unwanted blankness

Ok cross everything out, I got it to check the error, it checks it, if its <=1 or >3 then it goes back to wanting to know what the string is but if it is a correct answer it just goes to a blank line

Code:

---

#include <iostream>
#include <string>

using namespace std;

int main()
{
    int X;
    X=1;
    while(X=1)
    {
        char option[3];
        cout<<"Are you going to want to loop?\nYes or No: ";
        cin>>option;
        if(sizeof(option)<=1)
        {
            cout<<"Now why are you trying to enter something too tiny (pun intended) ;-)";
            cin.get();
        }
        if(sizeof(option)>3)
        {
            cout<<"This isn't the time for buffer overflows yet";
            cin.get();
        }
        else
        {
            if(strcmp(option,"Yes")==0||strcmp(option,"yes")==0)
            {
                char buffer[10];
                cin>>buffer;
                cout<<buffer;
                cin.ignore();
                cin.get();
            }
            if(strcmp(option,"No")==0||strcmp(option,"no")==0)
            {
                char buffer[10];
                cin>>buffer;
                cout<<buffer;
                cin.ignore();
                cin.get();
                X=0;
            }
        }
    }
    cin.get();
    return 0;
}

Code:

---

>            if(strcmp(option,"Yes")==0||strcmp(option,"yes")==0)
>            {
>                char buffer[10];
>                cin>>buffer;

---

cin >> buffer;
Can you rephrase your question? cin stands for console input. So this line waits for the user to enter something.

Yeah just saw that :-P, Thanks, stupid mistake ^.^

Ok but now for every error, its saying same size as yes, but not yes.... instead of me entering KK and it saying same size as no, but not no :(

Code:

---

#include <iostream>
#include <string>

using namespace std;

int main()
{
    int X;
    X=1;
    while(X=1)
    {
        char option[3];
        cout<<"Are you going to want to loop?\nYes or No: ";
        cin>>option;
        if(sizeof(option)<2)
        {
            cout<<"Now why are you trying to enter something too tiny (pun intended) ;-)";
        }
        if(sizeof(option)>3)
        {
            cout<<"This isn't the time for buffer overflows yet";
        }
        if(sizeof(option)==3&&!(strcmp(option,"yes")==0||strcmp(option,"Yes")==0))
        {
            cout<<"Tisk tisk, you tried to fool me by entering something the same size as yes, but not yes.\n";
        }
        if(sizeof(option)==2&&!(strcmp(option,"No")==0||strcmp(option,"no")==0))
        {
            cout<<"Tisk tisk, you tried to fool me by entering something the same size as no, but not no.\n";
        }   
        else
        {
            if(strcmp(option,"Yes")==0||strcmp(option,"yes")==0)
            {
                char buffer[10];
                cout<<"Ok, now try to overflow me\n";
                cin>>buffer;
                cout<<buffer;
                cin.ignore();
                cin.get();
            }
            if(strcmp(option,"No")==0||strcmp(option,"no")==0)
            {
                char buffer[10];
                cout<<"Ok, now try to overflow me\n";
                cin>>buffer;
                cout<<buffer;
                cin.ignore();
                cin.get();
                X=0;
            }
        }     
    }
    return 0;
}

and if i type no it says the yes error but brings me to the overflow point
eDIT: Ahhh, should change to two first ||'s to &&'s

> while(X=1)
Remember = is assignment, and == is equality:

Code:

---

    while(X==1)

---

> char option[3];
Remember this can only hold two characters plus the string terminator. So if you want it to hold "yes", it needs to have 4 elements:

Code:

---

        char option[4];

---

> if(sizeof(option)<2)
Instead of sizeof, use strlen() to find a char array's length:

Code:

---

        if(strlen(option)<2)

---

To use strlen(), include <cstring>.

Why not use the string class instead. Then you can do stuff like:

Code:

---

  string option;
.
.
  if (option.length() < 2)
  {
.
.
  else
  {
      if (option == "Yes" || option == "yes")
      {

---

How do we use the string class?

Try the tutorials.

Use = for assignment and + for concatention.

Code:

---

string firstname = "joe";
string lastname = "smith";
string fullname = firstname + " " + lastname;

THANK YOU!!! That made life so much easier but now it checks it, but loops anyway if you say no and it doesnt give the error messages

Code:

---

#include <iostream>

using namespace std;

int main()
{
    int X;
    X=1;
    while(X=1)
    {
        string option;
        cout<<"Are you going to want to loop?\nYes or No: ";
        cin>>option;
        int Y;
        int Z;
        Y=0;
        while(Y>0)
        {
            Z=Y;
            if(option.length()<3)
            {
                cout<<"Now why are you trying to enter something too tiny (pun intended) ;-)";
                Y++;
            }
            if(option.length()>4)
            {
                cout<<"This isn't the time for buffer overflows yet";
                Y++;
            }
            if(option.length()==4&&!(option=="yes"||option=="Yes"))
            {
                cout<<"Tisk tisk, you tried to fool me by entering something the same size as yes, but not yes.\n";
                Y++;
            }
            if(option.length()==3&&!(option=="No")||option=="no")
            {
                cout<<"Tisk tisk, you tried to fool me by entering something the same size as no, but not no.\n";
                Y++;
            }
            cout<<"That was your "<<Y<<" consecutive error, don't try to hack the non=hacking part";
            if(Y=Z)
            {
                  cout<<"Congrats, you had no error this time ;-)\n";
                  Y=0;
            }
        }             
        if (Y==0)//If there is no errors
        {
            if(option=="Yes"||option=="yes")
            {
                char buffer[10];
                cout<<"Ok, now try to overflow me\n";
                cin>>buffer;
                cout<<buffer;
                cin.ignore();
                cin.get();
            }
            if(option=="No"||option=="no")
            {
                char buffer[10];
                cout<<"Ok, now try to overflow me\n";
                cin>>buffer;
                cout<<buffer;
                cin.ignore();
                cin.get();
                X=0;
            }
        }     
    }
    return 0;
}

Click on the Submit button only once, even if the page is really slow to load (as it's doing lately).

Code:

---

if(Y=Z)

---

Use == for comparison.

uuugh I want to tell it to display something if the text is as long as long but not "no"... maybe

Code:

---

if(option.length==2 && (option=!"No"||option=!"no"))

---

Edit:Got it, but longer than what I had hoped fr


Edit:Alright now I'm getting a F***ing "expected declaration before }" error message (on line 89(last line))
And i dont know what it wants

Code:
