Check if input contains a certain string.

[robinremue]

I'm new at this but how do I check if the answer on a question contains a certain string.

For example, if the answer on a question is yes, a certain output shows up, if it is not yes, something else shows up.

I got something like:

if (string = "yes") {
                     cout <<  "whatever"; }
else if (string = "no") {
                     cout << "whatever"; }

but ofc it doesn't work and I'm quite sure it can't be this easy...

Thx in advance =)

First of all, you will never know if you are hitting yes or no because they are both the same. Second, I think the curly brackets are in the wrong place. Plus it could make life easier for everyone if you can put the language you are using. C++? C? sorry if I seemed harsh

I'd start out by using == instead of =.

I see nothing wrong with these curly braces: the compiler doesn't care about whitespaces. As for the language, it's obvious: streams are a C++ exclusive.

if (string == "yes") {
                     cout <<  "whatever"; }
if (string == "no") {
                     cout << "whatever"; }

This might be what you are looking for.
= is to set a value.
== is a boolean operator which means "equal to".

And for what I know, there is know "else" in c++

Edit: crap.. enouwee beat me to it See enouwee, I have been learning

== solved the problem! =)

Thank you very much!

Yes there is.

if(string == "yes")
     cout << "You said yes";
else
     cout << "You didn't say yes!";

As a side note, calling your string variables "string" is a bad idea in C++. If the compiler actually allows it, at the minimum in causes much confusion for anyone reading your code.

Yes there is.

if(string == "yes")
     cout << "You said yes";
else
     cout << "You didn't say yes!";
