Rand() function

[bamskates218]

I'm trying to make a simple console game using Microsoft visual c++ 2010. It is a guessing game in which it creates a random number and you try to guess the number. There are two options, 1 to 10, or 1 to 100. The problem is it keeps generating a new random number every time i guess. I need the number to stay the same throughout the game. Does anyone know what the problem is?

Here is my code:

#include <iostream>
#include <time.h>

using namespace std;

void game1();
void game2();

void main() {
	cout << "Guess the number" << endl;
	cout << "----------------" << endl;
	cout << "Please select an option" << endl;
	cout << "1. 1 to 10" << endl;
	cout << "2. 1 to 100" << endl;
	int selection;
	cin >> selection;
	if (selection == 1) {
		game1();
	}
	if (selection == 2) {
		game2();
	}
}

void game1() {
	system("cls");
	cout << "Guess the number (1 to 10):" << endl;
	for (int times = 1;;times++) {
		char answer;
		int guess;
		int number;
		srand(time(0));
		number = int(rand() &#37; 10 + 1); 
		cin >> guess;
		if (guess == number)
		{
			system("cls");
			cout << "You win!" << endl;
			cout << "It took you " << times << " times to guess." << endl;
			cout << "Would you like to play again? (y/n)" << endl;
			cin >> answer;
			if (answer = 'y') {
				game1();
			}
			if (answer = 'n') {
				main();
			}
			system("pause");
		}
		else
			if (guess > number) {
				cout << "The number is less than " << guess << ". Guess the number (1 to 10):" << endl;
			}
		else
			if (guess < number) {
				cout << "The number is more than " << guess << ". Guess the number (1 to 10):" << endl;
			}

	}
}

void game2() {
	system("cls");
	cout << "Guess the number (1 to 100):" << endl;
	for (int times = 1;;times++) {
		char answer;
		int guess;
		int number;
		srand(time(0));
		number = int(rand() % 100 + 1); 
		cin >> guess;
		if (guess == number)
		{
			system("cls");
			cout << "You win!" << endl;
			cout << "It took you " << times << " times to guess." << endl;
			cout << "Would you like to play again? (y/n)" << endl;
			cin >> answer;
			if (answer = 'y') {
				game2();
			}
			if (answer = 'n') {
				main();
			}
			system("pause");
		}
		else
			if (guess > number) {
				cout << "The number is less than " << guess << ". Guess the number (1 to 100):" << endl;
			}
		else
			if (guess < number) {
				cout << "The number is more than " << guess << ". Guess the number (1 to 100):" << endl;
			}

	}
