我对C ++还是很陌生，我刚刚完成了有关类的学习。我不知道为什么我不断收到此错误C4244（检查标题）。 我正在使用Visual Studio 2017 反馈将不胜感激。

//我的程序要求用户输入一个句子     `

#include <iostream>
using namespace std
Const short MAX = 132;

class information
{
char sentence[MAX];
short gcount;
public:
    unsigned short CharCount;
    void InputData();
    void showresult();
};
Int main()
{
    Information data;
    data.InputData();
    data.showresult();
    return 0;
}

void information::InputData()//member function to enter info
{
    cin.ignore(10,'\n');
    cout << "Enter your sentence " << endl;
    cout << endl;
    cin.getline(sentence,sizeof(sentence));
    CharCount = cin.gcount(); // this is the problem

}

void information::showresult() //show number of characters
{
    cout << " Characters in the sentence:: " << CharCount  << endl; 
    system(“Pause”);
}
