C# program to find the largest of two numbers:
In this post, we will learn how to find the largest of two user given numbers. We will take the numbers as inputs from the user and print out a message explaining which one is greater or smaller.
We can solve this problem in two different ways. We can use either an if-else block or ternary operator.
With this post, you will learn how to find the largest of two numbers using if-else and ternary operator in C#.
Syntax of if-else and ternary operator:
Below is the syntax of if-else condition:
if(a > b){
}else{
}where, a and b are the numbers that we are taking for comparison. If a is greater than b, then it will run the code that we will write inside the {} after if block. Else, it will execute the code inside the {} after else block.
And, below is the syntax of ternary operator:
(a > b) ? "a is greater than b" : "a is smaller than b"From the texts, you can understand how ternary opertor works. If a is greater than b, than it will return the part after ? symbol. Else, it gets the part after :.
Example of if-else:
Below is the complete example that uses if-else to find the greater number:
using System;
public class Program
{
public static void Main()
{
int first,second;
Console.WriteLine("Enter the first number : ");
first = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter the second number : ");
second = Convert.ToInt32(Console.ReadLine());
if(first > second){
Console.WriteLine("First number is greater than the second number");
}else{
Console.WriteLine("First number is smaller than the second number");
}
}
}Here,
- we are storing the first and the second number in first and second integer variables.
- Using a if-else block, we are checking which number is the largest and based on that we are printing one message.
It will print outputs as like below:
Enter the first number :
12
Enter the second number :
22
First number is smaller than the second number
Enter the first number :
12
Enter the second number :
11
First number is greater than the second numberExample of ternary operator:
Similarly, we can also use a ternary operator to find the larger number and print one message based on it. Below program explains that:
using System;
public class Program
{
public static void Main()
{
int first,second;
Console.WriteLine("Enter the first number : ");
first = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter the second number : ");
second = Convert.ToInt32(Console.ReadLine());
Console.WriteLine(first > second ? "First number is greater than the second number" :"First number is smaller than the second number");
}
}
