# include <iostream>

using namespace std;

int main(){

cout << "Please enter four ASCII characters: ";
char Num[500];  //<--- You must dimension proper size
gets(Num);


int len = strlen(Num);
std::hex;
Num[len+1] = Num[len+2] = Num[len+3] = 0;

To display an hex number just do this

cout << hex << aNumber;

tedschnieders,

two ways of doing this easy:

#include <iostream>

using namespace std;

int main()
{

      cout << "Please enter four ASCII characters: ";
      char Num[500];  //<--- You must dimension proper size
      gets(Num);

      // do something ...


      // integer array
      int iNum[500];
      for ( int i = 0; i < strlen ( Num ); i++ )
      {
            iNum[i] = Num[i];
      }

      for ( i = 0; i < strlen ( Num ); i++ )
      {
            cout << "0x" << hex << iNum[i] << endl;
      }

      return 0;

}

OR

#include <iostream>
#include <stdio.h>

using namespace std;

int main()
{

      cout << "Please enter four ASCII characters: ";
      char Num[500];  //<--- You must dimension proper size
      gets(Num);

      // do something ...

      for ( int i = 0; i < strlen ( Num ); i++ )
      {
            printf ( "0x%x\n", Num[i] );
      }
      return 0;

}
