C Program to Find the Length of the String


This C Program uses recursive function & counts the number of nodes in a linked list. A linked list is an ordered set of data elements, each containing a link to its successor.

Here is the source code of the C program to count the number of nodes in a linked list. The C Program is successfully compiled and run on a Linux system. The program output is also shown below.

  4. #include <stdio.h>
  6. int find_len (char [], int);
  8. int main ()
  9. {
  10. 	char str[100];
  11. 	int len = 0;
  13. 	printf ("Enter the string: \n");
  14. 	scanf ("%[^\n]s", str);
  16. 	len = find_len (str, 0);
  18. 	printf ("The length of the given string is: %d\n", len);
  19. 	return 0;
  20. }
  22. int find_len (char str[], int index)
  23. {
  24. 	static int l = 0;
  26. 	if (str[index] == '\0')
  27. 		return l;
  28. 	else
  29. 		l ++;
  31. 	find_len (str, index + 1);
  32. }
