That's generally the intention behind homework... you have to do it. Yourself.

No. At least make the effort yourself. Your laziness is not our problem.

Well I am like the best programer in class or at least thats what teachers says . But Im having trouble with this one . And cannot , derive an expresion for it . I cannot if else if . That is forbidden by the teacher . Instead I have to do it with conditional operators which are C++ Exclusive . Im having trouble in this one and one more

 

EDIT : I am also allowed to use the C++ exclusive Logical operators

Welcome to learning. Try it sometime. This is so simple.

Man I seriously need to get the answer . I tryed every thing known to me . Yet I cant do it . My mother knows programing but only in C and not C++ .So I thought I will get help here . Anyone please help me

[madknight3]

The conditional operator (also called ternary operator) is not exclusive to C++, some other languages also have it (just fyi). It's basically just another way to write an if/else statement. Take a look at this tutorial page for them.

Man I know what ternary operators are . All I want is the code which i dont seem to understand that particular one

It's just an If else statement with a read in. How are you out of ideas.

But I cant use If else statement u c . If I was allowed I would have done it . But this is new to me and just dont seem to get it

Then use a ternary as someone else said.

How about you post the code you've tried and we can point out what you're doing wrong.

But how should I use it ???

could u please list the formula code and what type the variables used are

I dont understand whats written in wikipedia . Well the code I have is

 

 

char A , B ;

int college , hostel ;

cout <<"Enter student type A or B" ;

(A:B) ? college==200 : hostel==200 ;

 

is this correct ??? please reply

First : Why do you have two read in variables when you only need one?

Second : You aren't setting those variables equal to anything. You are just checking if they are equal to 200.

Third : Did you read that page? 

(argc > 1 ? a : b) = 1;

Your variable, your operator, your A answer. Then the turinary, if greater than the requirement for A set A = 1, else set B = 1.

condition ? value_if_true : value_if_false

well that I know if conition is true the first expression will evaluate otherwise the 2nd will evaluate . but I dont clearly understand how to use it . Im using c++  for the first time this year 

[Runelight]

What about this one  ,

 

char type ;

int college , hostel ;

cin>>type ;

(type==A)? college=200 : hostel=200

You are asking A or B you only need one variable to do that. 

int A = 0;
cout<<"Enter 1 for Blah, 2 for Yay.\n";
cin>>A;
if(A==1){
	cout<<"Blah.\n";
}
else cout<<"Yay.\n";

OR

cout<<(A==1 ? "Blah.\n" : "Yay.\n");

Omg. Why do you think there is a giant OR.
