Question: Detect Repeat Word Program

[InclinedToFall]

Hey all,

I'm new here and excited to share ideas and learn from one another.

I'm going through Stroustrup's book "Programming." I'm doing this on my own, so I am going to need all the help I can get. I appreciate your patience ahead of time. Maybe someday I'll be able to help people just like me on this forum in later days.

I'm compiling with Dev-C++. Also, I am using a specific header file as you can see in the #include.

Anyway, here is the code:

#include "std_lib_facilities.h"

int main()
{
	string previous = " ";	// previous word initialized to "not a word"
	string current;			// current word
	while (cin>>current){	// read stream of words
		if (previous == current);	// check if word is same as the last
			cout<<"repeated word: "<<current<<'\n';
		previous = current;
	}
}

Instead of returning repeated words, all words are being returned after the string. Frustrating.

Thanks for the help,
Incline

The if statement has a ';' that should not be there. With indentation to make it more clear:

		if (previous == current) {
			;	// check if word is same as the last
		}
		cout<<"repeated word: "<<current<<'\n';
		previous = current;

Firedraco,

Something so simple, but I was so blind to it without your help. Thanks!
