C++ Program To Find Greater Number. Among Given Three Number

Problem :- Write a C Program for find a greatest number among given three number .ex-you have to given three number ,number may be Integer, Float, Double You Task is to find a Greatest number Input given by User

Logic :- To solve this problem we need to compare all three numbers each other .for better explanation we need three number assume that numbers are 17 ,45 ,56

Step 1 :- First We Compare 17 to 45 and 56 if it is greatest then we can say that 17 is greatest else we go to next step

Step 2:- Then we compare 45 to 56 and 17  if it is greatest then we can say that 45 is greatest else we go to next step

Step 3:- Then we compare 56 to 45 and 17  if it is greatest then we can say that 56 is greatest else we go to next step (Special Case)


Step 4:- This is the last case if all numbers are same or equal then it will print a message that 
" All INPUT ARE EQUAL "

Solution :-

Method 1:-

#include<iostream>
using namespace std;
int main()
{
   /* Program By Ghanendra Yadav

   */
   double num1, num2, num3;

    cout<<"Enter Three Numbers: \n";
    cin>>num1>>num2>>num3;

   if (num1 > num2 && num1 > num3)
      cout<<"\nGreatest Number Is :"<<num1;

   else if (num2 > num3 && num2 > num1)
      cout<<"\nGreatest Number Is :"<<num2;

   else if (num1 > num1 && num3 > num2)
      cout<<"\nGreatest Number Is :"<<num1;
      
   else if ((num1==num2) && (num2==num3) && (num3==num1))
     cout<<"\nAll Are Equal"; 
   

}

Method 2:-

#include<iostream>
using namespace std;
int main()
{
/* Program By Ghanendra Yadav
   Visit http://www.programmingwithbasics.com/
   */
    double num1, num2, num3;

    cout<<"Enter Three Numbers: ";
    cin>>num1>>num2>>num3;

    if (num1>=num2)
    {
        if(num1>=num3)
            cout<<num1<<" Is The Largest Number. ";
        else
            cout<<num3<<" Is The Largest Number. ";
    }
    else
    {
        if(num2>=num3)
            cout<<num2<<" Is The Largest Number. ";
        else
            cout<<num3<<" is the largest number.";
    }
    
    return 0;

}
