here are the basics

char buffer[128];
// read in buffer
// now buffer contains some string

int len = strlen(buffer);
char hex[4];
memset(hex,0,4);
   
for(int i = 0;i<len;i++)
{
   sprintf(hex,&quot;%x&quot;,buffer[i]);
   // hex now contains the string equiv of the hex value
}

//if you just want to output in hex

cout<<hex<<buffer[i]<<endl;
could replace the sprintf

In actuallity, the decimal value is hex which is binary which is octal. You just need to know the conversions for the different representations.
