-: Relational Operators :-
Operators are those symbols which are used between operands to perform Mathematical and Logical operations.
Relational Operators are those symbols which are used to establish a relationship and compare the values of Two operands.
In the relational operator following symbols are used -
[ <, >, ==, !=, <=, >= ]
_________________________________________________________
see an example of relational operator-
#include<iostream>
using namespace std ;
int main() {
int a=5, b=10 ;
if(a==b)
cout<<"both a and b are equal" ;
else
cout<<"a and b are not equal" ;
return 0 ;
}
_________________________________________________________
Output:- a and b are not equal.
_________________________________________________________
_________________________________________________________
see one another example and compare it with the example given above -
#include<iostream>
using namespace std ;
int main() {
int a=5, b=5 ; //here a and b both are equal.
if(a==b)
cout<<"both a and b are equal" ;
else
cout<<"a and b are not equal" ;
return 0 ;
}
_________________________________________________________
Output:- both a and b are equal.
_________________________________________________________
let's understand that actually what is happening above -
We took two variables named "a" and "b", both of these variables containing integer type data. Now we established a relation (==) between these two variables.
if ( after establishing the relation we gave a condition that if both variables are equal so what to do. we said that if values of both variables are equal so do this ЁЯСЙ simply print a statement "both a and b are equal" in output screen.)
else(after establishing the relation we gave a condition that if both variables are not equal so what to do. we said that if values of both variables are not equal so do this ЁЯСЙ simply print a statement "a and b are not equal" in output screen.)
prog1:- in the 1st program, 5 and 10 are not equal, so we got "a and b are not equal" in the output screen.
prog2:- in the 2nd program, 5 and 5 are equal, so we got "both a and b are equal" in the output screen.
