Answer:
c. double triple(float n) { return (3 * n); }
Explanation:
In option a print is used to print integer.While printf is used in C to print something.
In option b there is no * operator between s s s it should be s*s*s.So it will give error.
In option d there is also no multiply operator * in between 3.14 2 r it should be 3.14*2*r.
So we can say that option c is error free.
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.
