[RESOLVED] There is some thing wrong with my code

Hi im using Visual Studio.net 2003 C++ and i just bought this book Called
Hacker Disassembling Uncouvered and the first project is to type a simple code that makes a login type thing and i typed it word for word from the book and i get all these errors here is the code i typed in and the ERRORS.

Code:

---

 
// macthing the pass char wwith the corrwect car.
// basicly making a login screen if pass is ok then go if pass is wrong the display message,

#include <stdio.h>
#include <string.h>

#define PASSWORD_SIZE 100
#define PASSWORD  "myGODpassword\n"
// cr above is need
//so as not to cut it off
// the user enterd CR

int_main()
{
//the counter for authentication failurs
        int count=0;
//buffer size for the user-entered password
        char buff[PASSWORD_SIZE],

//main authentication loop
for(;;)
{
        //prompt the user for pass
        //and read it
        printf("enter password: ");
        fgets(&buff[0],PASSWORD_SIZE,stdin);

        //matching the entered pass with the referenced one
        if (strcmp(&buff[0],PASSWORD))
                //"scolding if the pass is wrong
                printf("WRONG PASSWORD\n");
        //otherwise if pass matches then go on
        //getting out of loop
        else break;

        //incrementing the counter of authentication failures
        //and terminating the program if 3 attempts have been used
        if (++count>3) return -1
}
//once we're here, the user has entered the right pass
printf("Password OK\n");
}

Dont mind my sort hand.

here are the errors
-Projects\simple\simple.cpp(21): error C2059: syntax error : 'for'

-Projects\simple\simple.cpp(21): error C2143: syntax error : missing ';' before ')'

-Projects\simple\simple.cpp(22): error C2143: syntax error : missing ';' before '{'

-Projects\simple\simple.cpp(34): error C2043: illegal break

-Projects\simple\simple.cpp(39): error C2143: syntax error : missing ';' before '}'

I hope you guys or girls can help. :wave:

missing semicolon before for and after return -1

ok i put the semicolon befor "for" an after -1 now i get this error

Projects\simple\simple.cpp(21): error C2059: syntax error : ';'

missing semicolon after -1.

Code:

---

if (++count>3) return -1;

Here is the code now after what sunnypalsingh told me to do and i still get 1 error

// macthing the pass char wwith the corrwect car.
// basicly making a login screen if pass is ok then go if pass is wrong the display message,

#include <stdio.h>
#include <string.h>

#define PASSWORD_SIZE 100
#define PASSWORD "myGODpassword\n"
// cr above is need
//so as not to cut it off
// the user enterd CR

int_main()
{
//the counter for authentication failurs
int count=0;
//buffer size for the user-entered password
char buff[PASSWORD_SIZE],

//main authentication loop
;for(;;)
{
//prompt the user for pass
//and read it
printf("enter password: ");
fgets(&buff[0],PASSWORD_SIZE,stdin);

//matching the entered pass with the referenced one
if (strcmp(&buff[0],PASSWORD))
//"scolding if the pass is wrong
printf("WRONG PASSWORD\n");
//otherwise if pass matches then go on
//getting out of loop
else break;

//incrementing the counter of authentication failures
//and terminating the program if 3 attempts have been used
if (++count>3) return -1;
}
//once we're here, the user has entered the right pass
printf("Password OK\n");
}

here is the error-

-Projects\simple\simple.cpp(21): error C2059: syntax error : ';'

When I click on the error it goes to ";for(;;)" I dont know what to do plzzz Help?

Im sry i didnt put it in that box thing

oh...you want spoon feeding....before for I meant this

Code:

---

char buff[PASSWORD_SIZE];

---

But now i get these ERRORS

-simple fatal error LNK1120: 1 unresolved externals

-simple error LNK2019: unresolved external symbol _main referenced in function _mainCRTStartup

-projects\simple\simple.cpp(42): warning C4715: 'int_main' : not all control paths return a value

please try this, but it is not tested. the highlighted part is what i have either changed or added.

Code:

---

// macthing the pass char wwith the corrwect car.
// basicly making a login screen if pass is ok then go if pass is wrong the display message,

#include <stdio.h>
#include <string.h>

#define PASSWORD_SIZE 100
#define PASSWORD  "myGODpassword\n"
// cr above is need
//so as not to cut it off
// the user enterd CR

int main()  //why using underscore here??
{
//the counter for authentication failurs
        int count=0;
//buffer size for the user-entered password
        char buff[PASSWORD_SIZE];

//main authentication loop
for(;;)
{
        //prompt the user for pass
        //and read it
        printf("enter password: ");
        fgets(&buff[0],PASSWORD_SIZE,stdin);

        //matching the entered pass with the referenced one
        if (strcmp(&buff[0],PASSWORD) != 0) //though logically you were right
                                                          //but never take chances
                //"scolding if the pass is wrong
                printf("WRONG PASSWORD\n");
        //otherwise if pass matches then go on
        //getting out of loop
        else break;

        //incrementing the counter of authentication failures
        //and terminating the program if 3 attempts have been used
        if (++count>3) return -1
}
//once we're here, the user has entered the right pass
printf("Password OK\n");
return 0;  //returning the value for int main
}
