  char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive).

  @Mahesh: char type can also be 8-bit character for C/C++
  
  In Java we have it to be 16 -bit I suppose
  
  Although it will have a minimum value of 0 for both the cases as you have told.
  
  Am I correct?

  In C a variable of type char can also hold a -ve value and the range is from -128 to 127. So the min. value taht a char variable can have in C is -128.
  
  If someone want that char variable hold only positive values in C then he/she need to use "unsigned char" instead of "char" while declaring the variable.

  Dear Mahesh,
  You quoted 0 to be the answer.

  Dear Pradeep,
  You are right, Unsigned Char has a min. value of 0.
  While,
  Char has a min value of -128.
  Excellent discussion.
  Thanks to all of you.
