Question 59

Write in Short Short Answer▾

Can I use “int” data type to store the value 32768? Why?

Edit

Explanation

  • No. “Int” data type is capable of storing values from -32768 to 32767.
  • 32768 can be used as “long int” instead.
  • “unsigned int” can also be used if negative values are not to be used.
  • C compiler will not throw any error when 32768 is assigned to an integer type variable. But the actual value in that integer type variable will be -32768.
  • In C programming language the range or size of integer data type is circular- a value greater than 32767, is automatically converted to next value that՚s, -32768.
  • A value less than -32768 is automatically converted to the next value: 32767.
