Question

我仍在为我的程序而苦苦挣扎，应该用符号打印字符编译器说：

char参数与char *
类型不兼容

这是我的代码：

char characters[12] = {"ABCDEFGHIJ\0"};
char numbers[12] = {"0123456789\0"};

for (int vertical = 2; vertical<12; vertical++) {
    for (int horizontal = 1; horizontal<2; horizontal++) {
        text2(horizontal, vertical, numbers[horizontal]);
        color2(horizontal, vertical, BLUE);         
    }       
}

for (int abc = 170; abc < 180; abc++) {
    color(abc, BLUE);
    text(abc, characters[abc]);
}

实际上每次打印只能打印一个字符。这里有两个功能

void color2(int i, int j, int f) {
    sprintf_s(nachricht, ">># %d %d 0x%x\n", i, j, f);
    sendMessage( nachricht );
void text2(int i, int j, char* f) {
    sprintf_s(nachricht, ">>#T %d %d %s\n", i, j, f);
    sendMessage( nachricht );
}

color2颜色字段和text2显示字段上的字符这是函数sendMessage的代码，它包含在两个提到的函数中

int sendMessage(char *sendbuf ) {
    WSADATA wsaData;
    SOCKET ConnectSocket = INVALID_SOCKET;
    struct addrinfo *result = NULL,
        *ptr = NULL,
        hints;
    int iResult;
    int recvbuflen = DEFAULT_BUFLEN;
    char recvbuf[DEFAULT_BUFLEN];

    // Initialize Winsock
    iResult = WSAStartup(MAKEWORD(2,2), &wsaData);
    if (iResult != 0) {
        printf("WSAStartup failed with error: %d\n", iResult);
        return 1;
    }

    ZeroMemory( &hints, sizeof(hints) );
    hints.ai_family = AF_UNSPEC;
    hints.ai_socktype = SOCK_STREAM;
    hints.ai_protocol = IPPROTO_TCP;

    // Resolve the server address and port
    iResult = getaddrinfo("localhost", DEFAULT_PORT, &hints, &result);
    if ( iResult != 0 ) {
        printf("getaddrinfo failed with error: %d\n", iResult);
        WSACleanup();
        return 1;
    }

    // Attempt to connect to an address until one succeeds
    for(ptr=result; ptr != NULL ;ptr=ptr->ai_next) {

        // Create a SOCKET for connecting to server
        ConnectSocket = socket(ptr->ai_family, ptr->ai_socktype, 
            ptr->ai_protocol);
        if (ConnectSocket == INVALID_SOCKET) {
            printf("socket failed with error: %ld\n", WSAGetLastError());
            WSACleanup();
            return 1;
        }

        // Connect to server.
        iResult = connect( ConnectSocket, ptr->ai_addr, (int)ptr->ai_addrlen);
        if (iResult == SOCKET_ERROR) {
            closesocket(ConnectSocket);
            ConnectSocket = INVALID_SOCKET;
            continue;
        }
        if( verbose ) printf("socket connected\n");
        break;
    }

    freeaddrinfo(result);

    if (ConnectSocket == INVALID_SOCKET) {
        terminate("Unable to connect to server!\n");
    }

    // Send an initial buffer
    iResult = send( ConnectSocket, sendbuf, (int)strlen(sendbuf), 0 );
    if (iResult == SOCKET_ERROR) {
        printf("send failed with error: %d\n", WSAGetLastError());
        closesocket(ConnectSocket);
        WSACleanup();
        return 1;
    }

    if( verbose ) printf("Bytes Sent: %ld\n", iResult);

    // shutdown the connection since no more data will be sent
    iResult = shutdown(ConnectSocket, SD_SEND);
    if (iResult == SOCKET_ERROR) {
        printf("shutdown failed with error: %d\n", WSAGetLastError());
        closesocket(ConnectSocket);
        WSACleanup();
        return 1;
    }

    answer[0] = '\0';
    // Receive until the peer closes the connection
    do {


        iResult = recv(ConnectSocket, recvbuf, recvbuflen, 0);
        if ( iResult > 0 ) {
            recvbuf[iResult] = '\0';
            if( verbose ) printf("Bytes received: %d %s\n", iResult, recvbuf);
            strcat_s( answer, recvbuf );
            //printf(">>>%s<<<\n", answer );
        } else if ( iResult == 0 ) {
            if( verbose ) printf("Connection closed\n");
        } else
            printf("recv failed with error: %d\n", WSAGetLastError());

    } while( iResult > 0 );

    // cleanup
    closesocket(ConnectSocket);
    WSACleanup();

    return 0;
}

您需要取消引用指针。可能是在你调用的函数之一中，可能是在text2（）或text（）中。如果不了解更多关于功能的规格，就无法告诉你更多信息。
