Write a program that reads a string using gets and then counts and displays the number of words.

#include <stdio.h>
#include <string.h>
#include <conio.h>
#define MAX_SIZE 100

main()
{
	char sentence[MAX_SIZE];
	int length, nb_words, i;

	printf("Enter the sentence : ");
	gets(sentence);

	nb_words = 1;
	length = strlen(sentence);

	/* for each encountred space, increment the number of words */
	for (i = 0; i < length; i++) {
		if (sentence[i] == ' ') {
			nb_words++;
		}
	}
	
	printf("There's %d word%s in your sentence sentence\n", nb_words, (nb_words==1?"":"s"));
	getch();
}
