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.
