Lesson 6-Logic operations, And operation, Or operation, Not Operation - coding overdose

Logic operators in c++

&& - and operator
||- or operator
! - not operator


Program 1:- To find greatest among three numbers


#include <iostream>
using namespace std;
int main ()

{

    int a,b,c;

    cout<<"enter any three numbers a,b,c"<<endl;
    cin>>a>>b>>c;


    if(a>=b && a>=c)
    {
        cout<<"a is greatest number";
    }


      if(b>=a && b>=c)
    {
        cout<<"b is greatest number";
    }



      if(c>=a && c>=b)
    {
        cout<<"c is greatest number";
    }


    return 0;


}

Program 2:- 

The candidate is selected if his age is >= 18 years and height is >=172cm respectively.

#include <iostream>

using namespace std;

int main ()

      if(age>=18 && height>=172)

    {

        cout<<"congrats!! candidate selected";

    }

else    {

        cout<<"sory.. candidate not selected";
