C# Conditional Statements
Duration : 00:02:30
if statement:
An if statement is used to conditionally execute a block of code based on a specified condition.Example:
int age = 18;
if (age >= 18)
{
Console.WriteLine("You are an adult.");
}
if-else statement:
An if-else statement is used to execute one block of code if a condition is true and another block if the condition is false.Example:
int num = 7;
if (num % 2 == 0)
{
Console.WriteLine("Even");
}
else
{
Console.WriteLine("Odd");
}
nested if statement:
A nested if statement is an if statement inside another if statement, allowing for more complex conditional logic.Example:
int num = 12;
if (num > 0)
{
if (num % 2 == 0)
{
Console.WriteLine("Positive and even");
}
else
{
Console.WriteLine("Positive and odd");
}
}
if-else-if ladder:
An if-else-if ladder is used when you have multiple conditions to check, and each condition is evaluated sequentially.Example:
int score = 85;
if (score >= 90)
{
Console.WriteLine("A");
}
else if (score >= 80)
{
Console.WriteLine("B");
}
else if (score >= 70)
{
Console.WriteLine("C");
}
else
{
Console.WriteLine("D");
}
switch statement:
Some programming languages have a switch statement for selecting among multiple code blocks based on the value of an expression.Example:
int option = 2;
string result;
switch (option)
{
case 1:
result = "One";
break;
case 2:
result = "Two";
break;
case 3:
result = "Three";
break;
default:
result = "Invalid option";
break;
}
Console.WriteLine(result);
