16进制转换成字符串

[wain_]

例如：
char str[] = {0xab,0xbc,0xcd,0xde};
转换： char *buf = "abbccdde";

char buf[10];
char bin[50] = {0x,ab,0xbc,0xcd};
char str[100];
len = strlen(bin);
for (i = 0; i < len; i++) {
       sprintf(buf,"%s",bin[i]);
        strcat(str,buf);
}

上面这种方法哪里不适合的吗？

char buf[10]; char bin[50] = {0xab,0xab,0xbc,0xcd}; char str[100] = {0}; int len = strlen(bin); int i; for (i = 0; i < len; i++) { sprintf(buf,"%.2x",(unsigned char)bin[i]); strcat(str,buf); } return 0;

引用 1 楼 piaobotudou 的回复:

char buf[10]; char bin[50] = {0xab,0xab,0xbc,0xcd}; char str[100] = {0}; int len = strlen(bin); int i; for (i = 0; i < len; i++) { sprintf(buf,"%.2x",(unsigned char)bin[i]); strcat(str,buf); } return 0;

多谢指点

char bin[50] = {0xab,0xbc,0xcd};
char str[100];
for (i = 0; i < 3; i++) {
    sprintf(str+i*2,"%02X",(unsigned char)bin[i]);
}

1楼代码是错的。
