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).

sarveshgupta@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? -
rengarajSir,

pradeep_agrawalIn 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.

rengarajDear Mahesh,
You quoted 0 to be the answer.
But it is for unsigned char . not for char.
