C++实现十六进制表示字符串

using namespace std;

char* strToHexArray(const char*input)
{

strcat(out,"char out[]={");
for(int i=0;i<strlen(input);i++)
{
char str[64]={0};
sprintf(str, "0x%x,", input[i]); //将100转为16进制表示的字符串。
//cout<<str<<endl;
strcat(out,str);
}
int len=strlen(out);
out[len-1]=0;

//strncpy(out,out,len-1);
return out;
