indentation error

This is a discussion on indentation error within the C Programming forums, part of the General Programming Boards category; Code: #include<stdio.h> #include<stdlib.h> #include<math.h> void main(void) { //Declaration double v_a,v_b,v_c,discriminant,root_1,root_2,sq_d; //Input printf("Enter a, b, c : "); scanf("%lf %lf %lf",&v_a,&v_b,&v_c); ...

    indentation error

    Code:
    #include<stdio.h>
    #include<stdlib.h>
    #include<math.h>
    
    void main(void)
    {
    	
    	//Declaration
    	double v_a,v_b,v_c,discriminant,root_1,root_2,sq_d;
    	
    	
    	//Input
    	printf("Enter a, b, c : ");
    	scanf("%lf %lf %lf",&v_a,&v_b,&v_c);
    	
    	
    	//Calculation
    	discriminant = (pow(v_b,2))-(4*v_a*v_c); 
    	sq_d = sqrt(discriminant);
    	root_1 = (-v_b+sq_d)/(2*v_a);
       	root_2 = (-v_b-sq_d)/(2*v_a);   
    	
    	
    	if (discriminant >= 0)
    	{
    		printf("\na=%f  b=%f  c=%f\n",v_a,v_b,v_c);
    		printf("\nThe roots are %.2f and %.2f\n",root_1,root_2);
    	}
    	else
    	{
    		printf("a=%f  b=%f  c=%f\nd = %f\n",v_a,v_b,v_c,discriminant);
    		printf("\nThe roots are complex.\n");
    	}
    	
    	exit(0);
    }   //End main
    The above program works fine but there is a INDENTATION ERROR when marking with online marking system......

    If it ain't a compiler or run-time error, you ain't likely to get much help here!

    It is not that old programmers are any smarter or code better, it is just that they have made the same stupid mistake so many times that it is second nature to fix it.

    Really? Might want to watch for a user input error causing a divide by 0.
    Code:
    scanf("%lf %lf %lf",&v_a,&v_b,&v_c);  //suppose I enter 0 first
    //v_a = 0
    <snip>
    root_1 = (-v_b+sq_d)/(2*v_a); //numerator/(2*0) = no good

    Cboard has an online marking system? I have to wonder what exactly you're talking about.
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    > void main(void)
    Indentation is the least of your problems.
    main returns int - read the FAQ

    > INDENTATION ERROR
    Sure - you go read the spec for the problem and find out what precise sequence of spaces, newlines and tabs will generate the "right answer"
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
