Chapter 10: Problem 4

Look at the following code. What value will be stored in s after the code executes? char name [10] int \(s\) strcpy (name, "Jimmy") \(s=\) strlen (name)

Short Answer

Expert verified
Answer: The value of the variable "s" will be 5.

Step by step solution

01

Understanding the strcpy() function

The strcpy() function is a string function in C programming language that is used to copy a string from one memory location (source) to another memory location (destination). In this case, it copies the string "Jimmy" into the character array "name".
02

Understanding the strlen() function

The strlen() function is another string function in the C language that calculates the length of a string. It takes a string as an input and returns the number of characters in the string, excluding the null character ('\0') at the end.
03

Apply functions to the code and find the value of "s"

We are given the code: ``` char name[10]; int s; strcpy(name, "Jimmy"); s = strlen(name); ``` After executing strcpy(name, "Jimmy"), the character array "name" will store the string "Jimmy". Now, we need to find the length of this string using strlen() function. The string "Jimmy" has 5 characters. Therefore, when we execute s = strlen(name), the length of "name" will be 5. So, the value of "s" will be 5.
