一串十六進位以每兩位形式轉換成字串

例如 

121209055822010053轉換後為 

cc953a161035

#include <stdio.h>#include <string.h>int main(){char hex[200];char s[100];strcpy(hex,"98e1e97b3294cd43260aa8766dd21b9e354f5926d34f9b5fa510e84937316992a740a46b41d3e4fbe4ec285b2bc992db5f12d3cc0388e726b00f80fadd73f77846b40e8c75bb90739a484ec60a2c38422411f418e5ae075ac16194a3b1a60bd3");int L=strlen(hex), i, v;for (i=0;i<L/2;i++) {sscanf(hex+i*2,"%2X",&v);s[i]=(char)(v&0xFFu);}s[i]=0;printf("%s\n",s);L=strlen(s);for (i=0;i<L;i++) sprintf(hex+2*i,"%02x",(unsigned char)s[i]);hex[2*i+2]=0;printf("%s\n",hex);}

以上代碼輸出：
