How to make an array of strings stored in a vector

I am trying something like this: 

#include <iostream>
#include <vector>
#include <cstring>

using namespace std;

int main()
{

    string inputStr;
    vector <string> strVector;
    cin.getline(inputStr,200);
    int i=0;
    while (inputStr!=NULL){ //unless all data is read.
        strVector[i]=getline(inputStr," ");
        i++;
    }//while.

    for (int j=0; j<strVector.size(); j++){
        cout<< strVector[j];
        cout<<endl;
    }
} //main.

Any one who can help. I am trying to store my input string in vector string and then I can push_back my ith string.

Here is nother way:

#include <iostream>
#include <string>
#include <vector>


using namespace std;



int main(int argc, char *argv[])
{
    vector<string> strVec;
    string str;
    cout<<"Enter # to quit \n\n";
    int i=0;


    while (str!="#")
    {  
        cout<<"Input text No. "<<i+1 <<" here > ";
        cin>>str ;
        strVec.push_back(str);


        i++;
    } 

    cout<<"\nStored text\n----------\n";
    for (int j=0; j<strVec.size()-1; j++)    cout<<j+1<<"  "<< strVec[j]<<"\n";


    cout<<"\n\n";

    return(0);
}

Much of your code involving inputString is invalid. There is no getline member of istream that takes a std::string, so this is invalid:

cin.getline(inputStr,200);

What you want there instead is the global getline:

getline(cin, inputStr);

Second, there is no global getline which reads directly from a std::string, so this is invalid:

strVector[i]=getline(inputStr," ");

What you want to use there is an istringstream. Altogether, your code might look something like this:

std::getline(std::cin, inputStr);
std::istringstream iss(inputStr);
std::string word;
// read from the istringstream until failure
while (std::getline(iss,word,' '))
    strVector.push_back(word);

If you want to delimit on whitespace(including tabs) then you can use operator>> instead of getline.

I think you are looking for the push_back method of the std::vector template
