Question

float num1;
short num2;
22
Long num3;

What is the data type of num1 - num3/num2?
1​

Answer 1

Float

Explanation:

• num1 is a variable of float.
• num2 is a variable of short int.
• num3 is a variable of long int.
• The size of float is 4 bytes, size of short int is 2 bytes and the size of long int is 4 or 8 bytes.
• In (num1 - num3)/num2, before solving it, the data types are type casted.
• In given variables, highest data type is float. So, all variables are converted into float datatype.
• So, num1, num2 and num3 will become the float data type.
• If we subtract float from float (num1 - num3), we get float datatype.
• Also, if we divide float with float ((num1 - num3)/num2), we get float datatype.

Therefore, the data type of (num1 - num3)/num2 is float.
