Input at most 4 words

[jekaterina]

I would like to cin at most 4 words but I couldn't figure out a suitable algorithm.

I have tried the below one but obviously it doesn't work.
And I don't know either string or char array I should use.

  	int i(0),no(0);
	string input[4];
	char in[100];
	cout<<"Please input the query string: ";
	while(cin>>in[i]){
		if(no>4||in[i]=='.')break;
		if(in[i]==' ') no++;
		i++;}

Use std::string instead of char[]
You are making the code a bit too complicated. I wrote an example for you here:

#include <iostream>
#include <sstream>
#include <string>

int main()
{
    std::stringstream in("word1 w2 w3 w4 w5 w6.");
    std::string words[4];
    for(int i = 0; i < 4; i++) {
        in >> words[i];
        std::cout << "words[" << i << "]: " << words[i] << std::endl;
    }
    return 0;
}
