Question

declare the following: a data variable each for a 16-bit signed and an unsigned integer with initial values of 0xa4f1 and 0xc4a7

Answer 1

int16_t signed_integer = 0xa4f1;

uint16_t unsigned_integer = 0xc4a7;

Explanation:

The provided code declares two variables, signed_integer and unsigned_integer, representing a 16-bit signed and unsigned integer, respectively. In hexadecimal notation, the initial value of signed_integer is 0xa4f1, and for unsigned_integer, it is 0xc4a7.

A 16-bit signed integer can represent values in the range of -32768 to 32767. The hexadecimal value 0xa4f1, when converted to decimal, is 42257. This value falls within the valid range for a 16-bit signed integer.

On the other hand, a 16-bit unsigned integer can represent values from 0 to 65535. The hexadecimal value 0xc4a7, when converted to decimal, is 50343. This also falls within the valid range for a 16-bit unsigned integer.

In summary, the declared variables are appropriately initialized with values that are within the valid range for both 16-bit signed and unsigned integers. The hexadecimal values provided ensure that the variables hold meaningful data and won't cause overflow or underflow issues within the specified data types.

Answer 2

To declare a 16-bit signed integer with an initial value of 0xa4f1 and an unsigned integer with an initial value of 0xc4a7 in a programming language like C or C++, you would write:

int16_t signedInteger = 0xa4f1;

uint16_t unsignedInteger = 0xc4a7;

Step-by-step explanation:

In C and C++, the int16_t and uint16_t types are used for 16-bit signed and unsigned integers, respectively. The int16_t type can hold signed integer values, while uint16_t is used for unsigned integers. The given code snippet declares two variables, signedInteger and unsignedInteger, of these respective types and initializes them with the specified values.

It's important to use the correct data types to ensure proper memory allocation and interpretation of the values. The 0xa4f1 and 0xc4a7 values are hexadecimal representations of the initial values for the signed and unsigned integers.
