If Statement

An if statement, also known as conditional statement, is a method of executing a block of code based on a condition. The syntax of an if statement is the following:

javascript
if(condition) {
// code to execute
}

It takes an expression and executes the code block if the expression is true.

For example:

main.cs

main.cs

copy
using System;

namespace ConsoleApp
{
internal class Program
{
static void Main(string[] args)
{
Console.WriteLine("Before Conditional");
if(10 > 9) {
Console.WriteLine("10 is greater than 9");
}
Console.WriteLine("After Conditional");
}
}
}
12345678910111213141516
using System; namespace ConsoleApp { internal class Program { static void Main(string[] args) { Console.WriteLine("Before Conditional"); if(10 > 9) { Console.WriteLine("10 is greater than 9"); } Console.WriteLine("After Conditional"); } } }

In case the condition is false the code block is ignored:

main.cs

main.cs

copy
using System;

namespace ConsoleApp
{
internal class Program
{
static void Main(string[] args)
{
Console.WriteLine("Before Conditional");
if(10 > 10) {
Console.WriteLine("10 is greater than 9");
}
Console.WriteLine("After Conditional");
}
}
}
12345678910111213141516
using System; namespace ConsoleApp { internal class Program { static void Main(string[] args) { Console.WriteLine("Before Conditional"); if(10 > 10) { Console.WriteLine("10 is greater than 9"); } Console.WriteLine("After Conditional"); } } }
question mark

What is the output of the following code:

int value = 10;

if (value > 5)
{
value = value + 5;
}

if(value == 15)
{
value = value + 5;
}

Console.WriteLine(value);
