Thread: If and char

Another rookie question from Bumfluff:

Is it possible to use characters in if statemnets? ie if myvariable == Y etc.

Thanks

Yep. But, a character literal is written: 'Y'. Note the single quotes.

Ok, single quotes, got it. At first I thought you said not the single quotes but that would be as I just typed it. Is it possible to use a word or sentence?

Use double quotes for strings, which hold 0 or more characters. You should be using the C++ string class for your string variables. If you are, then you can use == like you do with char variables.

If you use C style strings, which are just character arrays with a null character to indicate the end of the string, then you cannot use ==, you have to use a function like strcmp to compare the strings.

I tried a string in my programme but it doesnt work properly:

Code:

#include <iostream>
#include <string>
#include <stdlib.h>

using namespace std;

int main()
{
 string Question = "";
 string LoopStop = "";
 do
 {
 cout<<"Please Ask The Computer A Question:"<<endl;
 getline(cin,Question);
 cout<<endl;
 cout<<"NO!"<<endl;
 cout<<" \n"<<flush;
 cout<<"Would you like to continue? (yes / no *note lower case)"<<endl;
 getline(cin,Question);
 cin.ignore();
 cout<<" \n"<<flush;
 system ("CLS");
 }
 while ( LoopStop == "yes" );
 return 0;
}

Stupid me! The getline Question was a stupid mistake and thanks for the advice.

God I have learned a lot in the two days since I joined this forum.
