Question

Implement a program in C++ that does the following:

1. Reads the each of the words in a given input file (stackInput.txt)

2. Stores each of those words on to a Stack

3. After finishing the storage of all the data from the input file on to the stack, retrieve each of the

   values from the stack and write it to an output file and save the file with the filename (stackOutput.txt)

NOTE:

• Write comments

• Maintain proper indentation

• Create a STACK ADT using Object-Oriented Paradigm

• Use Modularity

Answer 1

code:-

#include <bits/stdc++.h>
using namespace std;
string push(string s);
std::vector<std::string> Stringarray; //decalring string array for storing words partially
std::vector<std::string> Stack; //stack for storing words
string push(string s){ //push function to insert into stack
   Stack.push_back(s); //pushing into the stack
}
int main()
{
fstream f;
string word, filename;
filename = "stackinput.txt"; //taking stackinput.txt
f.open(filename.c_str()); //opening file into fstream f
while (f >> word)
{  
   Stringarray.push_back(word); //storing into Stringrray
}
std::vector<std::string>::iterator i; //iterator for traversing
for ( i = Stringarray.begin() ; i < Stringarray.end() ; ++i )
{
push(*i); //push function for storing into stack
}
fstream outfile;
outfile.open("stackoutput.txt",ios::out); //opneing outputfile
int j;
   for (j = Stack.size() ; j> 0 ; j-- ) //reversing traversing
{
outfile<<Stack[j]; //append to new file(stackoutput.txt)
outfile<<" ";
}
return 0;
}

input File:- hai hello my name is ksr

output File :- ksr is name my hello hai
