Relational operator

Program#1


// If condition is true result is 1 if false result is 0

#include<iostream>

using namespace std;

int main()

{

int a,b;

cout<<"\nEnter a value of a: ";

cin>>a;

cout<<"\nEnter a value of b: ";

cin>>a;

cout<<"condition a>b"<<endl;

cout<<(a>b)<<endl;

// If condition is true result is 1 if false result is 0

cout<<"condition a<b"<<endl;

cout<<(a<b)<<endl;

}

RESULT

Enter a value of a: 12


Enter a value of b: 21

condition a>b

0

condition a<b

1

Conditional operator

Program#1

// If condition is true result is 1 if false result is 0
#include<iostream>
using namespace std;
int main()
{
int a,b;
cout<<"\nEnter a value of a: ";
cin>>a;
cout<<"\nEnter a value of b: ";
cin>>a;
cout<<"condition a&&b"<<endl;
cout<<(a&&b)<<endl;
// If condition is true result is 1 if false result is 0
cout<<"condition a||b"<<endl;
cout<<(a||b)<<endl;
}

OUTPUT


Enter a value of a: 12

Enter a value of b: 32
