I have a simple C++ question about strings?

I want to do a program that checks the answer of a question. For example:





string ans1;





cout %26lt;%26lt; "How do you spell dog?\n";


getline(cin, ans1);





if(ans1==dog)


{


cout %26lt;%26lt; "correct\n";


}





when I do this program (with other required parts included)


I get errors saying that I need to identify dog, but if I do it skips over the if statement and ends the program

You have to understand the difference between a variable name and a string. In this case, you're asking for a comparison between the answer variable, ans1, and an undefined variable dog.





Now, if you had this statement:





if ( ans1 == "dog" )





you'd get further. Note the double quote marks around dog -- this isn't a variable, but what's called a literal constant.





This would work also if it was before your if statement:





string dog = "dog";





Hope that helps.
Reply:Hi. Hint. I think dog without any quotes (or other demarcation) is a variable, not a string. Not a C++ programmer.
Reply:You can start by asking the user for input. So create an input variable allowing the user to spell dog ( cin %26gt;%26gt; userinput1;) Then compare the results of the user answer to the results of ans1. If(ans1==userinput1)


// If the two answers match that you can use the cout %26lt;%26lt;"correct"\n;
Reply:if(ans1=="dog") or





char ans1[256];





cout %26lt;%26lt; "How do you spell dog?\n";


cin %26gt;%26gt; ans1 ;





if(!strcmp(ans1,"dog")


{


cout %26lt;%26lt; "correct\n";


}
Reply:you are comparing against 'dog' like it is a variable. You should use strcmp(ans1,dog) and check to make sure the value is 0. 0 means the strings are equal. strcmp stands for String Compare.
