How to randomize a number between 1 and 2

[LyUoGNh0]

Hi. I'm making a text adventure game and I was wondering how I could randomize a number. (BELOW IS A PART OF MY CODE)
Score is declared earlier in the code. I want right_Way to randomize a number between 1 or 2

// The Which way to go loop
while (game_Is_Running == 1) {
    // generate the right way
    right_Way = 2; // I want right_Way to equal 1 or 2

    cout << "You come across a two-way intersection. You can go left (1) or right (2)" << endl;
    cout << "Which way do you want to go?" << endl;	
    cin >> user_Input;
						
    if (user_Input == right_Way) {
        cout << "Congrates! You picked the right way!" << endl;
        score = score + 1;
        cout << "Your score is now " << score << endl;
	system("pause");
	system("cls");
    }else {
	cout << "You picked the wrong way..." << endl;
	score = score - 1;
	cout << "Your score is now " << score << endl;
	system("pause");
	system("cls");

    }		
}

In the beginning of your code, before the while loop type:

srand(time(0));

This will set the seed for your randomization.

Then you will need to include two things;

#include <time.h>
#include "windows.h" 

time.h This will allow you to get the time to your srand().
windows.h This will allow you to use srand() and rand().

Then you set right_Way to:

right_Way = (rand() % 2) + 1;

And there you have it, right_Way is now the value 1 or 2.

Hi. You should #include <ctime>
Then:
srand(time(0)) , so the number will be random every time.

int right_Way = rand() % 2 + 1;
if (right_Way == user_Input) { //If random number = input, your'e lucky (50% chance);
        cout << "Congrates! You picked the right way!" << endl;
        score = score + 1;
        ....
}

I think you want it to be like that.

2 errors, 1 warning. Error1: missing type specifier - int assumed. Note: C++ does not support default-int. Error2: 'srand' : redefinition; previous definition was 'function' Warning: 'initializing' : conversion from 'time.t' to 'int', possible lose of data

Line 8: You can't call a function in the global scope. Put it inside main().
