taskTesting.h:3:1: error: stray '\17' in program

这个错误通常是由于文件中存在不可见的非打印字符，例如二进制字符引起的。你可以尝试删除这个文件中的该行，并手动重新输入一遍，确保其中没有任何非打印字符。或者，你也可以使用文本编辑器的“显示非打印字符”功能来找到并删除这些字符。如果这个错误还是无法解决，你可以尝试使用其他文本编辑器打开该文件，或者重新下载源文件。

这个错误提示可能是因为你的代码中包含了一些非法字符。你可以尝试重新编写代码，并确保没有使用任何不必要的特殊字符或空格。此外，在 C++ 中，字符串必须使用双引号（"）而不是单引号（'）来表示。下面是一个示例代码，展示如何正确地声明和初始化字符串变量：

#include <iostream>
#include <string>

using namespace std;

int main() {
    string result = "Yes";
    cout << result << endl;

    result = "No";
    cout << result << endl;

    return 0;
}

这个程序将输出：

Yes
No

这个错误信息提示了一些编译错误。首先，代码中使用了非ASCII字符（如““”和“””），这会导致编译器无法识别。应该使用双引号（"）来表示字符串。其次，代码中使用了一些未定义的函数和变量，如`strlen`、`strcat`和`strcasecmp`函数，以及`pCharText`和`result`变量。应该添加相应的头文件，如`<cstring>`头文件中包含`strlen`和`strcat`函数，`<strings.h>`头文件中包含`strcasecmp`函数。同时，需要定义和初始化`pCharText`和`result`变量。最后，应该将比较字符串的函数修改为`std::string`类型的比较，而不是使用`strcasecmp`函数。修改后的代码如下：

#include <iostream>
#include <cstring>
#include <string>

std::string solution(std::string words, std::string msg){
    std::string result;
    int tStrLenW = words.length();
    int tStrLenM = msg.length();
    int tWordsFlag = 0;
    int tMsgFlag = 0;
    char* pCharText = new char[tStrLenM+1];
    memset(pCharText, 0, tStrLenM+1);
    while(tStrLenW > tWordsFlag && tStrLenM > tMsgFlag)
    {
        if(words[tWordsFlag] == msg[tMsgFlag])
        {
            pCharText[tMsgFlag] = msg[tMsgFlag];
            tMsgFlag++;
        }
        else
        {
            tWordsFlag++;
            tMsgFlag = 0;
        }
    }
    if(pCharText == msg)
        result = "Yes";
    else
        result = "No";
    delete[] pCharText;
    return result;
}

int main() {
    std::string words;
    std::string msg;
    getline(std::cin, words);
    getline(std::cin, msg);
    std::string result = solution(words, msg);
    std::cout<<result<<std::endl;
    return 0;
}

注意，这里我将比较字符串的方法修改为了`pCharText == msg`，因为在C++中，可以直接使用`==`运算符来比较两个`std::string`类型的字符串是否相等。
