Need help with a roll dice program
I need to create a roll dice program that allows the user to both input a desired sum and the number of times they want the dice to be rolled. I can get the first part but I cant get it the part where you enter a number of rolls.
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int num, rollDice(int num);
int main()
{
cout << "Enter the desired sum of the two die" << endl;
cin >> num;
cout<< "The number of tries to get the desired sum = " << num << rollDice(num) << endl;
return 0;
}
int rollDice(int num)
{
int die1;
int die2;
int sum;
int rollCount = 0;
srand(time(0));
do
{
die1 = rand() % 6 + 1;
die2 = rand() % 6 + 1;
sum = die1 + die2;
rollCount++;
}
while (sum != num);
return rollCount;
}
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int num, rollDice(int num);
int main()
{
cout << "Enter the desired sum of the two die" << endl;
cin >> num;
cout<< "The number of tries to get the desired sum = " << num << rollDice(num) << endl;
return 0;
}
int rollDice(int num)
{
int die1;
int die2;
int sum;
int rollCount = 0;
srand(time(0));
do
{
die1 = rand() % 6 + 1;
die2 = rand() % 6 + 1;
sum = die1 + die2;
rollCount++;
}
while (sum != num);
return rollCount;
}

Then you will need a variable to store each of these values, such as
|
|
For each of these, use
cout to prompt the user and cin to get the value.At the moment, you only have one
cin, you need two.
I have this now, but it doesn't change anything
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int num, rollDice(int num);
int main()
{
int num, sum;
cout << "Enter the desired sum of the two die" << endl;
cin >> sum;
cout << "Enter the number rolls you want" << endl;
cin >> num;
cout<< "The number of tries to get the desired sum = " << num << rollDice(num) << endl;
return 0;
}
int rollDice(int num)
{
int die1;
int die2;
int sum;
int rollCount = 0;
srand(time(0));
do
{
die1 = rand() % 6 + 1;
die2 = rand() % 6 + 1;
sum = die1 + die2;
rollCount++;
}
while (sum != num);
return rollCount;
}
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int num, rollDice(int num);
int main()
{
int num, sum;
cout << "Enter the desired sum of the two die" << endl;
cin >> sum;
cout << "Enter the number rolls you want" << endl;
cin >> num;
cout<< "The number of tries to get the desired sum = " << num << rollDice(num) << endl;
return 0;
}
int rollDice(int num)
{
int die1;
int die2;
int sum;
int rollCount = 0;
srand(time(0));
do
{
die1 = rand() % 6 + 1;
die2 = rand() % 6 + 1;
sum = die1 + die2;
rollCount++;
}
while (sum != num);
return rollCount;
}
Allow the user to enter the desired sum of the numbers to be rolled as well as allow the user to call the rollDice function as many times as desired
| allow the user to call the rollDice function as many times as desired |
Here I'm not sure what is supposed to happen. The program calls the rollDice() function just once. Are you saying it should be called more than once?
I'm not sure, I just copied what the textbook says for the problem, it's worded really confusingly
I was wondering whether the loop where the dice were rolled should be executed a fixed number of times (like a for-loop) or maybe set an upper limit on how many repetitions. Not sure what to suggest right now.
I think I need to give the user an option to play again somehow, but i'm not really sure how to go about it
