Thread: converting chars to ascii equivilant

How do I convert characters (in arrays and strings) to its respective ascii value. I want to do that so I can encrypt some variables for a save file, to prevent tampering(or at least not useful tampering). Thanks.

Stoned_Coder is right.

But for knowledge sake, use the stty raw echo command. Get the input and the raw echo will convert it to hex.

Code:

#include <stdio.h>
#include <stdlib.h>

void main(){

   
   char input;
   system("stty raw -echo");

   printf("This program is designed to convert characters into hex"
      " value\n\r");
   printf("Press q at any time to quit this program");
   while(input != 'q'){
      fflush(stdin);
      printf("\n\rPlease enter a character:");
      scanf("%c", &input);
      printf("\n\rChahrater entered:	%c", input);
      printf("\n\rHexidecimal value:	%x", input);
      printf("\n\n\rPress q at any time to quit this program");

   }
   printf("\n\r\n\rThank you\n\r");
      system("stty -raw echo");
}

This is just a little C that I put together for you...lol Just to test that conversion works......printf. Object oriented is pretty much the same way.


But this will not make anything secure!!!
