Question

Problem 2: The following dictionary word and its meaning is given. Create a struct data structure such that when the client types the word, the meaning of that word is displayed.

Word: foo; Meaning: A file

Word: fooo; Meaning: A long file

Word: foooo; Meaning: A long long file

Word: fooooo; Meaning: A long long long file

Word: foooooo; Meaning: A long long long long file

Word: fooooooo; Meaning: A long long long long long file

Write the algorithm in a .doc file and C++ code of the problem

Answer 1

Algorithm:

Step 1: Start
Step 2: Define a structure dictionary
Step 3: Declare variables dictionary, word, flag, temp, file
Step 4: Initialising the variable
           flag <- 0
           open file <- dictionary.txt
Step 5: Read word from user.
Step 6: Repeat the steps until !file.eof()
6.1 Read the first word into temp
            second word into dictionary.word
            third word into temp
            rest line into dictionary.meaning

6.2 if dictionary.word = word
        flag = 1
        break

Step 7: If flag=1
Display dictionary.meaning
else
Display meaning not found
Step 8: Stop

Code:

#include<iostream>
#include<fstream>
#include<string>

using namespace std;

// Struct data type dictionary
struct dictionary
{
string word;
string meaning;
};

int main()
{
ifstream file("dictionary.txt"); // opening the file that contains the word and meanings
int flag=0;
string word,temp;
dictionary d1;

if(!file.is_open()) // Checking if the file is open
{
cout<<"File doesnt exist!!";
exit(0);
}

cout<<"Enter the word you want to search : "; // getting the word from the user
cin>>word;

while(!file.eof()) // reading till the end of file
{
file>>temp;
file>>d1.word;
d1.word.pop_back();
file>>temp;
getline(file,d1.meaning);
if(d1.word==word) // checking if the word in the file and user entered is matching
{
flag=1;
break;
}
}

if(flag==1) // if its matching
cout<<endl<<"The meaning if the word "<<d1.word<<" is "<<d1.meaning<<endl;
else // if it doesn't match
cout<<endl<<"The meaning of the word could not be found!!"<<endl;

file.close(); // closing the file

}

Output:
