#include <Windows.h> 
#include <stdio.h> 

int count = 0; 
FILE* pFile = 0; 
long Size = 0; 

void *memfrob(void * s, size_t n) 
{ 
    char *p = (char *) s; 

    while (n-- > 0) 
        *p++ ^= 42; 
    return s; 
} 

int main() 
{ 
    fopen_s(&pFile, "***", "r+"); 
    fseek(pFile, 0, SEEK_END); 
    Size = ftell(pFile); 
    char *buffer = (char*)malloc(Size); 
    memset(buffer, 0, Size); 
    fread(buffer, Size, 1, pFile); 
    fclose(pFile); 
    memfrob(buffer, Size); 
    fopen_s(&pFile, "***", "w+"); 
    fwrite(buffer, Size, 1, pFile); 
    fclose(pFile); 
}

嗨,fread没有读取从文件到缓冲区的任何内容,我无法弄清楚原因.有人能给我一个暗示或推动正确的方向吗？

我收到以下错误:

在这段代码:

map<string, var> variables;
streamsize sum = 0;

if (sum) {
    variables["$RESULT"] = sum;  // Error 1
    return true;
}

和

class var
