Why is srand() not being stored in my variable?

This beginner's program I am trying to make is basically a program where a truly random number is generated and the "player" has to guess the number. The computer will respond "too high" or "too low" until the player guesses the right number.

I got this program idea from some website, and thought I should roll with it. This is my second program- my first being a simple I/O program.

Here is my code:

// BracketingSearch.cpp

#include "stdafx.h"
#include <iostream>
#include <cstdlib>
#include <string>
#include <ctime>
#include <istream>
#include <fstream>
using namespace std;

int main() 
{

int x = srand(time(0));
cout << x << endl;
for (int x = 1; x <= 10; x++) {
    cout << 1 + (rand() % 100) << endl;
}
string stall;
getline(cin, stall);
}

Side notes: I don't think I need that many headers; I am still getting use to the c++ libraries. Please critique my code as much as possible. I am eager to learn programming! The string stall is just to make my console application pause for input, so I can see the results.

Thank you for everyone who can help! -Mike
