Answer:
cout << setprecision(2)<< fixed << number;
Explanation:
The above statement returns 12.35 as output
Though, the statement can be split to multiple statements; but the question requires the use of a cout statement.
The statement starts by setting precision to 2 using setprecision(2)
This is immediately followed by the fixed manipulator;
The essence of the fixed manipulator is to ensure that the number returns 2 digits after the decimal point;
Using only setprecision(2) in the cout statement will on return the 2 digits (12) before the decimal point.
The fixed manipulator is then followed by the variable to be printed.
See code snippet below
<em>#include <iostream> </em>
<em>#include <iomanip>
</em>
<em>using namespace std; </em>
<em>int main() </em>
<em>{ </em>
<em> // Initializing the double value</em>
<em> double number = 12.3456; </em>
<em> //Print result</em>
<em> cout << setprecision(2)<< fixed << number; </em>
<em> return 0; </em>
<em>} </em>

Answer:
FFF4
Explanation:
Binary representation of 12 = 00001100
Expressing it in hexadecimal format : 0C
Binary representation of -12:
Step 1 : Computing 1's complement for 12 =11110011
Step 2 : Adding 1 to 1's complement to get the 2's complement =>
11110011+1 = 11110100
Converting the 2's complement representation to hexadecimal format:
F4 ( 8 bit representation) or FFF4 ( 16 bit representation)
