例如T.txt文件中包含以下16进制数字(如下图排列一个数字占一整行)
0x47,
0x49,
0x46,
0x38,
0x39,
0x61,
0x88,
怎样将它转换成2进制并寸在另一个文件里或者覆盖原文件
如能告知不胜感谢

是以字符形式输出,读取和输出的格式都是一样的

问题已经解决,程序如下

#include <stdio.h>
#include <iostream.h>

int main()
{
unsigned int num;
unsigned int bit;
int start_print, i;

FILE *fp1 = fopen("g:\\work\\G_C401.OUT", "rt");
FILE *fp2 = fopen("g:\\B.txt", "wt");
if (!fp1 || !fp2)
{
if (fp1) fclose(fp1);
if (fp2) fclose(fp2);
return 1;
}

int ret = fscanf(fp1, "0x%x,\n", &num);
cout << ret << endl;
while( ret )
{
start_print = 0;

for (i=31; i>=0; i--)
{
bit = ( ((1 << i) & num ) != 0 );
if (!start_print && bit != 0)
start_print = 1;
if (!start_print && i==0)
start_print = 1;

if (start_print)
fprintf(fp2, "%d", bit);
}
fprintf(fp2, ",\n");

ret = fscanf(fp1, "0x%x,\n", &num);
// if(feof(fp1)>0)
// break;
}

fclose(fp1);
fclose(fp2);
return 0;
}
