problem in HExadecimal to decimal conversion

[Rupali12345]

Hi all,

 
      int main() 
       { 
           FILE *fp1;
        char *c, *d;
        c  = new char[54];
        d = c;
                      fp1=fopen("C:\\xyz.dcm","r");
           for(int i=128;i<=163;i++)
        {
            fseek(fp1,i,SEEK_SET);
          *d =(char )fgetc(fp1);
          d++;
          cout<<*c++;
        }
        for(int j=164;j<=166;j++)
        {
 
          fseek(fp1,j,SEEK_SET);
           cout <<dec <<  fgetc(fp1) <<endl;
         }
 
         return 0;        
 
      } 
 

in this code, 164th byte from file is 1a. it is displaying as -1 instead of 26 ie decimal value.
what should i have to do to get 26 as a decimal value of 1a????

How are you getting 1a in a byte? 1a is two bytes. If have 26 in byte 164 then is should display 26. fgetc() returns an int so << fgetc() should show 26. A char with 26 is not displayable.

BTW, you should be using ifstream instead of the C file functions.
