16进制到字符串:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
int a[6] = {0x12,0x34,0x56,0x78,0xab,0xcd};
char *str = (char*)malloc(32);
memset(str,0,32);
int i = 0;
for(i = 0; i < 6;i++)
{
sprintf(str,"%s%x",str,a[i]);
}
for(i = 0; i < strlen(str);i++)
{
printf("%c ",str[i]);
}
printf("\n%s\n",str);
return 0;
}
