Question:5
C++ program to take a number check and print whether the number is even , odd or zero?
Sol:

#include<iostream>
using namespace std;
int main()
{
	int a;
	cout<<"Enter any no ";
	cin>>a;
	if(a==0)
	cout<<"Number is zero";
	else
	  if(a%2==0)
	  cout<<"Number is even";
	  else
	  cout<<"Number is odd";
	return(0);
}

/* Output */

Enter any no 63
Number is odd

Enter any no 10
Number is even

Enter any no 0
Number is zero

Question:6
C++ program to take input for three number check and print largest number?
Sol:
Method:1

#include<iostream>
using namespace std;
int main()
{
	int a,b,c;
	cout<<"Enter 3 nos ";
	cin>>a>>b>>c;
	if(a>b && a>c)
	cout<<"Max no = "<<a;
	else
	  if(b>c)
	  cout<<"Max no = "<<b;
	  else
	  cout<<"Max no = "<<c;
	return(0);
}

Enter 3 nos 25
96
3
Max no = 96

Method:2

#include<iostream>
using namespace std;
int main()
{
	int a,b,c,m;
	cout<<"Enter 3 nos ";
	cin>>a>>b>>c;
	if(a>b && a>c)
	m=a;
	else
	  if(b>c)
	  m=b;
	  else
	  m=c;
	cout<<"Max no = "<<m;
	return(0);
}

Method:3

#include<iostream>
using namespace std;
int main()
{
	int a,b,c,m;
	cout<<"Enter 3 nos ";
	cin>>a>>b>>c;
	m=a;
	if(b>m)
	m=b;
	if(c>m)
	m=c;
	cout<<"Max no = "<<m;

	return(0);
}

Method:4

#include<iostream>
using namespace std;
int main()
{
	int a,b,c,m;
	cout<<"Enter 3 nos ";
	cin>>a>>b>>c;
	m=(a>b && a>c)?a:(b>c)?b:c;
	cout<<"Max no = "<<m;

	return(0);
}
