    Sure, and I wil give HINTS to solutions, but part of learning to program is to learn how to "think" in terms of "how to solve problems using a computer". And that's not always that easy.

    Giving you the right solution directly is not going to help you.

    Good start. I would probably start the loop with 0 - that's the traditional way to do loops.

    Also, you just loop around asking, not checking if the answer is right (and breaking the loop when this happens).

    Edit: And, if you expect the user to actually input "02.10.69", you may want to have a string longer than 6 chars - consider that:
    there are 6 positions for the date itself, then two dots, and all strings also need a "ending zero". So you are at least 3 short.

    you cannot simply put

    ans=02.10.69

    first because of the == vs = and second because 02.10.69 is a string "02.10.69"
    if you want to compare string:

    #include <string.h>
    ....

    if(strcmp(ans,"02.10.69")==0) break;

    It also helps if you post the EXACT error message from the compiler. It can be hard to spot some subtle errors without the information of what the compiler says.

    here is the new coding...no errors..no warnings...:
    Code:
    #include <string.h>
    #include <stdio.h>
    void main()
    {
    	int count;
    	char ans[9];
    
    	printf("\n Welcome to the QuiZ Competition....R u READY????");
    
    
    	for (count=1; count<3; ++count)
    
    	{
    		printf("\n What is the date of birth of Gandhi?");
    		scanf("&#37;s",&ans);
    		if(strcmp(ans,"02.10.69")==0) break;
    
    		else printf("\n The answer u stupid is 02.10.69");
    	}
    
    	{
    		printf("\n Fabulous worK..Ur Great...");
    	}
    	}

    I know it is upsetting... but trying to rewrite the same program with "while loop" could be useful...

    That looks about right. What's not working is that you don't say "bravo" when the user gets it right - and perhaps you want to say "try again" when the user gets it wrong.
    And you don't really need the braces around the answer - but if you want to say "stupid" then you probably should only print it when the answer is wrong.

    You can solve most of the "do this" or "don't do this" by adding a variable to say "correct" or "not correct", e.g "correcAnswer = 0" to begin with, and if you get a correct answer, set "correctAnswer = 1". Then when the loop ends [for whatever cause] you check the variable "correctAnswer" to see if it was correct or not.

    doesn't your compiler give you a warning about return type of 'main' ? It should be int...

    To add on to what matsp advised: change void main() to int main(), then include a return 0; statement at the end of main() if you are not compiling with respect to the C99 standard.

    Also, I believe you should actually use:
    Code:
    scanf("&#37;s", ans);
    C + C++ Compiler: MinGW port of GCC
    Version Control System: Bazaar

    You could write a function to ask a question and compare it to a correct answer. And you could also either call this function from another function that sums up the number of right answers, or call a function that updates a score for the person when the answer is right. Or something like that.

    the "score" of the user is the variable "count" (maybe +1 if loop start from zero.) what do you mean for store the corect answerrs in a particular function ?
