我正在制作一个简单的多维数据集根猜测游戏,其中会生成随机数并显示其多维数据集,然后用户输入多维数据集根的含义。这是我的程序:
int main()
try {
int max, min;
max = 99; min = 1; // only cubes of 1-99 are displayed
// display the title
cout << "\n\t\t\t\tCube Root Game" << endl;
cout << "\t\t\t\t=============\n" << endl;
srand(time(0)); // seed for random number generator
// display 10 numbers for the user to guess the cube root
for (int i = 0; i < 10; i++) {
int answer; // answer inputted by the user
int temp = rand() % (max - min) + min; // random number
int t3 = temp * temp * temp; // cube of the random number
cout << "\tEnter the cube root for " << t3 << " : ";
cin >> answer;
if (answer == t3) {
cout << "\tCorrect answer!\n" << endl;
}
else {
cout << "\tIncorrect answer\n" << endl;
}
}
keep_window_open("q");
}
catch (runtime_error& e) {
cerr << "Error: " << e.what() << endl;
keep_window_open("q");
return 1;
}
catch(...) {
cerr << "Unexpected error.\n";
}
问题是,当我正确输入多维数据集根时,它总是说这是不正确的,但是if比较对我来说似乎还可以,所以我不知道这是怎么回事。
最佳答案
if (answer == t3)
您不是这个意思吗?
if (answer == temp)
(您希望用户猜测根,而不是立方体,对吧?):-)
