嗨,大家好我在这个地方有错误:C++ strcpy_s智能感知错误
strcpy_s(msgToGraphics, game.board_now());
的错误是:
IntelliSense: no instance of overloaded function "strcpy_s" matches the argument list argument types are: (char [1024], std::string)
这里是game.board_now FUNC:
string Board::board_now()
{
return _board;
}
这里是其余的代码,我尝试使用strncpy_s:
#include "Pipe.h"
#include "Board.h"
#include <iostream>
#include <thread>
using namespace std;
void main()
{
srand(time_t(NULL));
Pipe p;
bool isConnect = p.connect();
string ans;
while (!isConnect) {
cout << "cant connect to graphics" << endl;
cout << "Do you try to connect again or exit? (0-try again, 1-exit)" << endl;
cin >> ans;
if (ans == "0") {
cout << "trying connect again.." << endl;
Sleep(5000);
isConnect = p.connect();
}
else {
p.close();
return;
}
}
char msgToGraphics[1024];
// msgToGraphics should contain the board string accord the protocol
// YOUR CODE
Board game;
//strcpy_s(msgToGraphics, game.board_now()); // just example...
p.sendMessageToGraphics("rnbkqbnrpppppppp################################PPPPPPPPRBNKQNBR0"); // send the board string
// get message from graphics
string msgFromGraphics = p.getMessageFromGraphics();
while (msgFromGraphics != "quit") {
game.change_board(msgFromGraphics);
game.change_board_sq(msgFromGraphics);
strcpy_s(msgToGraphics, game.board_now()); // msgToGraphics should contain the result of the operation
// return result to graphics
p.sendMessageToGraphics(msgToGraphics);
// get message from graphics
msgFromGraphics = p.getMessageFromGraphics();
}
p.close();
}
该代码基本上是一个国际象棋程序,我尝试在我做出的更改后接收棋盘,并且我不知道如何在strcpy_s中格式化他以便将其放入数组并将其发送回给定的exe。 感谢所有尝试帮助的人!
为什么不'msgToGraphics'一个'的std :: string'呢?你可以避免很多麻烦,避免使用简单的'char'数组,在这种情况下,你可以通过operator =赋值给另一个字符串,如'msgToGraphics = game.board_now();'。 –
,因为它必须是数组,因为这是接口接收的信息 – SimpleNigal
这不是一个好的理由。您可以使用string :: c_str()将字符指针传递给您的API。 –
