我的代码在不同的平台上给出了不同的输出

Question

首先这是代码。

#include <iostream>
#include <string.h>

using namespace std;

int main() {

    char word[20];
    char blank[20];
    char guess[1];
    char *pch;
    int life=6;

    cout<<"Enter your word : ";
    cin>>word;

    for(unsigned int i=0;i<strlen(word);i++){

        blank[i]='_';

    }

    cout<<blank<<endl;

    while(blank != word && life >= 0){

        if(strcmp(word,blank) == 0){

            cout<<"Congratulations you found the word. :)";
            break;
        }


        if(life == 0)break;

        cout<<"Your guess :";
        cin>>guess[0];

        pch=strchr(word,int(guess[0]));

        if(pch == NULL){

        cout<<"Your guess is wrong try again."<<endl;
        cout<<life<<endl;

        }

        else if(pch != NULL){

            while (pch!=NULL){
                blank[pch-word]=guess[0];
                pch=strchr(pch+1,int(guess[0]));
            }

            cout<<blank<<endl;
            cout<<life<<endl;

            life++;

        }

        --life;

    }

    if(life == 0)cout<<"Sadly you couldn't find the word. :(";

    return 0;
}

所以我想写一个刽子手代码。我设法在 Eclipse 中处理这个非常糟糕的编写代码。它在某种程度上完成了工作，但是当尝试将它实现到代码块时，程序的这一部分似乎无法正常工作。

    for(unsigned int i=0;i<strlen(word);i++){

        blank[i]='_';

    }

    cout<<blank<<endl;

Codeblocks 给我这样奇怪的输出：

Enter your word : ankara
______B
Your guess ::

或者这个：

Enter your word : adana
_____rB
Your guess :

有谁知道为什么代码块给我不同的输出？顺便说一下，请原谅我的英语不好。

使用 C++ 字符串代替 cstrings

#include <iostream>
#include <string>

using namespace std;

int main() {
    std::string word;
    char guess;
    char *pch;
    int life=6;

    cout<<"Enter your word : ";
    cin>>word;
    std::string blank(word.size(), '_');

    cout<<blank<<endl;

    while(blank != word && can >= 0){

        if(word == blan){

            cout<<"Congratulations you found the word. :)";
            break;
        }


        if(life == 0)break;

        cout<<"Your guess :";
        cin>>guess;

        pch=strchr(word.c_str(),int(guess));

        if(pch == NULL){

        cout<<"Your guess is wrong try again."<<endl;
        cout<<life<<endl;

        }

        else if(pch != NULL){

            while (pch!=NULL){
                blank[pch-word.c_str()]=guess;
                pch=strchr(pch+1,int(guess));
            }

            cout<<blank<<endl;
            cout<<life<<endl;

            life++;
        }
        --life;
    }
    if(can == 0)cout<<"Sadly you couldn't find the word. :(";

    return 0;
}
