Dice Game

[brendanr425]

Hello! I'm trying to write a program that will generate a value between one and six. (Simulating a dice roll) Each of these values will output a different message and add said value to the variable "num". The user will be prompted to press 'y' to loop the program again. However, once num reaches a value => 30, the program will end. The only trouble I'm having is that it generates the same value/message every time you loop the program. The initial value/message is randomized every time you run the program, but the loop just repeats the same value/message until you reach a number => 30. I want the dice roll to be randomized every time you loop the program instead of every time you run the program.

#include<iostream>
#include<ctime>
#include<cstdlib>
#include<string>

using namespace std;

int main()
{
    
    int number = 6;
    int result = 0;
    int num = 0;
    char choice = '\0';
    
    srand(time(NULL));
    
    result = rand() % number + 1;
    do
    {

    switch(result)
    {
        case 1:
            num = num + 1;
            cout << "You rolled a one!" << endl;
            cout << "Num = " << num << endl;
            break;
        case 2:
            num = num + 2;
            cout << "You rolled a two!" << endl;
            cout << "Num = " << num << endl;
            break;
        case 3:
            num = num + 3;
            cout << "You rolled a three!" << endl;
            cout << "Num = " << num << endl;
            break;
        case 4:
            num = num + 4;
            cout << "You rolled a four!" << endl;
            cout << "Num = " << num << endl;
            break;
        case 5:
            num = num + 5;
            cout << "You rolled a five!" << endl;
            cout << "Num = " << num << endl;
            break;
        case 6:
            num = num + 6;
            cout << "You rolled a six!" << endl;
            cout << "Num = " << num << endl;
            break;
    }
        
        if (num < 30)
        {
        cout << "Do you want to roll again? " << endl;
        cin >> choice;
        }
        else
        {
            cout << endl;
            cout << "You win!" << endl;
            cout << endl;
        }

    }
    while (choice == 'y' && num < 30);
    
    

    return 0;
}

Help would be greatly appreciated. Thank you!

Move line 18 to line 21 (inside the loop).
You're calling rand() only once (before you enter the loop).
