Chapter 7: Problem 12

Look at the following array definition. char day[ ] = "Tuesday" How many elements are in the day array? Is the string stored in the day array terminated by a null character?

Short Answer

Expert verified

Answer: The "day" array has a total of 8 elements, and the string stored in it is indeed terminated by a null character (\0).

Step by step solution

Count the characters in the string

The string "Tuesday" has 7 characters: T, u, e, s, d, a, and y.

Find the size of the array

In C, a string is stored as an array of characters, with each character storing one element in the array. Additionally, the string is terminated with a null character (\0). Therefore, the "day" array will have one extra element in it to store the null character. The day array will have a total of 7 characters (from the string "Tuesday") + 1 null character, which equals 8 elements.

Check for null character

A C string is always terminated with a null character (\0), which marks the end of the string. The day array has that extra element for the null character. So, the string in the day array is indeed terminated by a null character.

Conclusion

The day array has a total of 8 elements, and the string stored in it is terminated by a null character (\0).
