		//AskFamilyInfo(); I won't include this function to make it short...
	return 0;
}

If you run this program after putting in the amount of family members, it skips the question “What is your full name?”

But if I change:

cin >> nNumberOfFamilyMembers; 

to:

getline(cin, nNumberOfFamilyMembers);

and use nNumberOfFamilyMembers as a string instead, everything works fine. But still….I wanted to do it this way. And even so, in the loop I have to change

nNumberOfFamilyMembers

to

nNumberOfFamilyMembers.length

since it would be a string now.

Anything I can do about it?

Every time I use a do while loop and I use eg.:

 string strWhateverString;
getline(cin, strWhateverString);

, the compiler doesn’t wait for any input and skips to the next statements. What would be the problem? If you already answered this question I’m sorry…thank you in advance :)! BTW GREAT TUTORIAL…IT HAS BEEN A LOT OF HELP!

#include <iostream.h>
#include <stdio.h>
#include <string.h>
void Display (char *str)
{
   gets(str);
   puts(str);

}
int main ()
{
	Display("xyzxyz");
	system("pause");
}

assuming that the user enters abcabc, shouldnt str have the value abcabc, instead it runs into memory problems…though turboc++ works just fine.

Won’t this example over write the null terminator?

Also when comparing strings can I just ask if string1==string2 or is there a strcompare function?

I’m a newbie writing my first program and referencing your site.

Thanks,

here is the code:

 #include <cstdlib>
#include <iostream>
#include <string>

int main()
{
    using namespace std;
          cout << "Enter your name: ";
          string strString;
          cin >> strString;
          cout << "Hello, " << strString << "!" << endl;
          cout << "Your name has " <<strString.length() <<
          " characters in it" << endl;
          cout << "The 2nd character is: " << strString[1] << endl;
          strString = "Dave";
          cout << "your name is now " << strString << endl;
          cout << "Hello " << strString << ", Would you like to hear me sing a song?" <<endl;
          string strAnswer;
          cin >> strAnswer;
              if ( strAnswer == "yes" )
                 cout << " \n Daisy, Daisy give me your answer do. \n Im half crazy all for the love of you \n \n";
                 else if (strAnswer == "no")
                      cout << "Ok, Goodbye " << strString << endl;
                      else
                      cout << "I dont understand you " << strString << endl;
system ("PAUSE");

return 0;
