我差不多完成了这个基本的骰子程序,但是很难找到我做错了什么。它应该为用户随机滚动2个骰子,并且他们可以选择保持它们滚动(K)或再次滚动(R)。我希望程序输出新的"随机"每次用户输入" R"当被问及他们是否想要再次滚动时,相同的数字仍在显示。
该程序的其余部分似乎运行良好 - 用户对抗计算机。当用户输入时,如何为roll1和roll2生成新数字" R"当被要求保留或重新滚动时?
#include <stdlib.h> /// need this for srand() -- for random numbers
#include <time.h> /// need this for time() -- time
#include <iostream> /// need this for cout<< and cin>>
using namespace std; /// need this for cout<< and cin>>
int main()
{
int iseed = (int)time(0);
srand(iseed);
cout << "Beat the computer! \n";
int roll1 = 1+rand()%6; /// make a random number for die # 1 for user
int roll2 = 1+rand()%6; /// make a random number for die # 2 for user
int UserRoll = roll1 + roll2; /// totals the sum of die 1 and die 2 for the user
char keep;
do
{
cout << "You rolled a " << roll1 << " and a " << roll2 << " for a total of: " << UserRoll << "\n";
cout << "\n";
do
{
cout << "Would you like to keep this total, or roll again? \n";
cout << "\n";
cout << "Enter \"K\" for keep and \"R\" for roll again: \n";
cin >> keep;
if (keep != 'K' && keep != 'R')
{
cout << "That is not a valid choice. Please choose Y to keep your total or N to roll again. " << endl;
cout << "\n";
}
} while(keep != 'K' && keep != 'R');
if (keep == 'R')
{
cout << "You chose R--let's roll again. \n";
}
else
{
cout << "Great! Your total is " << UserRoll << "\n";
}
} while (keep == 'R');
int roll3 = 1+rand()%6; /// make a random number for die # 1 for computer
int roll4 = 1+rand()%6; /// make a random number for die # 2 for computer
int ComputerRoll = roll3 + roll4; /// totals the sum of die 1 and die 2 for the computer
cout << "The computer rolled a " << roll3 << " and a " << roll4 << " for a total of: " << ComputerRoll << "\n";
cout << "\n";
if (ComputerRoll < UserRoll)
{
cout << "Congratulations! You won! \n";
}
if (ComputerRoll > UserRoll)
{
cout << "Sorry. You lose. \n";
}
if (ComputerRoll == UserRoll)
{
cout << "It's a tie. \n";
}
return 0;
}

SAMPLE RUNS:
------------
Beat the computer!
You rolled a 4 and a 6 for a total of: 10
Would you like to keep this total, or roll again?
Enter "K" for keep and "R" for roll again:
R
You chose R--let's roll again.
You rolled a 4 and a 6 for a total of: 10
Would you like to keep this total, or roll again?
Enter "K" for keep and "R" for roll again:
K
Great! Your total is 10
The computer rolled a 4 and a 6 for a total of: 10
It's a tie.

您只是滚动一次并再次使用该滚动的结果。如果用户再次按下R键。它应该再次滚动以更新新数字。为此,只需添加
void roll(){
roll1 = 1+rand()%6; /// make a random number for die # 1 for user
roll2 = 1+rand()%6; /// make a random number for die # 2 for user
UserRoll = roll1 + roll2; /// totals the sum of die 1 and die 2 for the user
}
请记住:roll1,roll2和UserRoll应在roll()函数
之前全局声明
在main()方法之前,当用户按下R时调用它 之后
cout << "Beat the computer! \n";
并从main方法中删除它。 这就是你需要做的所有事情
