  • By default, integers are signed . Hence instead of signed int , we can directly use int .
  • signed and unsigned can only be used with int and char types.
    so its correct…
#7

but in line 4, it is written “signed CodingBlocks = 9” and int or char is not mentioned in this line then how will the compiler know it is int?

#8

basically if we assign any character value to signed and the print the same the we get ascii value of that character as the output…
