Other Features of Strings

• In C, strings are represented as arrays of characters, and there are several features and functions associated with working with strings.
• Here are some key aspects:
• Null-terminated:
  C strings are null-terminated, meaning they end with a null character ('\0'). This character is used to indicate the end of the string.
• String functions:
  C provides standard library functions for string manipulation, such as strlen (to find the length), strcpy (to copy strings), strcat (to concatenate strings), and many more.
• Array of characters:
  Strings are essentially arrays of characters, and individual characters in a string can be accessed using array notation.
• String input/output:
  You can use printf and scanf functions to input and output strings. The %s format specifier is commonly used for strings.
• String literals:
  Strings can be represented as string literals, enclosed in double quotes. For example: "Hello, World!".
• Here's a simple example demonstrating some of these features:
Program.c
#include <stdio.h> #include <string.h> int main() { // String literal char greeting[] = "Hello, World!"; // Output the string printf("String: %s\n", greeting); // Find the length of the string int length = strlen(greeting); printf("Length: %d\n", length); // Accessing individual characters for (int i = 0; i < length; ++i) { printf("Character at index %d: %c\n", i, greeting[i]); } return 0; }

Output:
String: Hello, World!
Length: 13
Character at index 0: H
Character at index 1: e
Character at index 2: l
Character at index 3: l
Character at index 4: o
Character at index 5: ,
Character at index 6:
Character at index 7: W
Character at index 8: o
Character at index 9: r
Character at index 10: l
Character at index 11: d
Character at index 12: !
