Length of the String without using strlen()

Without using the strlen():-

 #include<stdio.h>
  void  main() 
   { 
   char a[20],i;
   printf("enter the string:-");
   scanf("%s",a); 
   for(i=0; a[i]!='\0'; ++i);
   printf("length of the string: %d",i); 
   }

enter the string:-abc
length of the string:3

Using the strlen():-

#include<stdio.h>
#include<string.h>
void main()
 {
   int len;
   char a[20];
   printf("enter the string:-");
   gets(a);
   len=strlen(a);
   printf("%d",len);
 }
