  • Signed and unsigned char both are used to store a single character. The characters are stored as per their ASCII values. For example, ‘A’ will be stored as 65 as it has value ‘65’ in the ASCII table.
  • You don’t need to specify keyword ‘signed’ for using signed char but you need to mention keyword ‘unsigned’ for using unsigned char. i.e.
  • Instead of writing

signed char name = ‘a’;

  • you can simply write it as :

char name = ‘a’;

  • but in the case of unsigned char, you need to use ‘unsigned’ keyword.

unsigned char name = ‘a’;

  • The size of both is same i.e. 1 byte or 8 bits.

  • ASCII table has 128 characters ranging with values from 0 to 127. The remaining 127 characters is known as extended ASCII character set.

  • In signed char, the extended set takes value from -128 to -1 whereas in unsigned char it takes value from 128 to 255.

  • Thus the range of signed char is -128 to 127 whereas that of unsigned char is 0 to 255.

  • If you try to give value 128 to signed char, it will take value corresponding to the other side of the range i.e. -128. For signed char, the value next to 127 is -128 like in clock after 12 comes 1 and so on. :smiley:

  • Similar if you try to give value 256 to unsigned char, it will take value 0.

  • Just use them according to your requirement.
