Need help in c++, please and thank you

Use the Concept of vector and string to do the following question

1)      Write a program that creates a vector of string called “Vec”. Vector “Vec” grows and shrinks as the user processes the transactions from a data file called “Transaction.txt”. The transaction file can only include three types of commands: Add, Remove, and Print. With “Add” command, you get two more information, the information you need to put into the vector and the position the information should be inserted. With “Remove”, you get one more information that indicates which element (index) should be deleted. Print command means the content of the vector should be printed on the screen. For example, you may have the following information in your file:

Add       Hello       4

Remove           5

Print

The first line indicates that the word “Hello” should be located in the forth index which means Vec [4]. Of course you should check if this insert is possible. This insert is possible if the position you are attempting to insert the element is not beyond the size of the vector. The second line means Vec [5] should be removed. Again this operation should only be allowed if the index is not beyond the current size of the vector. Test your program with the following Transaction file:

Add   Student   0

Add   Kid       0

Add   Final       1

Add   Grow       1

Add   Note       2

Print

Add   Rich       5

Remove       1

Remove       7

Add   Mind       2

Remove       3

Print

Explanation / Answer

Sorry for using too much #define ..Here is in simplest form :)

#include<bits/stdc++.h>

using namespace std;

int main(){
ifstream in;
in.open("data.txt");
string s;
vector<string>V;
int i,j;
while (!in.eof())
{
getline(in,s);
string temp;
vector<string> str;
stringstream line(s);
while (line >> temp)str.push_back(temp);
int len=V.size();
if (str[0]=="Insert")
{
i = atoi(str[2].c_str());
if (i <= len)
V.insert(V.begin()+i,str[1]);
}
else if (str[0]=="Delete")
{
i = atoi(str[1].c_str());
if (i <len)V.erase(V.begin()+i);
}
else
{
puts("VECTOR IS");
for (j = 0; j <len; j++)cout<<V[j]<<" ";
puts(" ");
}
}
return 0;
}
