c++ - 文件输出为十六进制？

Question

我正在制作一个程序，它会在评论中添加我的姓名、日期、文件名以及对它的功能的描述。它还会查找任何 int和 void函数，添加每个函数的功能描述。我已经完成了这些步骤!

我创建了一个 vector<string>它将整个文件读入自身。然后它搜索任何 void或 int vector 中的函数。如果它找到 int它叫string findParameters找到 int 的参数并在描述中列出它们。

示例:

/*THE DESCRIPTION THAT THE PROGRAM MADE IS BELLOW*/

/*Function: int nDigits
Description: 
     Description of the function
Parameters:
     long long number: Description
 Returns:
     returnVal: Description
*/

/*THE FUNCTION THE PROGRAM WAS LOOKING FOR IS BELLOW*/
int nDigits(long long number){


    int counter;
    for (counter = 0; number > 0; counter++){
        number = number / 10;

    }

    return counter;

}

问题

程序在不超过 160 行时运行良好，但当我输出时以及当我尝试在记事本中打开它时，超过它的任何内容都会将所有内容转换为十六进制，除了最后几个函数外，我的大部分代码都被删除了。

文件输出示例

0000 0000 0000 0000 0000 0000 0000 0000
0000 0000 0000 0000 0000 0000 0000 0000
0000 0000 0000 0000 0000 0000 0000 0000
0000 0000 0000 0000 0000 0000 0000 0000
0000 0000 0000 0000 0000 0000 0000 0000
0000 0020 2020 2020 200d 0a20 2020 2020
2020 2063 6f75 6e74 6572 2b2b 3b0d 0a20
2020 2020 2020 2066 616b 655f 6e75 6d62
6572 202f 3d20 3130 3b0d 0a20 2020 207d
0d0a 2020 2020 0d0a 2020 2020 0d0a 2020

当然有大约 400 行。

我不知道发生了什么，所以非常感谢任何帮助!我相信这可能限制了我在 vector 中放入多少行？

我的代码

查找参数函数

string findParameters(string line, string outputFileName, vector<string> &list_parameters){


    ofstream outFile;
    outFile.open(outputFileName, ios::out);
    int comma;
    string something;
    int length;
    int parstart;
    int parend;
    int last;
    if (outFile.is_open()) {

        if (line.find("(") != string::npos) {
            last = parstart = line.find("(",0) + 1;

            if (line.find(")", parstart + 1) != string::npos) {
                 parend = line.find(")", parstart + 1) + 1;



                    do {
                        comma = line.find(",", last+1);

                        if (comma == string::npos) {
                            length = parend - last;
                            something = line.substr(last, length-1);

                            list_parameters.push_back("\n     " + something);
                        }
                        else {
                            length = comma - last;
                            something = line.substr(last, length);

                            list_parameters.push_back("\n     " + something);
                            last = comma+1;
                        }
                    } while (comma != string::npos);




            }
        }
        outFile.close();
    }
    else {
        cout << "\nfile find parameters did not open";
    }

    return "";

}

此外，输出文件是程序正在命名的新文件，因此可以随意命名...这并不重要

我无法理解你的代码，但它看起来并没有对 vector 做太多事情，它只是存储它。如果我没记错的话，你可以像下面的代码一样让你的程序更短。

然而，要正确识别函数，您确实需要将线存储在 vector 中以检查它。

int main() 
{
    const char* note = "Etcetera Etcetera";

    ifstream in("in.cpp");
    ofstream out("out.cpp");

    string line;
    while (getline(in, line))
    {
        if (
                (
                    line.find('(') != string::npos && 
                    line.find(')') != string::npos
                ) 
                &&
                (
                    line.find("double") == 0 ||
                    line.find("int") == 0 ||
                    line.find("bool") == 0 ||
                    line.find("void") == 0
                )
            )
        {
            out << note << endl;
        }

        out << line << endl;
    }

    system("pause");
    return 0;
}
