Find greatest of three numbers using nested if else in C++ Language

Introduction: In previous articles i explained How to find greatest of three numbers using multiple if statement and What is For loop in C++ Language? Example program to print counting up to given limit and What is goto statement,its advantages and disadvantages with program example and Get number of days in month,year using nested if and Program to check for vowel or consonant using switch case and Swap two numbers without using temporary variable and Check whether a number is positive or negative using if else and Check whether a number is even or odd using if else and  many other C++ programs. Now in this article i have written a program to find/get greatest/largest of three numbers using nested if else in C++ Language.

Implementation: Let's create a program to get largest of 3 numbers.

#include<conio.h>

#include<iostream.h>

main()

{

      int a,b,c;

      cout<<"Enter first number: ";

      cin>>a;

      cout<<"Enter second number: ";

      cin>>b;

      cout<<"Enter third number: ";

      cin>>c;   

      

            if(a>b)

            {

                     if(a>c)

                     {

                      cout<<a<<"  is biggest number";

                     }

                      else

                     {

                        cout<<c<<"  is biggest number";

                     }

           }       

      else

      {

                     if(b>c)

                     {

                     cout<<b<<"  is biggest number";

                     }

                     else

                     {

                     cout<<c<<"  is biggest number";

                     }

      }

       getch();

      }

• Now run the program using Ctrl+F9

Output:

  Enter first number: 89

  Enter second number: 90

  Enter third number: 6

  90 is biggest number
