Question

该程序输入用户给出的单词并将其翻译成猪拉丁语。我已经使所有工作几乎完美地工作，但是遇到了两个错误。首先是翻译以辅音开头的单词“ count”时，输出为“ ounttcay”而不是“ ountcay”。第二个错误是，对于三个字母词，例如“ egg”或“ not”，输出为“ egg_ \ 377ay”或“ ottn \ 377ay”。有没有简单的方法来删除重复的字符并摆脱那些数字？

注意-不幸的是，必须使用Cstring完成

Answer 1

您没有终止newArr，并且输入字符串的最后一个索引是arrLength - 1。

int convertToPigLatin(char arr[50]) {
        // Make sure newArr is properly terminated.
        char newArr[50] = {0};

        // [...]
        } else { //else if the given input starts with a consonant
            for (int r = 1; r < arrLength; r++) {
                newArr[r-1] = newArr[r];
            }
            // Do this outside the loop.
            newArr[arrLength-1] = lastChar;
            // No need for strcat here.
            cout << "Your word in piglatin is " << newArr << "ay" << endl;
        }
    }
    return 0;
}

Answer 2

您需要在newArr的末尾添加'\ 0'，因为strlen不会对其进行计数，因此您无需复制它。 strcat用'ay \ 0'替换'\ 0'，但是您没有'\ 0'。

for (int r = 1; r < arrLength; r++) {
     newArr[r-1] = newArr[r];
     newArr[arrLength] = lastChar;
}
newArr[arrLength+1] = '\0';
cout << "Your word in piglatin is " << strcat(newArr, "ay") << endl;
