Thread: error:unterminated character constant

What is unterminated character constant error?

here is the code that gives me that error:

Code:

#include<stdio.h>
#include<conio.h>
#include<math.h>

main()

{
	
	
	float a,b,c,x;
	printf("Use this to work out the length of the hypotenuse on a right angled triangle.\n");
	printf("Please enter a:");
	scanf("%f",&a);
	printf("\nPlease enter b:);
	scanf("%f",&b);
	
	// a*a+b*b=c*c;
	
	x=a*a+b*b;
	c=sqrt(x);
	
	printf("\nThe triangle's hypotenuse has a length of %f ",c);
	
	getch();
	
	return 0;
}

and the part compiler tells me where the error occurs:

Code:

printf("\nThe triangle's hypotenuse has a length of %f ",c);

Look at line 14 where you ask for input b. This should stand out if you're using an editor that does syntax highlighting. If you're not, then you should start using such an editor. Many editors can do this, and it's great for spotting such mistakes.

Thanks,anduril462.Which compiler do you suggest me?I am using C-free.

Thanks for the advice,Salem.

If you mean which editor do I suggest: C-Free is fine. It's an IDE with an editor that does syntax highlighting (at least in the newest version). I've never used it before, so you may need to change some options to make it work or upgrade if your version doesn't support it.

If you actually want a compiler recommendation to use with C-free, I would suggest MinGW, which is a free Windows port of GCC. Many people here use it and like it.

C-free does highligthning but it doesn't show where the error is,properly.I'll try that MinGw.Thx.
