TO COUNT THE NUMBER OF WORDS IN A GIVEN STRING

This is the program to count number of words in the entered sentence.

Logic: The logic behind this program is checking if the character in the sentence is a 'blank' and with the conditions that the next is not a blank character, or current character position is not equal to length of the sentence. If so, variable 'words' is incremented by one as one new word found.

#include<stdio.h>
#include<conio.h>
void main()
{
        char str[50];
        int words = 0, len = 0, i;
        clrscr();
        printf("\n\n\t ENTER A STRING...: ");
        gets(str);
        while(str[len]!='\0')
              len++;
        len--;
        for(i=0;i<=len;i++)
        {
              if ( ( str[i] == ' ' && str[i+1] != ' ' ) || i == len )
                      words++;
        }
        printf("\n\t NUMBER OF WORDS IN THE ABOVE SENTENCE IS...: %d", words);
        getch();
}
