C++ Quiz Problem

Hi

Im new to this forum, I just signed up

I have a problem with my code. I am trying to make a quiz, it was working fine yesterday. I tried to debug it today and i got 29 errors!

I dont understand how that happened, I have looked at the output and I just dont see whats wrong with it. Any help would be greatly appreciated, and yes I a noob

Code is below:

Code:

#include "stdafx.h"
#include <stdio.h>
#include <iostream>

int main();
}
char a;
printf("GENERAL QUIZ\n");
printf("\n");
printf("Who is the chairman of Microsoft Corp?\n");
printf("1 Bill Gates\n");
printf("2 Steve Jobs\n");
printf("3 Jake Taylor\n");
a=getchar();
if (a=='1') printf("Correct\n"); else printf("Wrong\n");
while (a!='z');
  {
  a=getchar();
{

EDIT: You'll have to explain things carefully as I can get easily confused

There is an excess semicolon after main(), and another after while(). Your code block brackets don't match. You always begin a block with {, and end with }. If you start, you must end it, therefore there will always be an even number of brackets.
1st bracket: backwards
2nd: ok
3rd: backwards
4th: awol

Also, you are missing a return 0; statement at the end of main().

You should learn how to indent your code properly as well for readability purposes, especially when you're debugging.

Ok thanks. I'll try what you (rossipoo) suggested later. I'll let you know how I get on. Thanks again

For future reference, it helps if you post the errors that you receive.

Ok, Im on one error now. I still dont understand it though.

: fatal error C1075: end of file found before the left brace '{' at 'c:\users\------ ----------documents\visual studio 2008\projects\test1.1\test1.1\test1.1.cpp(6)' was matched

Post your updated code.

Sorry. I have to get used to this

Code:

#include "stdafx.h"
#include <stdio.h>
#include <iostream>

int main()
{
char a;
printf("GENERAL QUIZ\n");
printf("\n");
printf("Who is the chairman of Microsoft Corp?\n");
printf("1 Bill Gates\n");
printf("2 Steve Jobs\n");
printf("3 Jake Taylor\n");
a=getchar();
if (a=='1') printf("Correct\n"); else printf("Wrong\n");
while (a!='z')
  {
  a=getchar();
}

You get the error because your braces don't match, like pointed out earlier.

Code:

#include "stdafx.h"
#include <stdio.h>
#include <iostream>

int main()
{
char a;
printf("GENERAL QUIZ\n");
printf("\n");
printf("Who is the chairman of Microsoft Corp?\n");
printf("1 Bill Gates\n");
printf("2 Steve Jobs\n");
printf("3 Jake Taylor\n");
a=getchar();
if (a=='1') printf("Correct\n"); else printf("Wrong\n");
while (a!='z')
  {
  a=getchar();
  }
}

Also, look into indentation.

WOW. It works and I feel so stupid, haha

Thanks guys, it really means alot. I hope I'll stay here and learn alot from you guys.
Thanks again

No problemo!

By the way, do you realise that your print functions are in C, not C++?

Actaully no I didn't.

My teacher showed me then, he mainly used C and not C++.

How do I change these to C++ Print Functions, and whats the difference between the C version and the C++ version?

Thanks

Well I'm not a C programmer, so I can't tell you the difference between the two, but I can tell you how to translate between the two.

To print text to the console, use std::cout followed by the output operator <<

To acquire user input and store it into a variable, use std::cin followed by the input operator >>

I'll demonstrate:

Code:

#include <iostream>

int main()
{
    char a;
    std::cout << "GENERAL QUIZ\n";
    std::cout << "\n";
    std::cout << "Who is the chairman of Microsoft Corp?\n";
    std::cout << "1 Bill Gates\n";
    std::cout << "2 Steve Jobs\n";
    std::cout << "3 Jake Taylor\n";
    std::cin >> a;
    if (a == '1')
    {
        std::cout << "Correct\n";
    }
    else
    {
        std::cout << "Wrong\n";
    }
    while (a != 'z')
    {
        std::cin >> a;
    }
}

As you can see, I've removed outdated header files that aren't needed for the program, and replaced your C functions with C++ functions. The braces highlighted are my programming style although, feel free to use your own. :P

Ah i see the difference.

Thank you
