Answer: A
Explanation:
It clearly shows your out
I can solve it with Java. Here it is:
areaOfSquare = stdin.nextDouble();
double sqrt = Math.sqrt(areaOfSquare);
if(Double.isNaN(sqrt)){
System.out.print("INVALID");
} else {
System.out.print(sqrt);
}
Answer:
Option (B) i.e., Hash is the correct option.

It is also a type of file that is read by the special type algo, it uses the value of the bits in the following computer files which is used to manipulates the single number.

Answer:
Since the question expect us to declare a C-string, the solution code is written in C as follows:
- char ssn[9];
- scanf("%s",ssn);
Explanation:
A C-String is a string written in C language. It is an array of characters. To declare a C-string, we use the keyword, <em>char </em>and then followed with the variable name + brackets and the number of characters in the string. For example, we can create a C-String for the SSN number as in Line 1.
To read standard input into the array, we can use C built-in function, <em>scanf(). </em>Just include a string placeholder, %s, and the variable<em> ssn </em>as arguments to <em>scanf()</em>. This will assign the string input by user to variable <em>ssn</em> as C-String.
