the execution after the starting brace{and executes all the statements until the ending brace}.
Syntax
if (conditional statement) // no semicolon here
{
// execution starts from here if the conditional statement is true
//until here
}
else
{
//if the true branch is not executed then this part of the code is executed
//until here
}
We want to write a program that determines eligibility for a driver’s license based on the age input by the user. The eligible age should be or above.
class Test
{
static void Main()
{
System.Console.WriteLine("Enter your age: ");
int age = int.Parse(System.Console.ReadLine()); // Taking input
if (age >= 18) // If age is greater than or equal to 18
{
System.Console.WriteLine("You are eligible for a driver's license.");
}
else
{
System.Console.WriteLine("You are not eligible for a driver's license.");
}
}
}The conditional statement used in the program above ...
