Question

estion 3 1. Suppose the file mystery.txt contains the text below: The whole thing starts about twelve, fourteen or seventeen. #include <iostream> #include <fstream> #include <string> using namespace std; int main() { string word; int i = 0; ifstream read("mystery.txt"); while(!read.eof()) { read>>word; if(i < word.length()) cout<<word[i]; i++; } cout<< endl; 3 seventeen Thirteen fourteen twelve A Moving to the next question prevents changes to this answer. 29

Answer 1

correct option is Thirteen

ifstream read("mystery.txt"); this reads the mystery.txt file

   while(!read.eof()) // loop continues until the end of the text
   {
       read>>word; //string word stores the each word that is read one after another
       if(i<word.length())
       {
           cout<<word[i];
       }
       i++;
   }

The text is  The whole thing starts about twelve,fourteen or seventeen

i=0

word = The

word.length = 3

so i<word.length .....condition is true so cout<<word[i]

word[0]=T so T will be printed

i is incremented

i=1

word =  whole

word.length = 5

so i<word.length .....condition is true so cout<<word[i]

word[1]=h so h will be printed

i is incremented

i=2

word = thing

word.length = 5

so i<word.length .....condition is true so cout<<word[i]

word[2]=i so i will be printed

i is incremented

i=3

word = starts

word.length = 6

so i<word.length .....condition is true so cout<<word[i]

word[3]=r so r will be printed

i is incremented

i=4

word = about

word.length = 5

so i<word.length .....condition is true so cout<<word[i]

word[4]=t so t will be printed

i is incremented

i=5

word =  twelve

word.length = 6

so i<word.length .....condition is true so cout<<word[i]

word[5]=e  so e will be printed

i is incremented

i=6

word = fourteen

word.length = 8

so i<word.length .....condition is true so cout<<word[i]

word[6]=e so e will be printed

i is incremented

i=7

word = or

word.length = 2

so i>word.length .....condition is not true so nothing will be printed

i is incremented

i=8

word = seventeen

word.length = 9

so i<word.length .....condition is true so cout<<word[i]

word[8]=n so n will be printed

now we have reached end of the text so the loop breaks

When we combine the letters printed in each iteration we get

Thirteen

So option 2 is correct
