Malware can be hugely damaging to businesses as well as individuals. Hackers often use malware to try and gain entry into an organisation's systems or networks, from where they can access valuable data to steal and sell on.
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>
<em />
Answer:
Code works perfectly
Explanation:
There is nothing wrong with your program as it runs perfectly and displays the expected results.
You may need to compile with another compiler if you're not getting the required results.

Answer:
The above query gives an error.
Explanation:
- The query gives an error because is not the correct syntax of the select or inserts query.
- The syntax of the select query is as follows: "select Attributes_1_name, Attributes_2_name,...., Attributes_n_name from table_name;".
- The syntax of the insert query is : "insert into table_name (column_1_name, column_2_name,...,column_n_name) values (column_1_value, column_2_value,...,column_n_value);".
- The syntax of the insert and select query is : "insert into table_name (select Attributes_1_name, Attributes_2_name,...., Attributes_n_name from table_name);".
- But the above query does not satisfy any property which is defined above. Hence it gives a compile-time error.
