比如说字符 i j k l m其实就是十进制的 105 106 107 108 109 也是十六进制的0x69 0x6A 0x6B 0x6C 0x6D，它们在计算机内部的存储方式都是二进制存储的。我想，你所位的转换，是只在屏幕上显示的转换。
比如说：
char a = 'm'
printf("Display by decimalization: %d",a);
printf("Display by Hex: %x",a);
printf("Display by character: %c",a);
是指转换成字符串吗？如下：
//---------------------------------------------------------------------------
#include <stdio.h>
int main(int argc, char* argv[])
{
char str[80];
int hex=0x3d;
sprintf(str,"%X",hex); /*将hex变量的值以16进制格式输出到字符数组str*/
puts(str); /*输出str字符数组*/
return 0;
}
//---------------------------------------------------------------------------
