c++ - 为什么算法在第一个条件后结束？

Question

我正在设计一种用作游戏的猜数算法。

谁能提出为什么算法在第一个条件后结束？

#include <iostream>

using namespace std;

int main()
{

int num = 5;
int guess;

cout << "Guess a number \n";
cin >> guess;


if (guess==num)
{
    cout << "You guessed the correct number \n";
}
else if (guess < num)
{
    cout << "Your guess is lower than the number \n";
    cout << "Guess again \n";
    cin >> guess;
}
else
{
    cout << "Your guess is higher than the number \n";
    cout << "Guess again \n";
    cin >> guess;
}


return 0;

如果您希望重复该算法，则需要某种循环。

例如

#include <iostream>

using namespace std;

int main()
{
    int num = 5;
    int guess;

    cout << "Guess a number \n";

    do
    {
        cin >> guess;

        if ( guess == num )
        {
            cout << "You guessed the correct number \n";
        }
        else if ( guess < num )
        {
            cout << "Your guess is lower than the number \n";
            cout << "Guess again \n";
        }
        else
        {
            cout << "Your guess is higher than the number \n";
            cout << "Guess again \n";
        }

    } while ( guess != num );

    return 0;
}
