Consider this data sequence: "fish bird reptile reptile bird bird bird mammal fish". there is a consecutive repetition of length 3 (the three consecutive birds) and a consecutive repetition of length 2 (the two reptiles). there are also several singletons of length 1 (a singleton fish, a singleton bird, a singleton mammal, and another singleton fish).write some code that uses a loop to read in a sequence of words, terminated by the "". the code assigns to t the number of consecutive repetitions that were read. (for example, in the above data sequence that value would be 2.) assume that t has already been declared but not initialized . assume that there will be at least one word before the terminating "".

The code is given below. Follow the question and the code definitions for better understanding.

Explanation:

#include<iostream>

#include<string>

using namespace std;

int main(){

string pastWord="";

string currentWord,nextWord;

int n,t;

int singleton=0;

int consecutive=0;

cout<<"Enter words. ('' to exit):\n";

cin>>nextWord;

do{

currentWord=nextWord;

cin>>nextWord;

if ( (currentWord!=pastWord)&&(currentWord!=nextWord) )

singleton++;

else if((currentWord==pastWord)&&(currentWord!=nextWord))

consecutive++;

pastWord=currentWord;

}while(nextWord!="");

n=singleton;

t=consecutive;

cout<<"There were "<<n<<" singletons and "<<t<<" consecutive repetitions.";

cin.get();

return 0;

}

the answer is d.
