c语言如何把数组转换成字符串

1、编写转换程序:void hex_to_str(char *hex, int hex_len, char *str){ int i, pos=0; for(i=0; i<hex_len; i++) { sprintf(str+pos, "%02x", hex[i]); pos +=2; }}

2、测试:char hex_data[] ={0x11, 0x12,0x13,0x14,0x15,0x16,0x17,0x18,0x19};char str_data[128];hex_to_str(hex_data, 9, str_data);printf("%s", str_data);
