#include <iostream>
#include <conio.h>
using namespace std;

int words(char sentence[]){
int numberOfWords=0;
int wordFlag=0;
char* pointer=sentence;
while ((*pointer)!=NULL) {
if(((*pointer)!=' ')&&((*pointer)!='
')&&((*pointer)!=' ')&&(!wordFlag)) {
numberOfWords++;wordFlag=1; }
if(!(((*pointer)!=' ')&&((*pointer)!='
')&&((*pointer)!=' '))) {
wordFlag=0; }
pointer++; }
return numberOfWords;
}

int main ()
{
char sentence[] = "abcdefd";
cout << words(sentence);
system("pause");
return 0;
