Which of the following defines the C-string containing “Hello”?

Question

a. char stringVar[10] = “Hello”;
b. char stringVar[10] = {‘H’, ‘e’, ‘l’, ‘l’, ‘o’};
c. char stringVar[10] = {‘H’, ‘e’, ‘l’, ‘l’, ‘o’, ‘\0’};
d. char stringVar[6] = “Hello”;
e. char stringVar[] = “Hello”;

Answer 1

a) c) d) e)
Explanation: Note that a) and c) have the same size C-string variable and have the same size C-string. d) and e) have the same size C-string variable and have the same size C-string, but the size of the C-string variable is different from a) and c). The character array in b) is not terminated, so the array does not contain a C-string at all.
