Study Notes
What is a String?
- A string is a group of characters that can be stored in a character array
- Some programming languages treat strings as character arrays internally
- The array of characters are stored in successive memory locations
- A string ends with a null character (\0)
- The null character (\0) is not always required in the declaration of a string.
Example
- The example code demonstrates how to store "Klinsman" as a string in a character array called "name[]"
- The code loops through the string and prints each character until the null terminator ("\0") is reached
- When the "while" loop reaches the null character, it exits the loop
- The code is designed to print each character in the string "Klinsman", demonstrating a basic usage of character arrays to store strings.
What are Strings?
- Strings are a group of characters stored in a character array.
- Many programming languages treat strings as character arrays internally.
- Characters in a string are arranged sequentially in memory.
- A string always ends with a null character ('\0').
Example
- The example code demonstrates how to store a string in a character array and iterate through it using a while loop.
- The program iterates through the string character by character until it reaches the null terminator ('\0').
- The %s format specifier in printf() is used to print a string.
- The program illustrates how to calculate the length of the string.
- The provided example program can be rewritten to achieve the same output without explicitly using the length of the string.
