Error Too Few Arguments To Function 'priv_gst_parse_yylex'
Date Jun 2011 Posts 2 error message: too few arguments for format Hi, everyone. I am a C programming learner. I wrote a little program but I get an error message when I try to compile it with gcc compiler. This is my little program: Code: #include int main() { int answer; printf ("Welcome to the English language quiz!\nPlease error too few arguments to function ‘cfg80211 ibss_joined’ answer the next question:\nWhat is the colour of the Lemon?\n1)Red\n2)Orange\n3)Yellow\nPlease type in the number of the right answer and press Enter:"); scanf ("%d, &answer"); if (answer == 3) { printf ("Congratulations! Your answer is right."); } else { printf ("Sorry. The right answer is 3)Yellow."); } return 0; } Error message: Code: liviu@liviu-pc ~/Desktop $ gcc welcome\ to\ c\ programming.c welcome to c programming.c: In function ‘main’: welcome to c programming.c:8:1: warning: too few arguments for format Can somebody explain to me what is wrong?

Is this condition guaranteed to be harmless, http://stackoverflow.com/questions/3578970/passing-too-many-arguments-to-printf or is there a potentially crash-inducing pitfall here, too? c printf share|improve this question asked Aug 26 '10 at 19:56 JSBÕ±Õ¸Õ£Õ¹ 28.8k1179132 3 Not an answer to your question, stacker's is correct, but for the crashes. gcc should give good warnings on that, so there is really no excuse for overlooking that one ;-) –Jens Gustedt Aug 26 '10 at 20:09 How could GCC give warnings for that? Consider that the format string doesn't necessarily have to be a constant string. It can be any char * –Nathan Fellman Aug 26 '10 at 20:24 1 GCC can give good warnings when it can know the format string at compile time. Since that represents a large swath of the rational use cases for printf and friends, those warnings are valuable and should be heeded. –RBerteig Aug 26 '10 at 21:00 gcc can also give warnings when the format string is not a string literal, if I remember correctly. This is to catch stupid things like printf(mystring);. –R.. Aug 26 '10 at 23:43 add a comment| 5 Answers 5 active oldest votes up vote 7 down vote accepted You probably know the prototype for the printf function as something like this int printf(const char *format, ...); A more complete version of that would actually be int __cdecl printf(const char *format, ...); The __cdecl defines the "calling convention" which, along with other things,

[PATCH] c/70883 - inconsistent error message for calls to __builtin_add_overflow with too few arguments From: Martin Sebor To: Gcc Patch List , Jakub Jelinek Date: Wed, 1 Jun 2016 15:09:10 -0600 Subject: [PATCH] c/70883 - inconsistent error message for calls to __builtin_add_overflow with too few arguments Authentication-results: sourceware.org; auth=none Jakub, As you requested in the discussion of my arithmetic overflow built-in patch, attached is the subset of the patch to make consistent with other such diagnostics the text of the error message issued for insufficient numbers of arguments in calls to built-in functions such as __builtin_add_overflow, __builtin_constant_p, and others.
