Compiling errors with braces!

Expand Post »
As some of you would already know, I made a program which accepts login and password from users and shows "*" instead of actual password characters.
I know the program is grossly incorrect but I still tried to apply whatever I picked up using books and example programs.

*****DISCLAIMER- I am not an IT wizkid and calling me a beginner would be an extrapolated statement aswell. I am here to learn and discuss and not to be admonished at***************

Re: Compiling errors with braces!

WOW....

I have no idea what you are trying to do but you are WAY over your head.
1: Learn to use "tab"
2: password[c]= password[6] with no ; at the end? (Thatll problably solve 99% of the complying errors
3:
What the **** is this:
  1. {
  2. l=strcmp(&loginid[i], login);
  3. p=!strcmp(&pwd[i],password);
  4. for(i=o,i<=3,i++)
  5. }
  6.  
  7. {


Personally I think you come from another programming language that should either stick to it or reread from C manuals.

  15. void fnlogincheck()
  16. {
  17. char *pcloginid[3]={"user1","user2","user3"};

  30.  
  31.  
  32.  
  33. //l=strcmp(&loginid[i], login);

  35.  
  36. password[c]= password[6];
  37. printf("*");
  38. for(c=0;c<=6;c++)
  39.  
  40. {
  41. if( l=p)
  42.     printf("LOGIN ACCEPTED");
  43. else
  44.     printf("LOGIN DENIED");
  45.  
  46. exit;
  47. }
  48. }

But again, What the **** are you trying to do with this code???

ok...well..we were given this assignment to do a case senitive comaprison for teh password and a case insensitive comparison for the login..and show a "*" when we accept passwords form users..typical like gmail/orkut or for that matter daniweb...

thats what i did..and In my 17 years of studying, I have never ever undergone soft-skills training...so I guess that would account for the logic and syntax deprived code..!!

ofcourse there were examples of programs using logical operands like || but somehow I wanted to make it this way..

one more thins, since strcmp returns ansi c value and for everymatch, it returns 0, shouldnt l and p be equal to o..?

thanks

Re: Compiling errors with braces!

ahh!!

again, I feel there is a bug in Visual C++ 6.0 because my compiler seems hung-up on the braces!!!!

errors after compiling the above mentioned code-
practice1.c
- C:\Program Files\Microsoft Visual Studio\MyProjects\practice\practice1.c(46) : warning C4550: expression evaluates to a function which is missing an argument list
- C:\Program Files\Microsoft Visual Studio\MyProjects\practice\practice1.c(19) : warning C4101: 'i' : unreferenced local variable
- C:\Program Files\Microsoft Visual Studio\MyProjects\practice\practice1.c(57) : error C2084: function 'int __cdecl main(int ,char ** )' already has a body
- C:\Program Files\Microsoft Visual Studio\MyProjects\practice\practice1.c(64) : error C2084: function 'void __cdecl fnlogincheck()' already has a body
- C:\Program Files\Microsoft Visual Studio\MyProjects\practice\practice1.c(94) : warning C4550: expression evaluates to a function which is missing an argument list
Error executing cl.exe.

practice1.obj - 2 error(s), 3 warning(s)

Re: Compiling errors with braces!

How can you put p=o?

P is a integer. Do you even know what a integer is?

Even if I (or for that matter anyonw who has reached here) would not be a programmer, I would still know what an integer is!!


The question here is not whether we can allot value like zero to it, but to the best of my knowledge, on making a case insensitive/sensitive comparison for two strings, a differnce is returned if they are not found to be equal..(diffrnce of ansi c values)

Now for both the cases we are comparing strings with unequal lengths, login has a strlen of 5 characters and pwd has 6 characters..

how can we equate l to p?

the whole point of me making l =0 and p=0 was to make sure that l and p accept values which are already defined in the arrays!

still, I might be wrong, feel free to correct me.

Re: Compiling errors with braces!

and why cant 0 be allotted to an integer, initializing loops and allotting null to an integer always involves setting pointers on zero!
