C# Program - Find Largest Number among three Numbers
Three numbers x, y and z are given and the largest number among these three numbers can be found out using below methods:
Example: Using If statement
In the below example, only if conditional statements are used.
using System;
class MyProgram {
static void largest(int x, int y, int z) {
int max = x;
if (x >= y && x >= z)
{max = x;}
if (y >= x && y >= z)
{max = y;}
if (z >= x && z >= y)
{max = z;}
Console.WriteLine("largest number among {0}, {1} and {2} is: {3}", x, y, z, max);
}
static void Main(string[] args) {
largest(100, 50, 25);
largest(50, 50, 25);
}
}
The above code will give the following output:
largest number among 100 , 50 and 25 is: 100 largest number among 50 , 50 and 25 is: 50
Example: Using If-else statement
It can also be solved using If-else conditional statements.
using System;
class MyProgram {
static void largest(int x, int y, int z) {
int max = x;
if (x >= y && x >= z)
{max = x;}
else if (y >= x && y >= z)
{max = y;}
else
{max = z;}
Console.WriteLine("largest number among {0}, {1} and {2} is: {3}", x, y, z, max);
}
static void Main(string[] args) {
largest(100, 50, 25);
largest(50, 50, 25);
}
}
The above code will give the following output:
largest number among 100 , 50 and 25 is: 100 largest number among 50 , 50 and 25 is: 50
Example: Using Nested If-else statement
The above problem can also be solved using nested if-else conditional statements.
using System;
class MyProgram {
static void largest(int x, int y, int z) {
int max = x;
if (x >= y)
{
if(x >= z)
{max = x;}
else
{max = z;}
}
else
{
if(y >= z)
{max = y;}
else
{max = z;}
}
Console.WriteLine("largest number among {0}, {1} and {2} is: {3}", x, y, z, max);
}
static void Main(string[] args) {
largest(100, 50, 25);
largest(50, 50, 25);
}
}
The above code will give the following output:
largest number among 100 , 50 and 25 is: 100 largest number among 50 , 50 and 25 is: 50
Example: Using ternary operator
The ternary operator can also be used here.
using System;
class MyProgram {
static void largest(int x, int y, int z) {
int max = x;
max = (x > y)? ((x > z)? x : z) : ((y > z)? y : z);
Console.WriteLine("largest number among {0}, {1} and {2} is: {3}", x, y, z, max);
}
static void Main(string[] args) {
largest(100, 50, 25);
largest(50, 50, 25);
}
}
The above code will give the following output:
largest number among 100 , 50 and 25 is: 100 largest number among 50 , 50 and 25 is: 50
