Question

我正在尝试读取文本文件并将其内容输出到结构中。（我正在尝试先输出内容，而不是立即使用结构。）

我尝试读取文件，但是即使它们相同并且文件存在，它似乎也无法识别名称。

文本文件（“ settings.txt”）

vida 3
vel_bola 1
vel_barreira 1
tamanho 15
quant_tijolos 30
tipo_tijolo 1
vel_brinde 1
tipo_brinde 1
tempo_brinde 60
prob_normal 70
prob_resist 20
prob_magico 10
sound 1

到目前为止我的代码

int _tmain(int argc, LPTSTR argv[]) {

#ifdef UNICODE
    _setmode(_fileno(stdin), _O_WTEXT);
    _setmode(_fileno(stdout), _O_WTEXT);
#endif

    //jogo j;

    HANDLE hFile;
    byte buffer[BUFFERSIZE] = { 0 };
    DWORD nIn = 0;

    LPCWSTR fName = TEXT("settings.txt");

    hFile = CreateFile(fName, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

    if (hFile == INVALID_HANDLE_VALUE) {
        _tprintf(TEXT("Error opening the file %s!\n\n"), fName);
    }else
        _tprintf(TEXT("File %s Open!\n\n"), fName);

    if (ReadFile(hFile, buffer, BUFFERSIZE - 2, &nIn, NULL) == FALSE) {
        _tprintf(TEXT("It wasn't possible to read the file %s\n\n"), fName);
        CloseHandle(hFile);
        return -1;
    }

    if (nIn > 0 && nIn <= BUFFERSIZE - 2) {
        buffer[nIn] = TEXT('\0');
    }

    _tprintf(TEXT("%s", buffer));   

    return 0;

}

编辑：使用结构

typedef struct Jogo {

    unsigned vidas;
    unsigned vel_bola;
    unsigned vel_barreira;
    unsigned tamanho_barreira;
    unsigned quant_tijolos;
    unsigned tipo_tijolo;
    unsigned vel_brinde;
    unsigned tipo_brinde;
    unsigned tempo_brinde;
    unsigned prob_normal;
    unsigned prob_resist;
    unsigned probm_magico;
    BOOL sound;

}jogo;

我希望内容像文本文件一样在屏幕上打印出来，但是它给我的结果是空的（来自调试）。

更新：现在，它读取文件并将所有内容放入缓冲区，但仍不会打印到屏幕上。

更新结束

UPDATE2：它可以按预期的方式工作，现在只需将其放入结构即可。

UPDATE2 END

Answer 1

TEXT宏可能不理解逗号

TEXT("%s", buffer)

所以我会用

_tprintf(TEXT("%s"), buffer);

或者只是

_tprintf("%s", buffer);

两者都将_tprintf的参数分开。

除了使用Windows File Api读取文件外，还可以使用流方法：

#include <windows.h>
#include <fstream>  

#include <iostream>  
#include <tchar.h>
using namespace std;
#define BUFFERSIZE 1024
typedef struct Jogo {

    unsigned vidas;
    unsigned vel_bola;
    unsigned vel_barreira;
    unsigned tamanho_barreira;
    unsigned quant_tijolos;
    unsigned tipo_tijolo;
    unsigned vel_brinde;
    unsigned tipo_brinde;
    unsigned tempo_brinde;
    unsigned prob_normal;
    unsigned prob_resist;
    unsigned probm_magico;
    BOOL sound;//BOOL is defined as int;

}jogo;
int _tmain(int argc, LPTSTR argv[]) {

#ifdef UNICODE
    _setmode(_fileno(stdin), _O_WTEXT);
    _setmode(_fileno(stdout), _O_WTEXT);
#endif

    jogo j;
    unsigned int arr[13] = { 0 };
    char memmber[BUFFERSIZE] = { 0 };
    ifstream OpenFile("settings.txt");
    for (int i = 0; i < 13; i++)
    {
        OpenFile >> member;
        OpenFile >> arr[i];
        _tprintf(TEXT("%s %d\n"), member,arr[i]);//Also need to ensure the order in .txt file is the same as the struct members.
    }
    memcpy(&j, arr,sizeof(arr));//Since the memory of struct members is the same as arry, so we can convert it with memory copy.

    return 0;

}

更新：

使用C库函数sscanf（从文件中获取缓冲区后）：

...
_tprintf(TEXT("%s"), buffer);
char temp[20] = { 0 };
sscanf_s(buffer,"%s %d %s %d %s %d %s %d %s %d %s %d %s %d %s %d %s %d %s %d %s %d %s %d %s %d",temp,&j.vidas,temp,&j.vel_bola, temp, &j.vel_barreira, temp, &j.tamanho_barreira, temp, &j.quant_tijolos, temp, &j.tipo_tijolo, temp, &j.vel_brinde, temp, &j.tipo_brinde, temp, &j.tempo_brinde, temp, &j.prob_normal, temp, &j.prob_resist, temp, &j.probm_magico, temp, &j.sound);
