当写入以文本模式打开的文件而不是以二进制模式打开的文件时，会发生什么转换？特别是在MS Visual C中.
unsigned char buffer[256];
for (int i = 0; i < 256; i++) buffer[i]=i;
int size = 1;
int count = 256;
二进制模式:
FILE *fp_binary = fopen(filename, "wb");
fwrite(buffer, size, count, fp_binary);
与文本模式相比:
FILE *fp_text = fopen(filename, "wt");
fwrite(buffer, size, count, fp_text);
