[英]C++ 'Word Jumble'
我有一个小问题。 我试图用计分系统制作“ Word Jumble”游戏。 但是有时候,当计算机猜出一个单词时,它会说:这个单词是: 这里空白 。 那里应该有一个混乱的词。 当我尝试任何单词时,它只会减去1.#INF点。
码:
#include<iostream>
#include<string>
#include<stdlib.h>
#include<time.h>
using namespace std;
const int size=10;
string Words[size] = {
"consecutive",
"alternative",
"consequently",
"jumbled",
"computer",
"charger",
"food",//I'm hungry
"library",
"strawberry",
"carrier"
};
string Hints[size] = {
"Following continuously.",
"Something available as another opportunity.",
"As a result.",
"This word is rather jumbled, isn't it ;)",
"The enitiy you are reading this off of",
"My phone battery is running low",
"I'm hungry, I need some _",
"Where can I go get a book?",
"It's red, and not a berry."
"Either carries stuff, or is what your data company is called."
};
void main()
{
string word,hint;
double points=0;
bool correct=false,playAgain=true;
cout << "Welcome to Word Jumble!\n";
cout << "The objective of this game is to guess the jumbled word, correctly.\n";
cout << "Say 'quit' to quit, or 'hint' for a hint.\n";
while (playAgain==true)
{
correct = false;
int guesses = 0;
srand(static_cast<unsigned int>(time(0)));
int num = rand() % size + 1;
word = Words[num];
hint = Hints[num];
string jumble = word;
int length = jumble.size();
for (int i = 0; i < length*2; ++i)
{
int index1 = (rand() % length);
int index2 = (rand() % length);
char temp = jumble[index1];
jumble[index1] = jumble[index2];
jumble[index2] = temp;
}
cout << "The word is: " << jumble << endl;
double tempPoints=0;
while (correct==false)
{
string theGuess;
cout << "Guess the word: ";
cin >> theGuess;
guesses++;
while (!cin)
{
cin.sync();
cin.clear();
cout << "Ivalid entry, try again: ";
cin >> theGuess;
}
if (theGuess == word)
{
cout << "Correct! You guessed the word in only " << guesses << " tries!\n";
tempPoints += jumble.size()*1.5;
tempPoints -= (guesses - 1) / 4.0;
points += tempPoints;
cout << "You have been awarded " << tempPoints << " points this round for a total of " << points << "!\n";
correct = true;
cout << "Would you like to play again? (y or n): ";
char tempYN;
cin >> tempYN;
while (!cin || tempYN != 'y' && tempYN != 'n')
{
cin.sync();
cin.clear();
cout << "Invalid entry.\nWould you like to play again? (y or n): ";
cin >> tempYN;
}
if (tempYN == 'y')
{
playAgain = true;
}
else
{
playAgain = false;
}
}
else if (theGuess == "hint")
{
tempPoints -= (1.0 / (jumble.size())) * 40;
cout << "Hint: " << hint << endl;
correct = false;
playAgain = true;
}
else if (theGuess == "quit")
{
correct = true;
playAgain = false;
}
else
{
double sub = (1.0 / (jumble.size())) * 20;
cout << "Incorrect word, deducting "<<sub<<" points\n";
tempPoints -= sub;
playAgain = true;
correct = false;
}
};
};
cout << "Goodbye\n";
}
在该行中:
int num = rand() % size + 1;
您说的是选择一个介于0到9之间的随机数,然后加1。
如果随机数是9,则+ 1将使它成为10。这意味着您正在尝试访问数组Words
and Hints
处索引10的值。由于数组被索引为0,并且其大小为10,这意味着您只有元素在0-9。
您也永远不会获得数组中的第一个字符串。
