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.

The answer to this question is given below in the explanation section.
Explanation:
First, we need to convert these hexadecimal numbers into decimal numbers, then we can easily identify which one is the lowest hexadecimal.
The hexadecimal numbers are F2, 81, 3C, and 39.
F2 = (F2)₁₆ = (15 × 16¹) + (2 × 16⁰) = (242)₁₀
81 = (81)₁₆ = (8 × 16¹) + (1 × 16⁰) = (129)₁₀
3C = (3C)₁₆ = (3 × 16¹) + (12 × 16⁰) = (60)₁₀
39 = (39)₁₆ = (3 × 16¹) + (9 × 16⁰) = (57)₁₀
The 39 is the lowest hexadecimal number among the given numbers.
Because 39 hex is equal to 57 decimal.
39 = (39)₁₆ = (3 × 16¹) + (9 × 16⁰) = (57)₁₀
Answer:
The answer is "True".
