Word, Lines, Characters Counting In C Programming

This programs counts the lines, words, and characters. Every time the program encounters the first characters of a word, it counts one more word.
The variable ‘state’ records whether the program is currently in a word or not.

#include 
#define IN 1
#define OUT 0
main()
{
	int c, nl, nw, nc, state;
	clrscr();
	state = OUT;
	nl	=nw	=nc	=0;
	while((c=getchar()) !=EOF){
		/** count the character **/
		++nc;
		/** count the line **/
		if(c ==' ' || c == '\n' || c =='\t')
			state = OUT;
		else if(state == OUT){
			state = IN;
			/** count the word **/
			++nw;
		}	
	}
	printf("Number Of Line		=%d\n",nl);
	printf("Number Of Word	 	=%d\n",nw);
	printf("Number Of Character =%d\n",nc);
	getch();
}
